Mariano Avila was born in México City, where he served as pastor of six Presbyterian churches. He has also served in the Seminary of the National Presbyterian Church as professor, academic dean, and president, and was professor of Biblical Studies at the Comunidad Teológica de México. He was Academic Dean of the Facultad Latinoamericana de Estudios Teológicos (Miami, Florida), and is a member of the Academic Council of PRODOLA, the doctoral program (Ph.D.) for professors, leaders, and pastors in Latin America. For several years he was coordinator of urban ministries for community transformation and theological adviser for World Vision México, and was also advisor for the Spanish ministry of CRC Publications.

Mariano was a member of the Biblical Translation Committee (International Bible Society) that produced the Nueva Versión Internacional and also he is one of the translators of the Traducción en Lenguaje Actual (United Bible Societies), a translation in contemporary Spanish from the original languages. He has translated books from English and Portuguese into Spanish, and has published a good number of articles and books. His most recent publications in Spanish are Entre Dios y el Cesar: Líderes evangélicos y política en México (Between God and Cesar: Evangelical leaders and politics in Mexico), and Carta a los Efesios. Comentario para exégesis y traducción(Letter to the Ephesians. A Commentary for exegesis and translation). Prof. Avila teaches, lectures and preaches in different seminaries and churches in the Americas and other parts of the world. Mariano’s rich experience in pastoral and teaching ministries, Bible translation, community transformation, and the academic world has equipped him to effectively train students for ministry:

“In my own experience as a pastor, educator and also in training others for diverse ministries, I found that there are three sine qua non tools for a significant ministry in our complex world: a solid knowledge and love for Scriptures, a well articulated Reformed world and life view, and a good understanding of the cultural, social, and political realities we want to transform so that they may express Jesus’ Lordship over all of creation. I am convinced that God’s gifts to his Church are well equipped servant leaders who will lead and train God’s people for service in a world that urgently needs salvation, justice, reconciliation, and shalom.”

Mariano Avila is married to Rosa María and has two married adult sons, Mariano III to Kate and Luis to Amanda, and one grandson, Luis Jr.

Professor of Systematic Theology B.S. (Calvin College, 1970) B.D. Th.M. (Calvin Theological Seminary, 1973, 1977) Ph.D. (University of St. Michael’s College, 1982)

John Bolt has served as pastor of Christian Reformed churches in Pencticton and Kelowna, B.C. He began his teaching career at Calvin College in the Department of Religion and Theology. John moved from there to teach at Redeemer College, Ancaster, Ontario. After seven years in Ontario, John came to Calvin Theological Seminary where he now teaches systematic theology. For John, the task of the systematic theologian is to pay attention to the big picture of the Christian faith, to summarize the grand truths of scripture in a coherent way, and listen closely to the voices of important theologians throughout church history. John’s goal is to communicate to students the vision of the Christian faith from a Reformed perspective.

“By background, training, and conviction I am a Reformed theologian. What especially excites me about the Reformed tradition is its bigness, its grand kingdom vision of Christ’s universal lordship. This vision, which gives dignity and worth to human vocation and hope in the midst of an uncertain age, is what I want above all to communicate to my students. My vision for Calvin Theological Seminary is that it will increasingly become a center for training students from all over the world in the Reformed Christian faith. I believe this faith is the hope of the world.”

John is married to Ruth, and has three children and nine grandchildren.

John Bolt is author of The Christian Story and the Christian SchoolStewards of the Word, and A Free Church, A Holy Nation: Abraham Kuyper’s American Public Theology. He is also the editor of the four volume English edition of Herman Bavinck’s Reformed Dogmatics.

Not only that, but Dean has taught in a variety of settings, including Asian Theological Seminary in the Philippines, Classis Red Mesa, in New Mexico, and now Calvin Theological Seminary. His aim in the classroom is to equip students for a full life of teaching and preaching through his classes on the New Testament. He values conversations with students about goals in ministry and detailed discussions about Jesus’ sayings and teachings.

“In the increasing search for meaning in the twenty-first century, we have to open anew a window to the life, ministry, and death of Jesus. This captivating person of the first century who now rules over every inch of his creation is both the target of our study and the Lord who by his Spirit enables us to understand His life and work. I rise up every morning with the excitement of discovering more of the significance of this pivotal figure in earth’s history. I hope that my students will be stimulated to deepen their understanding of this person about whom ‘even the whole world would not have room for the books that could be written’ (John 21:25).”

Dean wrote his master’s thesis on ”The Salt Sayings of Jesus” and his doctoral dissertation on “The Sayings of Jesus in the Epistle of James.”

Ronald Feenstra’s area of professional training and teaching is systematic and philosophical theology. He earned his Ph.D. at Yale; his dissertation topic was Pre-existence, Kenosis, and the Incarnation of Jesus Christ. He taught theology at Marquette University for eight years before coming to Calvin Theological Seminary. In addition to teaching, he oversees the Ph.D. program, which is designed to attract students from diverse backgrounds and to encourage students to pursue a scholarship that wrestles with the theological issues of the day.

“Theological education in the Reformed tradition draws upon a rich biblical, confessional, and theological heritage. My goal in teaching is to illuminate that heritage in such a way that people will be drawn into it and understand it more fully, thereby coming to a renewed sense of the mystery and power of the gospel. I also try to set Reformed theology in the context of the broader Christian tradition. I thoroughly enjoy studying and learning theology alongside my students and I hope that their study at Calvin Theological Seminary both equips and encourages them to engage in vigorous, faithful Christian ministry.”

Ronald is married to Barbara and they have three daughters. His interests include child rearing, current events, reading, jogging, and bicycling.

Theological Librarian

Paul Fields is a theologian with an emphasis on service. Paul has degrees in history, systematic theology and library science. His responsibility as a theological librarian at Calvin Theological Seminary is to provide access to theological materials in a timely, efficient and up to date way. Paul is also the curator of the H. Henry Meeter Center for Calvin Studies and specializes in the collecting, care, and preservation of rare collections from the sixteenth century.

“Reformed education recognizes that work done in the study is a matter of thinking God’s thoughts after him as his revelation in Scripture and nature is studied. Such ongoing education can only call for humble, worshipful scholarship. When students work and live in the context of such scholarly service to God, they minister with integrity and speak the truth with conviction -truth based upon God’s revelation in Scripture. My hope is that both students and faculty will also live in such a way that appreciation for God’s grace and his primacy in all things is evident.”

Professor Leder’s career began with a position as a pastor in Ontario, Canada. From there he spent eight years as a missionary with Christian Reformed World Missions.

His goal is to take the teachings of the Old Testament and help students to see how these teachings inform Reformed theology. Professor Leder’s areas of special interest are the Pentateuch and church architecture.

“My research interests focus on the Pentateuch, specifically Exodus and Leviticus, and church architecture as it relates to the function of the space dedicated to worship. My interests also extend to an examination of the Bible-and specifically the Old Testament-in a variety of mission contexts. These converge with the pedagogical goal of emphasizing the crucial role of the Bible in the ministry of the church and its critical function in the church’s missionary struggle with its detractors and opponents at home and abroad.”

While I was still in high school, I received a very direct call from God to spend my life in ministry. That call has always been first and foremost a call to preach the Gospel, because, as Paul says in Romans 8, "faith comes from what is heard, and what is heard comes by the preaching of Christ." It has been my joy to preach Christ for 45 years now and my privilege to see faith take root and flourish in response to that preaching. Stan is approaching 50 years of marriage.

President B.A. (Trinity Christian College, 1982) J.D. (University of Florida, 1984) M.Div. (Calvin Theological Seminary, 1995)

Julius Ted Medenblik, the eldest son of Lambert and Martha Medenblik (nee Vander Ploeg) was born in Kalamazoo, Michigan, in 1960. His family became charter members of Faith Christian Reformed Church and for a short time he attended Kalamazoo North Christian School. In 1966 the family returned to the Fulton, Illinois, area when his father purchased the family farm that had been previously rented by Jul’s grandfather. There Jul attended Fulton Christian Grade School and Fulton Community High School, and the family joined Bethel Christian Reformed Church, also in Fulton.

After high school, Jul attended Trinity Christian College in Palos Heights, Illinois. He graduated with a major in Philosophy and double minors in English and History while on a pre-law track that included a semester internship at a legal aid clinic in Harvey, Illinois. While at Trinity, he met Jackie Klain from Lansing, Illinois. Three weeks after graduation, Jul and Jackie were married, and three days after that they moved to Gainesville, Florida, where Jul entered the University of Florida Law School. During his law school days, Jul served as research assistant for Professor Joseph W. Little.

After graduating with a Juris Doctor degree cum laude, Jul obtained a position as an associate in the law firm of Stewart, Call, Byrd & Rozelle in Palm Beach, Florida. The Medenbliks joined Lake Worth Christian Reformed Church in Lake Worth, Florida, where Jul served as a Sunday School teacher and superintendent, catechism teacher, elder, and eventually chair of a Pastoral Search Committee. It is during those years that he felt called by God to ordained ministry, and in 1991 Jul, Jackie, and their four-year-old son, Joshua, left Florida and entered a Master of Divinity program at Calvin Theological Seminary. While at CTS, Jul did a summer assignment at Providence Christian Reformed Church in Holland, Michigan, and a full-year internship at First Calgary Christian Reformed Church in Calgary, Alberta, Canada. It was during the internship year that their daughter Julianne was born.

Following graduation in 1995, Jul accepted a call to Orland Park CRC in Orland Park, Illinois, to be the founding pastor of a church plant in New Lenox, Illinois. New Life Christian Reformed Church began worship services in a public high school auditorium in 1996, was organized as a congregation in 2002, and moved into its own building in 2003. During this time the church expanded from one to three worship services with over 700 people in total attendance.

Jul has served as a former board member and president of the CRC Loan Fund; former board member and president of the Chicago Christian Counseling Center; former board member and chair of the Classis Chicago South Home Missions Committee; Synodical Deputy from Classis Chicago South; board member and president of the Calvin Seminary Board of Trustees; synodical delegate to the synods of 1990, 2002, and 2006; and Church Planting and Development Point Team Leader for Christian Reformed Home Missions.

Upon receiving this latest appointment, Rev. Medenblik stated, “I am humbled by the opportunity to move from serving the church as a local pastor and in various denominational settings to the presidency of Calvin Theological Seminary. One picture that we have in church planting in the Christian Reformed Church is embodied in the phrase, ‘Deep Roots, New Branches.’ Calvin Theological Seminary is deeply rooted in and nurtured by the church. We have a great opportunity to use those roots to nourish preachers and church leaders for the ministries and new opportunities that await us in the mission field around each and every one of us.”

“My excitement for preaching has everything to do with Jesus.” John Rottman’s love for Jesus has been there as long as he can remember, and his love for theology, at least as far back as grade 3! John pursued this passion with an undergraduate degree in philosophy and Greek, and continued in Toronto with graduate studies in theology. John spent five years working in a psychiatric hospital and it was during that time that John felt a call to the pastorate – but wasn’t so sure about preaching. This changed during his time in seminary. While writing his first sermon at Calvin Theological Seminary, he felt strongly that this was another piece of his calling. It is with a strong theological training, and understanding of the role of the Holy Spirit in preaching, that John now equips students to bring proclaim the gospel through the medium of preaching.  Recently, John has become involved with seminary education in prisons.

“Now after preaching for nearly twenty years and teaching it now for twenty, I have learned some things about preaching, even as I continue to struggle. As preachers we are vulnerable in the pulpit and perhaps never more so than as students. I am reminded of this every time I preach and especially when I preach one of my own sermons to a preaching class.As a teacher of preaching I welcome the challenge of learning with my students as we together invite God to shape us as preachers and disciples of Jesus.”

John is married to Marilyn and they have three adult children.

Professor of Historical Theology A.B. (Dordt College, 1989) M.Div. (Calvin Theological Seminary, 1993) M.A., Ph.D. (University of Notre Dame, 1997, 2000)

David Rylaarsdam began his teaching career at Smith Memorial Bible College in Nigeria, and since has taught at the University of Notre Dame, Dordt College in Sioux Center, Iowa, and now, Calvin Theological Seminary. He has also served a variety of churches as interim pastor and received missionary training in Mexico City. David sees church history as an opportunity to listen to testimonies of older brothers and sisters in the faith.

“As my students and I listen, we respond to these testimonies in our writing and reflection, in our discussions, in what we believe and in how we live. In other words, we are drawn into conversation with these believers spread through all time. We become part of their community. I relish being a leader and participant in this community discussion, a guide and fellow inquirer with my students as our faith seeks understanding, as we seek guidance from our sisters and brothers of all ages in how to read Scripture, how to make disciples, how to discern wisely the spirits of our age, how to avoid the mistakes of the past. I pray that my students will be persuaded to perceive the story of God’s people as their story so that they may grow wiser and be drawn into a richer, more intimate union with God, the main actor in their stories.”

David is married with three children.

David has contributed to numerous publications and presentations. His dissertation topic was “The Adaptability of Divine Pedagogy: Sugkatabasis in the Theology and Rhetoric of John Chrysostom.”

Calvin Van Reken is an ordained minister in the Christian Reformed Church. He has served as pastor at two churches, Momence Christian Reformed Church, Momence IL (1982 – 1986) and Peace Christian Reformed Church, South Holland IL (1986 – 1991). Calvin has taught various philosophy and theology courses at Harper College, Calvin College, Trinity Christian College, Calvin Theological Seminary, Western Theological Seminary, and in Limuru, Kenya. He served as member and president of the board of the Back to God Hour and has published articles and devotional materials dealing with moral issues, worship, and the church.

“My own area of special interest is ethics-the study of morality. In teaching about moral matters, I stress that our salvation does not rest on our obedience to moral rules. Rather, our desire to know God’s will and obey it arises as a result of the saving grace that is ours through faith in Jesus Christ. I continually try to understand more completely how we can best live in response to all we are and have in Jesus Christ. God’s people are confronted with many difficult choices and they need guidance in making them. For examples: is in vitro fertilization a morally permitted way to conceive a child? Or, may I work for a corporation when its policies are harming the environment? My prayer is that I will be effectively used by the Lord to equip students in understanding more fully how God wants us to live.”

Calvin is married to Rosella and they have three daughters – Rebecca Rose, Erica Ruth and Marissa Joy.

Mary’s goal as a professor is to not only help her students understand the truths of theology, which can often seem abstract and difficult, but also to help them understand that theological understanding and piety are intimately intertwined.

“My students will tell you that I always ask the ‘So what?’ question. When I teach a concept, no matter how abstract it might seem, I try to give my students an idea of why it’s helpful for ministry, for understanding God, and for moving through life…My kids have taught me that if it doesn’t touch them in some way, what good is it?”

Howard D. Vanderwell is a recently retired Christian Reformed Church pastor after serving congregations for 40 years in Iowa, Illinois and Michigan. At Calvin Theological Seminary, his responsibilities include teaching courses in the Introduction to Christian Worship, The Doctrine of Christ and Services of the Christian Year, and Planning and Leading Congregational Worship. Howard is able to speak on numerous issues related to worship, and has done so at various retreats and churches. Howard’s interests include planning, leading and evaluating worship, series preaching, and worship renewal throughout the evangelical church.

“My life-long prayer, from my days as a child, was that I might be honored to serve as a Christian Reformed pastor preaching the Word of God to encourage and challenge his people. I consider the forty years of my pastoral ministry to have been the most valuable way in which I could have invested those years! When I consult with pastors, teach and mentor students, hold conferences for worship leaders, or write worship planning materials, my aim is to equip and inspire others to serve their Lord and Savior by making a whole-hearted investment in his church and his people. Such ministry is certainly not without its stresses and discouragements, and those of us who have found such joy in a life-time of ministry are uniquely fitted to encourage them.”

Howard is married to Eleanor, and they have three married sons, and ten grandchildren from ages 5 through 19. His hobbies are yard-gardening, walking, photography and model railroading.

John D. Witvliet is director of the Calvin Institute of Christian Worship and professor of music and worship at Calvin College and Calvin Theological Seminary, respectively. He also teaches in the religion department at Calvin College. His areas of interest include the history of Christian worship, worship practices in various denominations, biblical and systematic theology of worship, the role of music and the arts in worship, and consulting with churches on worship renewal.

“At its best, Christian worship reflects and conveys the beauty of God, profound gratitude for the gospel of Christ, and eagerness to deepen self-giving service in God’s world. In my teaching, I hope to invite pastors and worship leaders to plan and lead services that reflect this vision, to offer worship that is both profoundly biblical and culturally relevant. An important part of this learning process is encountering the wisdom of Christian communities in cultures and historical periods very different from our own. Such encounters deepen our sense of solidarity with the whole body of Christ, and also sharpen, humble, and enrich our ministry.”
