Garrett’s professor of evangelism reflects on a faith-filled legacy

Garrett Seminary joins United Theological Seminary in celebrating the Reverend Dr. Mark R. Teasdale, Garrett’s E. Stanley Jones Professor of Evangelism, who has accepted the call to serve as United’s next President. “Mark has been a trusted and vital member of our faculty and a beloved teacher and advisor to our students. After 18 years of faithful teaching and serving in multiple administrative and leadership roles, we wish Mark all success in this new endeavor, and thank him for all he has given to Garrett,” says President Javier A. Viera. “United Theological Seminary will be well-served by the care and intention he brings to his work, by his scholarly and leadership prowess, and by his passion for growing Christian communities.”
For his part, Dr. Teasdale shares that he feels his time at Garrett has been the best possible training ground for learning how to shepherd United through its next chapter. “Garrett has taught me how to appreciate, understand, and engage across such a phenomenally broad spectrum of theological, cultural, and ethnic difference,” Dr. Teasdale says. “That’s a big part of what I’m bringing to my new role: United is home to students from 55 denominations, more than half of whom are African-American. I want to be the kind of leader who empowers the unique gifts everyone brings, not someone who layers over them with my vision for how we do things.”
Indeed, reflecting on nearly two decades serving Garrett, Dr. Teasdale expresses admiration for how the seminary uses shared Christian values to cultivate community without suppressing particularity. “There’s clarity about Jesus being at the center of our shared life. Who we see Jesus to be may be very different—we don’t have to agree even on all big-ticket issues in the social or political arena—but we can all agree that Jesus is good, that we all have value,” he explains. “That’s really important, because one of the things that happens in a polarized world is that it becomes easy to diminish or even disregard the value of another human being, just because we disagree with them. But the Garrett seminary classroom has always been a place to bring people together.”
Dr. Teasdale’s commitment to building connection, even across significant difference, is manifest in his relationships among Garrett’s faculty, as well. “Mark is deeply collegial in his work. He is deeply committed to building a culture of collaboration where diverse voices are reflected in the decisions we make together as faculty and administrators.” says Dr. Jennifer Harvey, Garrett’s Vice President for Academic Affairs. “At the same time, he brings this same intention and integrity to Garrett’s academic culture supporting students in their projects and in achieving the high expectations he sets. So many students share with me that he is huge reason they’ve felt at home in our midst.”
That collegiality doesn’t stop simply because Dr. Teasdale is no longer on the faculty. “I look forward to relating to President Viera as a colleague in the broader work of fostering and sustaining theological education,” he says. “I’m hoping Garrett is not somewhere I’m leaving behind but is instead a place that I now get to relate to in a new way.”
In reciprocating that collegiality, President Viera emphasizes their shared commitment to strengthening the church and academy. “Mark is wondrously thoughtful about how Christian communities can spiritually and ethically engage the world around them, inviting people into our spiritual life while also collaborating to mend a fractured culture,” he says. “We need more seminarians who are trained in that spirit. I look forward to continuing to have Mark as a strategic partner and collaborator in that work.”
Ultimately, as he prepares to move into a new seminary home, Dr. Teasdale is filled with gratitude. “I’ve had the opportunity to work for multiple presidents, multiple deans. They put trust in me, not just to teach but to also serve administratively—even the opportunity in last couple years to be part of the real estate task force and negotiate with Northwestern University as we prepare to move into new buildings,” he notes. “It’s been an honor to serve this community.” Ever the evangelist, he’s keen to offer reflection on the gospel values that guide faithful institutional stewardship. “As leaders, we’re not here to serve ourselves,” he concludes with a smile. “We bear fruit and the fruit is for the world to eat, not for us. It’s how the seeds go out and get planted elsewhere. Trees don’t bear fruit for themselves—they do it for the next generation and for others.”
