As part of Mosaic’s ordination process, pastors and ministry leaders must take four courses through the Mosaic Institute. My first course, titled “Introduction to Mosaic Conference,” was taught by Executive Minister Stephen Kriss and Leadership Minister for Formation Rose Bender Cook. This class focused on the origins of Anabaptism, the evolution of the Mosaic Conference, and what it looks like today.
The course included several assignments and experiences, ranging from Zoom lectures and readings to field trips and projects. One of the main elements was hearing each other’s “path towards Anabaptism,” encapsulated in our life stories. Many of these stories were heartbreaking, some even funny, but all unique. Even with just eight people in our group, we represented many different cultures and ethnicities. There is one thing that brought us all together: the way that Jesus has moved in each of our lives.
Most of these stories were told throughout the intensive portion of our class, in which we spent four days together in the Souderton and Philadelphia area for hands-on learning and relationship building. We began by meeting at Zion Mennonite (Souderton, PA), for dinner. Here we began learning about Anabaptism through Zion’s history in that community.

Our first full day began at the Conference-Related Ministry Mennonite Heritage Center (Harleysville, PA), led by Joel Alderfer and Regina Wenger. This is a phenomenal museum that outlines the complicated history of the Anabaptist movement and Mennonite people with preserved artifacts, alongside a glimpse of where Mennonites are today.
After a quick lunch at a Vietnamese restaurant, we went to the Conference-Related Ministry Penn Foundation (Sellersville, PA) and met with Chaplain Sue Howes. There, we learned about how this institution was founded: many drafted Mennonites worked in sanitariums, the mental hospitals of that time, in lieu of active military duty. When they saw the deplorable conditions of these “hospitals,” they bravely exposed the truth. The outcry in response allowed the establishment of the Penn Foundation, which was one of the first institutions to treat mentally ill people with dignity. The following day began at the Conference-Related Ministry Germantown Mennonite Historic Trust in Philadelphia where we stood at the site of the first permanent Mennonite meetinghouse in America. This community fought for justice and loving its neighbor, even as people seeking refuge in a foreign land. They created the first formal written petition against slavery, and though the petition never gained enough traction to have any effect, I was encouraged to learn that Mennonites have been standing up for justice since the beginning.

We then journeyed to Rittenhouse Town, a small Mennonite village created around one of the first independent paper mills in the area. This paper mill allowed them to print their own Bibles without being taxed by Britain for the paper. The paper mill, and the community that formed around it, helped that area prosper and slowly become what the Philadelphia area is today, all owed to the Rittenhouse Mennonites.
Next, went to South Philadelphia to one of Mosaic’s Indonesian churches, the Philadelphia Praise Center (PPC), pastored by Aldo Siahaan. There we were blessed by a delicious homemade Indonesian lunch while we heard from a couple of Everence representatives about the financial resources available to Mosaic pastors. Following, Pastor Aldo told us about PPC’s incredible history. Learning about PPC provided a glimpse of the type of conference Mosaic strives to be.

Following our time at PPC, we had dinner at a Mexican restaurant with the pastor of Centro de Alabanza de Filadelfia, a Spanish-speaking church that originally began with PPC but now worships in its own space.
At the Mosaic Offices in Landsdale, Stephen Kriss continued to teach us about Anabaptist history and the “polygenesis” theory of their origination. This is the idea that Anabaptism emerged in multiple places through shared commitments to believers’ baptism, discipleship, and nonviolence. Then, over a lunch of phenomenal Indian food, we heard from Ertell Wigham, the former pastor of Nueva Vida Norristown New Life, a bilingual, multiracial church. Despite their many differences, this community has continued to work towards unity and interculturalism; their church is such a powerful example of the body of Christ!
From the Mosaic offices, we made our way to FernRock Retreat, a beautiful place surrounded by nature and intentional opportunities for connecting with God, operated by Mosaic Pastor Sandy Drescher-Lehman and her husband, John. I spent over an hour walking and observing God’s beautiful creation, talking to Him out loud without any expectations or fear. After learning, thinking, and discussing almost non-stop for three days, this was a welcome breath of air. I am so grateful that Mosaic values sabbath time and understands how important quiet and rest are, not just learning. What a gift!
I confess that at first, I was not looking forward to this course. I had already taken Anabaptist history in seminary, so I did not see the usefulness in learning it again. Yes, I would get to meet new pastors, but I did not see the point of building relationships with pastors from all over the country that I would likely not see again. However, God humbled me quickly. I was moved by learning everyone’s stories. These stories, mixed with learning about the history of my ancestors, made it all come to life in a deeply personal and impactful way that I had never experienced before.
I began to see how my story as a Christian, as a woman, as a Mennonite, and as a member of Neffsville (PA) Mennonite fits into the larger story of God’s people. I was struck with a deep sense of God moving and speaking within me about my future and the future of Neffsville. Coming to the end of this course, I still have much to learn, but in the meantime, I am certain that I am exactly where God wants me to be. I am grateful to Mosaic for this experience and its continued support.
