Rev. Philip Merten

Rev. Philip Merten

Chaplain

Email

Phil became a volunteer Bible study leader for Institutional Ministries while he was a seminary student and then officially joined the staff as a chaplain in 1989. Most of his chaplaincy work has been with people who’ve gotten trapped in addictions and chemical abuse. That work includes holding Bible discussion groups with people who are incarcerated as well as with people who are out of prison and want to stay that way. (One of his groups presented him with a stole to wear with his alb for preaching – the stole is decorated with the faces of children of all tribes and nations, and the recovering addicts who gave it to him said, “Those are us.”)
