Pastor & Staff

James Madden


Rev. James Madden is the rector and co-church planter of St. Luke Medical District. He is ordained as a priest in the Anglican Church in North America (ACNA). Previously an ordained minister in the Presbyterian Church in America (PCA), James has a heart for ecumenical church partnership across denominations for the expansion of God’s kingdom. That is what drew him to the ACNA diocese, Churches for the Sake of Others (C4SO).

During the COVID-19 pandemic, James and his wife Happy launched an outdoor worship service for friends and neighbors to gather safely while churches were closed. As enthusiasm and attendance grew, James discerned a call to church plant in Dallas. He developed a love for the Medical District, a neighborhood with world-renowned medical institutions and very few churches. Before planting St. Luke Medical District, James served as the Campus Minister for Reformed University Fellowship (RUF) at Southern Methodist University from 2014-2021. He was also an RUF intern at Wake Forest University from 2008-2010. Through the work of college ministry, James experienced the deep joy of ministering to young adults from a wide range of spiritual backgrounds.

James holds a B.A. in Spanish and History from Washington and Lee University, where he also played baseball. He received his Master of Divinity from Redeemer Seminary in 2014. A Dallas native, he is married to his best friend, Happy, and actively reads theology and philosophy, while following news and politics. He is also a coffee enthusiast, so don’t hesitate to stop by his office and have a pour-over with him.
