Dedicated to bringing about justice to Pennsylvania

Bishop Dwayne Royster | Executive Director

Bishop Dwayne D. Royster, a leading voice in modern faith-based activism, wants to change the world. Whether he is serving as a pastor, challenging the status quo as a political activist, educating and empowering communities as a radio show host, or encouraging and inspiring audiences around the country as a writer and public speaker, Bishop Royster’s work is fueled by deep faith and passionate commitment to bringing about social justice.

Bishop Royster has served in pastoral ministry for the past over 26 years in a variety of positions and denominations. Driven by his deep commitment to the four biblical principles of redemption, restoration, renewal and refreshment, Bishop Royster works diligently to meet people where they are and instill in the congregation a need to be like Christ: slow to judge always ready to offer grace and mercy.

Bishop Royster currently serves as Senior Pastor of Faith United Church of Christ in the North Michigan Park Section of Washington, DC. Bishop Royster is an advocate for preparing congregations for the ministry of availability. Prior to his current role as Senior Pastor, Bishop Royster has had the honor of presiding over the Living Water United Church of Christ (Founder and Senior Pastor); Mid-Town Parish UMC (Pastor); Way of Life Ministries Mennonite Church (Church Planter and Pastor); Harold O.

In addition to his pastoral responsibilities, Bishop Royster is the General Secretary of Higher Ground Christian Fellowship International and serves on the College of Bishops.

Bishop Royster has extensive organizing, advocacy, political and faith leadership experience.
