At The Church of God of the Union Assembly at Knoxville, we proudly celebrate over one hundred years of holiness preaching by faithful men of God.  As part of an Assembly founded on God's word, Knoxville has proved dedicated to reaching the world and serving God's people. As guardians of the gospel, we are committed to the cause of Jesus Christ through the mission of His church. 


The mission of the The Church of God of the Union Assembly, Inc. is as follows:


We will preach tirelessly the everlasting, life-changing gospel of Jesus Christ as the only hope for eternal life.


We will teach by our words and actions, those who will see and hear, the precepts and principles in God's word that will equip the hearer to live godly, productive lives so that they may bring honor to Christ and His church.


We will reach with every resource, to those believers whose faith is weak, whose spirit is tired, and whose light has grown dim. 


Knoxville is led by our Pastor, Assistant Pastor, and a team of dedicated preachers and staff. 




Pastor Marcus Sisk was born in Chatsworth, Georgia, and raised in the Southeast region of the United States as his father (and hero) faithfully served in the ministry.  Marcus was ordained April 20, 1989, in Dalton, Georgia, and followed in his father's footsteps as he traveled and served as a devoted Youth Pastor and Assistant Pastor at several churches throughout Alabama, Arkansas, Florida, and Georgia from 1990-2021. He was recently placed as Pastor at The Church of God of the Union Assembly at Knoxville on January 29, 2023. Marcus married his wife, Jessica, in 2009, and together, they have 3 children and 4 grandchildren. Some of his greatest influences throughout life were his father, Kenneth Sisk, as well as Brothers Phillips Gentry, Jack Giles, Paul Hughes, and Dennis Smith. His desire is to see the Church grow through the preached word, building strong relationships and programs, and community outreach. 



Assistant Pastor Allen Massengill was born and raised in Knoxville, Tennessee, and has served as Assistant Pastor at The Church of God of the Union Assembly at Knoxville since July 2020. He was blessed to grow up in a religious home, and at 13-years old, felt the call on his life to serve in the ministry. At an early age of 14-years old, Allen was ordained as a bishop on March 21, 1971, in Dalton, Georgia. In 1980, he married his wife, Trish. Throughout the years, he has faithfully served The Church of God of the Union Assembly in many different states. Allen's greatest influence throughout life was Brother Charlie T. Pratt, III. His desire for the Church is to see it grow in unity and to see the lives of God's people changed forever.




Knoxville believes that we are better together. Our staff is pleased to serve God, His people, and each other.
