Elder Barclay was ordained in 1992 with the United Pentecostal Council of the Assemblies of God, Inc (UPCAG). He served several years as the National Youth Director. He credits much of his spiritual development to his parents, the late Bishop Fitz and Mother Geraldine Barclay.

In 1995, Elder Barclay succeeded his father as Senior Pastor of Progressive. Right away, God called him to move outside the church walls to reach people in the streets.  In 1999, God directed him to full-time pastoral ministry, and called him to move outside the church walls to reach people in the streets. His focus continues to be on evangelizing individuals who battle problems such as life-controlling substances abuse, prostitution, alcoholism and homelessness. 

In 2009, Elder Barclay was elected as the International Presiding Elder of the United Pentecostal Council of the Assemblies of God, Inc. (UPCAG). Under his leadership, through his obedience to the voice of the Lord, the Council has experienced monumental expansion. His profound impact on the organization led to his reelection in 2015.
