Brock grew up in Fairfield and was part of the first integrated class at Fairfield High School. He transferred briefly to Ensley High School during his sophomore year, but returned to graduate with his class at Fairfield. He went on to complete a bachelor's degree at Birmingham-Southern College and a master's in divinity at Vanderbilt University in Nashville, Tennessee.
In the early 1980s, Brock served as a minister in the North Alabama Conference of the United Methodist Church, but eventually came into conflict with the denomination's growing conservatism. He left the pulpit and worked as for the securities firm Dean Witter in Colorado.
There Brock became involved in the Unitarian church and was ordained a minister in that denomination and also completed a doctorate in ministry from Wisdom University in Oakland, California. He led a church in Jacksonville, Florida from 1989 to 1997, then an interim position in Daytona, Florida, before leading another congregation in Edmonds, Washington from 1999 to 2007. After that he worked as a consultant to churches and as an interim minister. He also became a licensed therapist in Washington.
