Jack Baca was born and reared in Socorro, a small town south of Albuquerque, New Mexico. He received his bachelor's degree from the University of New Mexico (history major) in 1978, and his Master of Divinity (preaching concentration) from Princeton Theological Seminary in 1982. He received his Doctor of Ministry degree at Fuller Theological Seminary.

Jack's first call to ministry was as associate pastor of Woodhaven Presbyterian Church in Irving, Texas. From there he became an associate at First Presbyterian Church in Albuquerque, and then senior pastor of Trinity Presbyterian Church in Tucson, Arizona. In September of 1998, Jack assumed the senior pastorate of the Village Church.

In addition to his experience with the local church, he has served on numerous presbytery and synod committees, as a national board member and vice-president of Presbyterians for Renewal, and as a commissioner and committee moderator at the 205th General Assembly of the Presbyterian Church (U.S.A.)
