Otay Apostolic Church in Chula Vista serves a Spanish-speaking congregation on Tremont Street under the Apostolic Assembly of the Faith in Christ Jesus denomination. The church's community ministry extends beyond worship into family-support initiatives, complementing the social-service programming offered by South Bay Community Services in the 91911 area. Services are conducted entirely in Spanish, with dynamic worship sets and practical sermon teaching rooted in the Pentecostal apostolic tradition that traces to the 1904 Welsh Revival. A children's program runs concurrently with the main service, offering age-graded biblical instruction that parallels the early-education approach at Children's Choice Academy in the local childcare network. The Tremont Street facility includes a main worship hall with a raised platform stage, a full-band sound system, and a separate classroom wing dedicated to youth catechesis and leadership development.
