Iglesia Hispana de Tri-City in Carlsbad is the Spanish-language ministry arm of Tri-City Bible Church, gathering on Marron Road in the 92008 zip code between Carlsbad Village and Tamarack Beach. The congregation delivers verse-by-verse expository preaching entirely in Spanish, a hermeneutic approach grounded in the same Reformed evangelical theology that shapes the bilingual parish life at St. Patrick Catholic Church on nearby Adams Street. Weekly sermon audio archives on Spotify under the IHTC podcast feed allow congregants to revisit each passage study between gatherings. The ministry operates under the doctrinal oversight and elder board of the Vista-based parent church, extending that campus's Bible-education mission into Carlsbad's North County Hispanic community through the same Marron Road corridor served by MAAC - Laurel Tree Center's family-support programs. The stated mission—presentar creyentes maduros en Cristo—centers every sermon series on producing spiritually mature believers through systematic Scripture exposition rather than topical rotation.
