Iglesia Ni Cristo in Chula Vista is the San Diego County locale of the Philippine-founded Christian denomination established by Félix Manalo in 1914, now spanning more than 7,000 congregations across over 100 countries. The Rios Avenue chapel serves multiple locale congregations — including Eastlake, Palomar, Duncan Ranch Tagalog, and Rolling Hills Spanish — and its youth outreach coordinates volunteer service projects with organizations such as South Bay Youth Center. Worship follows the INC's distinctive nontrinitarian theology and restorationist liturgical order, featuring congregational hymns, Scripture exposition by an ordained minister, and structured prayer led from the pulpit. Midweek worship services run on Wednesday evenings, with a separate Saturday gathering and an early-morning Sunday service completing the three-session weekly cycle. Large-scale congregational events and regional worship gatherings for the San Diego County district rotate among rented venues such as Swiss Park & Hall San Diego when attendance exceeds the Rios Avenue chapel's seated capacity. The 1820 Rios Avenue chapel features the denomination's signature steep-gable architectural profile with a nave seating approximately 200 worshippers, a raised central pulpit, and an interior finished in the INC's standard white-and-blue color scheme.
