Bilingual Christian worship in English and Spanish at Grossmont Center defines ONE Church, a unity-focused congregation meeting in La Mesa's Building L at 5500 Grossmont Center Drive. The church's family-ministry programming serves multilingual households across the 91941 and 91942 ZIPs, addressing early-childhood faith formation in the same developmental space served by Learning Jungle La Mesa for structured preschool education. A Thursday evening gathering complements the full Sunday schedule, building midweek community around small-group study and prayer. The bilingual worship format incorporates a culturally diverse music ministry and community-meal fellowship, large-group event hospitality also handled by Da Kine's Hawaiian Catering for celebrations across La Mesa. The Grossmont Center campus positions the church at the intersection of Grossmont Center Drive and Murray Drive, providing a central gathering point for east San Diego County's growing bilingual Christian community.
