World Mission Society Church of God in Santee occupies a worship center at 9230 Prospect Avenue on the Woodside-Prospect industrial corridor. The congregation observes Saturday Sabbath worship and the biblical feasts outlined in the New Covenant — including Passover, the Feast of Tabernacles, and the Day of Atonement — a liturgical calendar distinct from Sunday-centered traditions, complemented by weekday volunteer initiatives that engage local youth through organizations like the Santee Teen Center on Arlette Street. Community service constitutes a core institutional mission, with organized blood drives, environmental clean-up campaigns, and disaster-relief coordination earning the congregation a Presidential Volunteer Service Award. The Santee location is one of two San Diego County campuses and part of an international network of congregations, with worship services on Saturdays and Tuesdays adjusting seasonally between summer and winter schedules alongside community event partnerships coordinated with the Santee Farmers Market on Carlton Hills Boulevard. Worship services incorporate New Covenant sacraments including foot-washing ceremonies and unleavened bread communion observed on the biblical Passover date rather than a fixed Sunday schedule.
