For Reformed worship in Alpine, Pilgrim Presbyterian Church gathers at 2225 West Victoria Drive under the oversight of the Presbytery of Southern California. The congregation meets inside Alpine Community Church, a shared-use campus on Victoria Drive that houses multiple faith communities serving the 91901 area. Worship follows a structured liturgical order that includes Scripture readings, congregational psalm-singing, expository preaching, and the administration of the sacraments, with both a morning and an evening Lord's Day gathering. The evening service provides a second weekly opportunity for verse-by-verse teaching, a format less common among East County San Diego churches. Campus-sharing also connects Pilgrim's families with Little Pioneers Preschool, which operates early-childhood education on the same Victoria Drive property. Affiliated with the Orthodox Presbyterian Church, the congregation confesses the Westminster Standards and subscribes to the OPC's Book of Church Order for its session governance and disciplinary framework.
