Holy Cross Episcopal Church in Carlsbad's La Costa Heights neighborhood is an Episcopal Diocese of San Diego mission congregation that held its first worship service on November 30, 1986. The congregation shares its 7805 Centella Street worship space with Jewish Collaborative of San Diego, a building-share partnership launched in 2022 that extends an earlier interfaith model Holy Cross practiced with Congregation B'nai Tikvah at a previous Bressi Ranch location. Planted by St. Michael's by-the-Sea as a mission in the mid-1980s, the parish moved through a community center, a storefront, and an industrial-park facility near Palomar Airport before settling into the La Costa Heights space near Batiquitos Lagoon. The "Open Minds, Open Arms" mission statement frames an inclusive Episcopal community operating Bible study groups, Godly Play children's programming, a Sacred Ground racial-reconciliation series, and an LGBTQ+ fellowship. Outreach ministry extends into end-of-life pastoral care through networks that include Hospice of the North Coast, reflecting the parish's emphasis on serving south Carlsbad's aging and homebound residents. Holy Cross operates under the governance of the Episcopal Diocese of San Diego within the worldwide Anglican Communion, following the Book of Common Prayer liturgical tradition that structures its weekly Eucharist and seasonal rites.
