St. Sebastian Catholic Church

About this church

St. Sebastian Catholic Church celebrates Sunday Mass at 7, 9, and 11 a.m. at 373 Bon Air Road in Greenbrae. Daily Mass begins at 7 a.m., after which the church remains open until noon. Reconciliation is available from 3 to 4:30 p.m. Saturday and from 7 to 8 Wednesday, as well as by appointment. The parish presents prayer as public or personal, spoken or silent, with sung Psalms forming part of Catholic worship.

The Eucharist and the other sacraments organize the parish's liturgical life, while ministries connect faith with food, fellowship, and service. Readers proclaim Scripture at Mass, finance volunteers advise parish leadership, and other teams support worship and community needs. A recurring fellowship-and-service gathering meets at 9:30 on the second Saturday of every other month, though the bulletin should be checked for the active date. St. Sebastian describes itself as a welcoming Catholic community called to live Christ's message through love and service, support personal and communal prayer, and deepen sacramental life. A newcomer has three Sunday options, while someone seeking a quieter weekday visit can attend 7 a.m. Mass and remain for prayer before noon. Confession seekers should use the published Saturday or Wednesday window but confirm holiday and holy-day changes in the bulletin.
