Established in 1915, St Peter's Catholic Church is one of the oldest and largest Catholic churches in Dixon, serving more than 700 families. Aside from its masses, which are held in English and Spanish, the church recognizes and celebrates several important Catholic holidays such as Virgin of Guadalupe Day, Christmas and Easter. It also hosts weddings, baptisms and confirmations.
The church has a youth ministry group and a missionary group that travels as far away as Peru for missionary work. St. Peter's is part of the Diocese of Sacramento and welcomes anyone who would like to worship.
