Our Mission

Welcoming all, we, the Spirit filled parish of St. Thomas More value our Roman Catholic faith by celebrating the sacraments, breaking open the Scriptures, and joyfully offering ourselves in service to others. Under the inspiration of our Patron saint, we seek to build a caring community that embraces the values he modeled of friendship, integrity and courageous love of God.

In conjunction with the directive from the Governor of California and the Diocese of Orange, Masses will be held outside until further notice.  Livestream Masses will continue and the Eucharist will be distributed to those outside at the end of Mass.  If you are able, bring your own chair and pad to kneel on, if desired. 

We ask for your cooperation and patience as we navigate the directives in response to the pandemic. Even during these challenging times, we continue to worship our Lord as a faith-filled community.

“Drive-up” Confessions with Fr. Kiet Ta and Fr. Joseph Horn continue from Noon to 2:00 pm every Saturday.  Cars will simply line up in the parking lot and wait for their turn.  When it is your turn, then you will get out of your car and sit in the chair outside the priest’s open window.  The screen and shade will provide a barrier.
