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.

Orange County has moved from purple to red on the state’s COVID-19 tier ranking, allowing for limited indoor worship. However the Diocese of Orange will continue to celebrate Sunday Mass (and vigil Masses) outside to accommodate the larger crowds. Weekday Masses may be celebrated indoors with 100 people or less, or 25 percent of capacity. Based on our attendance, STM weekday Masses will be held outdoors. Baptisms, weddings and funeral Masses may be held indoors with 100 people or less attending.
In-person gatherings of prayer groups, bible studies, Ministry meetings, etc. are not presently allowed.
Dispensation from attending Sunday Mass has been revised – If you fall into one or more of these categories, you are not obligated but always welcome to attend Mass in person:
  • If you are over 65
  •  If you have an underlying health condition
  •  If you think you are sick, especially if you think you may have COVID-19
  •  If you are truly afraid of catching the virus
The Blessed Sacrament Chapel is open for private, individual prayer Mon-Fri from 9:00am to 2:00pm. Please remember to keep a six foot physical distance, sanitize upon entrance/exit and please wear a face covering.
Please know that we have all possible safety measures in place and look forward to seeing you all back at St. Thomas More.
