COVID-19 Reminders

Seating inside the church and in the courtyard:

Seating in the courtyard is available for all Masses; and seating inside the church is available for most Masses.  All Masses from Monday through Saturday are celebrated in the church with seating inside the church and in the courtyard.  In addition, the 11:00 a.m. and 5:30 p.m. Sunday Masses are livestreamed from the church with seating inside the church and in the courtyard.  The other Sunday Masses (at 7:00 a.m., 9:00 a.m., and 1:00 p.m.) are celebrated in the courtyard with seating only in the courtyard.

No reservations or tickets are needed to sit in the church or the courtyard.  All seating is on a first-come, first-serve basis.  Because seating inside the church is limited, latecomers (particularly on Sundays) may have to sit in the courtyard.

Strict social distancing

Strict social distancing is required in the courtyard and inside the church.  Specifically, people must wear a face covering and maintain social distancing at all times (i.e., at least six feet of separation between people from different households, although people from the same household may sit together). 

The chairs in the courtyard are spaced at least six feet apart; and the available pews in the church are also at least six feet apart.  The chairs and the available pews are cleaned after every Mass.

Inside the church, people should sit only in the available pews, not in the pews that are blocked off by tape.  Because the available pews are at least six feet apart, ideally each household will sit in its own pew.  If two households share a pew, there should be at least two empty seats (i.e., at six feet) between the two households.

Sitting in the courtyard

Tents in the courtyard provide shade and protection for about 80% of the chairs.  Those sitting in the courtyard may want to wear a sunhat, sunglasses, and sunblock and bring an umbrella and a water bottle.  For cold days, we recommend wearing a coat, gloves, a scarf, and hat.  People may also bring their own chairs or seat cushions.

Confessions in the courtyard:

Monday through Saturday:  After the 8:00 a.m. Mass 
Friday:             5:00-6:00 p.m.
Saturday:         3:00-4:30 p.m.  

You may schedule confession with a priest at another time by calling the Pastoral Office (909-861-7106).

Blessed Sacrament Chapel hours: 

Monday through Thursday:    8:30-9:30 a.m.
                                           4:15-6:15 p.m. 
Friday:             4:15-6:15 p.m.
Saturday:         8:30-9:30 a.m.

Enter the chapel through the open door that faces the church’s lower parking lot.  People need to maintain strict social distancing of at least six feet and wear face coverings.  Seating is limited to nine people. 

Holy Hour and Eucharistic Exposition and Adoration in the church
(with seating inside the church and in the courtyard) 

Friday:             8:30-9:30 a.m.  Eucharistic Exposition and Adoration
                       7:45-8:45 p.m.  Holy Hour (a worship aid will be posted here)

Archbishop José Gomez invites every Catholic to make his or her commitment for 2020 to Together in Mission, which provides financial assistance to 67 poor parishes and 74 poor Catholic schools in the Los Angeles Archdiocese. 

This year, our parish has been asked to raise $129,494.  Last year, 488 parish donors helped us to raise $142,003; and we exceeded our goal for the first time in several years.  We sincerely thank everyone who contributed last year and who will contribute this year to Together in Mission.  

This year’s theme “Our Story is Alive” reminds us that our gifts to Together in Mission are an active demonstration of our faith and love for those in our Archdiocese who need our support.  Please make a pledge with the information that was mailed to your home, the pledge envelopes that are available in the pews, online at, or by calling 213-637-7672.

When making a pledge, please indicate that St. Denis is your parish so that your pledge and donations will count toward St. Denis's 2020 goal.

Your gifts to Together in Mission ensure that every Catholic living in the Archdiocese has a parish to celebrate their faith and access to a Catholic school education.  You are living your faith through your actions when you support Together in Mission. 

Thank you for your generosity.

Again, the website for Together in Mission is; and please do not forget to select St Denis as your parish.
