As a reminder, Bishop Vann, as shepherd of our Diocese of Orange, has dispensed the Catholic faithful of our diocese from the obligation of attending Sunday Mass during this time of the health pandemic. However, the obligation to “keep holy the sabbath day” cannot be dispensed since it is divine law. Hence, those who do not or cannot attend Sunday Mass for whatever reason are still obligated to pray or worship God on Sunday in whatever way possible. Viewing Mass online and making the Act of Spiritual Communion is one of many options.

Act of Spiritual Communion

My Jesus, I believe that Youare present in the Most Holy Sacrament. I love You above all things, and I desire to receive You into my soul. Since I cannot at this momentreceive You sacramentally,come at least spiritually into my heart.I embrace You as if You were already thereand unite myself wholly to You.Never permit me to be separated from You.Amen.

St. Alphonsus De Liguori


Fridays: 9:00 a.m. to noon on the church patio

O Most Holy Trinity, I adore You! My God, my God, I love You in the Most Blessed Sacrament.

Eucharistic Prayer from Fatima

Act of Contrition

“O my God, I am heartily sorry for having offended thee, and I detest all my sins because I dread the loss of heaven and the pains of hell; but most of all because they have offended thee, my God, who art all good and deserving of all my love. I firmly resolve, with the help of thy grace, to confess my sins, to do penance, and to amend my life.”



Since time immemorial singing and chanting has been part of our worship of God. The Bible tells us that even the angels sing as they announce the birth of our Lord Jesus to the simple shepherds. Whether our hearts are burdened by sorrow or bursting with joy, we sing. To give God fitting honor and sing well, it requires hard work, great effort and talent. This is why Saint Augustine says “to sing is to pray twice.” 

Unfortunately due to the COVID-19 health pandemic, you are asked to refrain from singing out loud at Mass for the time being, in order to reduce the spread of this disease. This drastic measure is taken out of an abundance of caution to protect the health of those who come to Mass, since COVID-19 typically spreads through respiratory droplets from coughing, sneezing, or talking. Everyone who attends Mass is already required to wear a face mask which acts as another level of protection.

Thus, starting the weekend of July 11-12, we will discontinue the printing of the lyrics for the hymns of our Sunday Mass in the parish bulletin and we will not post them on our website either. The cantors, however, will continue to sing at our weekend Masses and all of us are invited to sing along SILENTLY in our hearts. 

Thank you for your understanding, cooperation and patience as we deal with this horrible disease together.
