Christian Parenting Course
(via Zoom)


St. Denis is starting a new Christian Parenting Course to help parents raise their children in this challenging, secularized world.  The Christian Parenting Course will be led by our deacon couple, Dennis and Christina Shin, who have two adult daughters.  Participants will meet via Zoom for nine weeks on Wednesday evenings from 7:30-9:00 p.m. from April 28 through June 23.  The Zoom link for all of these Wednesday meetings will be:

The Course will be based on FamilyLife’s “Art of Parenting,” which teaches parents: 
            (1)  how to deal with the real-world challenges of raising children today; and
            (2)  how to make faith the core of their parenting.

Each participant will receive a free workbook; and each meeting will include prayer, a relevant and entertaining video (20-30 minutes), short workbook exercises, and small-group discussions.

Couples (fathers and mothers) are encouraged to take the course together so that, together, they can put into practice what they have learned.  Single parents also are welcome; and a father or mother can take the Course even if his or her spouse (or significant other) does not take the Course.  Those who will take the Course by themselves may want to invite a friend who is a parent to take the Course with you.  Then, you and your friend can compare notes and support each other as you put into practice, with your respective families, what you have learned.

For further information and to sign up to receive your workbook, please send your mobile phone number and E-mail address to Deacon Dennis at this address:  You also can call the Pastoral Office at (909) 861-7106 for more information.


Movie for the Christian Parenting Course


The movie, Like Arrows, is a thought-provoking, emotional story about the realities of parenting today.  It’s also an important and necessary introduction to our Christian Parenting Course.  (A trailer for the movie is available here.) 

The movie is available on Netflix, Amazon Prime Video, and YouTube.  In addition, those who participate in our Christian Parenting Course will be able to watch the movie for free.

Stations of the Resurrection



Every Sunday from April 11 through May 23 (Pentecost), we will pray the Stations of Resurrection at 12:00 noon.  The Stations of the Resurrection are similar to the Stations of the Cross, but they focus on Jesus’s Resurrection appearances as well as his Ascension into heaven and his sending of the Holy Spirit at Pentecost.  The Stations of Resurrection, which also will be livestreamed, are intended to help us to reflect more deeply and prayerfully on Jesus’s Resurrection.  Please join us every Sunday either in person or via our livestream.

For more information about the Stations of the Resurrection, please see this Catholic New Agency article and this Wikipedia article.

"Permission to podcast/stream the music in these services is obtained from ONE LICENSE with license #A730717. All rights reserved.”

No one is obliged to attend Mass on Sundays or Holy Days of Obligation because Archbishop José Gomez has indefinitely dispensed everyone in the Archdiocese of Los Angeles from this obligation for the duration of the pandemic.

COVID-19 Reminders

Seating inside the church and in the courtyard:

The available seating in the church has been reconfigured to allow more people to sit inside when we celebrate Mass and other liturgies.  Therefore, all of our Masses (including all Sunday Masses) are being celebrated inside the church, with overflow seating in the courtyard.  

Of course, because of the pandemic, seating inside the church is still limited.  Thus, if you want to sit inside the church, please arrive early for Mass (especially Sunday Masses).

Seats are available in the courtyard for all Masses and other liturgies.  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.

No reservations or tickets are needed to sit in the church or the courtyard.  All seating is on a first-come, first-serve basis.

Strict social distancing

Strict social distancing is required inside the church and in the courtyard.  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). 

Confessions in the courtyard:

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

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

If you cannot go to a priest for Confession during this pandemic, Pope Francis encourages you to confess your sins directly to God and make an “Act of Perfect Contrition”:

“If you don’t find a priest to go to confession, speak to God.  He’s your Father.  Tell Him the truth. ‘Lord. I did this and this and this.  Pardon me.’  Ask His forgiveness with all your heart, with an act of contrition, and promise Him, ‘Afterward I will go to confession.’  You will return to God's grace immediately.”  (This quotation is by Pope Francis and is from this article.)

Here is another article with more information about how to make an “Act of Perfect Contrition.”

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.

Vatican:  COVID-19 vaccines are “morally acceptable”

Archdiocese of Los Angeles:  “Strongly encourages” Catholics
to receive a safe and effective COVID-19 vaccine

The Vatican’s doctrinal office, the Congregation for the Doctrine of the Faith (CDF), has determined that it is “morally acceptable” for Catholics to receive the vaccines against the COVID-19 virus.  This judgment is deeply rooted in the Catholic moral tradition.

On December 21, 2020, the CDF stated:

All vaccinations recognized as clinically safe and effective can be used in good conscience with the certain knowledge that the use of such vaccines does not constitute formal cooperation with the abortion from which the cells used in production of the vaccines derive . . . the morality of vaccination depends not only on the duty to protect one's own health, but also on the duty to pursue the common good.

In the absence of other means to stop or even prevent the epidemic, the common good may recommend vaccination, especially to protect the weakest and most exposed.

Therefore, the Archdiocese of Los Angeles strongly encourages Catholics to receive a safe and effective COVID-19 vaccine for the sake of ourselves, our loved ones, and the common good.

If some of the faithful do not receive the vaccine, the Vatican says that those persons “must do their utmost to avoid . . . becoming vehicles for the transmission of the infectious agent.”

For more information, please see the following documents from the U.S. Conference of Catholic Bishops (USCCB):

USCCB – U.S. Bishop Chairmen for Pro-Life and Doctrine

USCCB – Moral Considerations Regarding the New COVID 19 Vaccines

USCCB – Answers to Key Ethical Questions About COVID 19 Vaccines

USCCB – Moral Guidance on Vaccine

USCCB – Statement on the Johnson & Johnson COVID-19 vaccine

Please also watch the following webinar:

Webinar - “Love Your Neighbor and Get Vaccinated:  Science, Ethics and the COVID-19 Vaccines” 

The one-hour-long webinar discusses the safety and efficacy of the COVID-19 vaccines, as well as the impact the pandemic has had on parishes around the state.  If features Dr. Charles Binkley, MD, Director of Bioethics, Markkula Center for Applied Ethics at Santa Clara University; Fr. Luke Dysinger, OSB, MD, DPhil., Professor of Church History and Moral Theology, St. John's Seminary; and Mr. Isaac Cuevas, Director of Immigration and Public Affairs, Archdiocese of Los Angeles.
