help for those who are mourning
the death of a loved one

If you’ve lost a spouse, a child, a family member, or a friend, you’ve probably found that there are not many people who understand the deep hurt you feel.  This can be a confusing time, when you feel isolated and have many questions about things that you’ve never faced before.

Starting on Sunday, July 25, St. Denis’s GriefShare support group will meet weekly to help participants face these challenges and move toward rebuilding their lives.  The group will meet every Sunday from 1:00-3:00 p.m. in Room A in the Hall for 13 weeks with a different topic for each session, as set forth below.


July 25, 2021               Session One:  “Is This Normal?”
August 1, 2021            Session Two:  “Challenges of Grief”
August 8, 2021            Session Three:  “The Journey of Grief (Part One)”
August 15, 2021          Session Four:  “The Journey of Grief (Part Two)”
August 22, 2021          Session Five:  “Grief and Your Relationships”
August 29, 2021          Session Six:  “Why?”
September 5, 2021      Session Seven:  “Guilt and Anger”
September 12, 2021    Session Eight:  “Complicating Factors”
September 19, 2021    Session Nine:  “Stuck”
September 26, 2021    Session Ten:  “Lessons of Grief (Part One)”
October 3, 2021          Session Eleven:  “Lessons of Grief (Part Two)”
October 10, 2021        Session Twelve:  “Heaven”
October 17, 2021        Session Thirteen:  “What Do I Live For Now?”

Each GriefShare session will have three distinct parts: 

(1)  watching a video seminar featuring top experts on grief and recovery;
(2)  discussing with the group what was presented in the video and what is going on in their lives; and
(3)  discussing questions and comments from a workbook, which participants will use during the week for further study of the grieving process and for journaling about their emotions.

Just show up for one of the sessions.  You don’t have to sign up in advance.

Consecration to St. Joseph

September 30 – November 6

In a recent Apostolic Letter, Pope Francis proclaimed this year as the Year of St. Joseph to mark the 150th anniversary of the proclamation of St Joseph as Patron of the Universal Church.  In the Letter, Pope Francis described St. Joseph as a beloved father; a tender and loving father; an obedient father; an accepting father; a father who is creatively courageous; a working father; a father in the shadows; a father to Jesus; and a father for us.

To mark this Year of St. Joseph, Deacon Al will lead parishioners in 33 days of prayer and preparation, leading to their consecration to St. Joseph on Saturday, November 6 at 8:30 a.m.  During the 33 days of preparation, Deacon Al and parishioners will meet every Thursday from 7:30-8:30 p.m. from September 30th through November 4th.  Participants can attend the meetings either in person (in the church) or via Zoom.  The Zoom link for all of the meetings will be:

To prepare parishioners for their consecration, Deacon Al will use the following book:  Consecration to St. Joseph:  The Wonders of Our Spiritual Father by Fr. Donald H. Calloway.  You will need this book to participate fully in the 33 days of preparation.  The book is widely available—e.g., on (for $13.39), on Kindle (for $9.95), on Audiobook (for free with an Audible trial), and elsewhere.  The Pastoral Office has about 20 copies of the book; and they are available for $11.00.  For more information, please contact the Pastoral Office at (909) 861-7106.   

For an overview of the book by the author, please watch this video:

Together in Mission


This month, Archbishop José Gomez invites every Catholic to make a commitment to Together in Mission for 2021. 

Last year, Together in Mission raised $14 million, which was distributed to 67 poor parishes and 74 poor Catholic schools throughout the Los Angeles Archdiocese.  The poor parishes and schools used the money for educational programs, emergency projects, operational support, service to the poor, and outreach programs.

This year’s theme is “Forward with Faith.”  Our financially struggling parishes and schools were severely impacted by COVID-19.  As we emerge as one Catholic family from this pandemic, the call to help those in need is deeper and louder.

The archdiocese’s goal for Together in Mission this year is $15.35 million; and St. Denis has been asked to raise $114,875.  Last year, we exceeded our parish’s goal despite the pandemic; and we sincerely thank everyone who contributed last year and who will contribute this year to Together in Mission.

You do not have to donate any money now.  Instead, we are asking every household and family to make a new pledge this year to Together in Mission.  You can then take the rest of the year to fulfill your pledge. 

You may make a pledge in any of the following ways:
(1)  with the information that was mailed to your home;
(2)  with the pledge envelopes that are available in the pews and in the vestibule of the church;
(3)  visiting;
(4)  calling 213-637-7672 (Monday-Friday, 8 a.m. – 5 p.m.);
(5)  texting Forward21 to 213-397-0682.

However you make your pledge, please be sure to identify St. Denis Parish as your parish so that St. Denis will be credited with your pledge and donation.

Thank you for supporting Together in Mission.

Obligation to attend Masses on Sundays and Holy Days of Obligation

With the reopening of California in the wake of the pandemic, Archbishop José Gomez has reinstituted the obligation for Catholics to attend Mass in person on Sundays and Holy Days of Obligation. 

However, those who have serious and legitimate reasons (e.g., illness; underlying health conditions that render them susceptible to illness; significant fears of becoming ill; etc.) are dispensed from this obligation (and, thus, are not obliged to attend Mass in person). 

Please note that watching a livestreamed Mass does not fulfill the obligation to attend Mass in person.  However, if you are unable to attend Mass in person, we encourage you to participate in our livestreamed Masses.  We livestream one or two Masses every day simultaneously to our YouTube channel and Facebook page

COVID-19 Reminders

Seating inside the church and in the courtyard

On June 15, 2021, we changed the seating inside the church so that more than half of the pews have normal seating, the way we used to prior to the pandemic.  However, we also have four pew sections on the sides reserved for socially distanced seating because we know that children under 12 are not vaccinated and that others are not fully vaccinated for various reasons.  In addition, we have socially distanced seating in our courtyard for those who prefer not to sit inside the church.

In accordance with the latest order by the L.A. County Department of Public Health, all people (age 2+) inside the church, the Pastoral Office, and the Hall need to wear a face covering.

For now, Holy Communion will be offered only in the form of bread.  To prevent the spread of germs, Communion on the hand is strongly encouraged.


Monday through Saturday:  After the 8:00 a.m. Mass in the courtyard
Friday:             5:00-6:00 p.m. in the church*
Saturday:         3:00-4:30 p.m. in the church* 
*Fr. Dennis will be in the back pew of the church; Fr. John will be in his confessional booth.

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.”

Sunday: 6:30 a.m. – 7:30 p.m.

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.
