“Trunk or Treat”

Saturday, October 31 from 2:00-4:00 p.m.
in the lower parking lot

Parents, bring your children (recommended ages 12 and under) dressed in costumes to St. Denis for “Trunk or Treat.”  You can park in an upper parking lot, bring the children to the lower parking lot, and accompany them as they trick or treat.  In the lower parking lot, about 20 parishioners with their vehicles will have their trunks open and decorated for Halloween; and they will distribute to the children wrapped candy and other treats in plastic bags.  Also, Halloween-themed music will be playing in the lower parking lot.

Strict social distancing is required.  Everyone must wear a face covering; and people from different households must stay at least six feet apart.  (There will be markings on the ground to facilitate this.)  In addition, those distributing the treats will wear disposable gloves.

Parents should screen the candy and other treats before the children eat them (e.g., to ensure that the children are not allergic to the ingredients, such as peanuts or other nuts).  In addition, before the children eat the candy and other treats, the wrapper should be sanitized; and the person opening and eating the candy or treat should sanitize his or her hands.

Welcome St. Denis’s New Associate Pastor
Fr. Raja Yeruva


I am Fr. Raja Shekar Yeruva from the diocese of Guntur, Andhra Pradesh state, India. Although my immediate family is fairly small (one sister and two parents), my extended family is quite large. 

From childhood onward, God gave me the desire to serve as a priest.  I entered the minor seminary at age 12, continued in the major seminary, and was ordained at age 26.  I have been a priest for 16 years.  For the first eight years, I worked in India in different parishes as an associate priest and then as a parish priest (i.e., pastor).

In 2012, I was invited by the Bishop of Gallup, New Mexico, to serve as an associate pastor at Sacred Heart Cathedral in Gallup.  Afterward, I served as a parish administrator at two different parishes in the Diocese of Gallup.  During that time, I also served as a dean, a member of the Presbyteral Council, and a member of the Bishop’s Council.

I came to the Archdiocese of Los Angeles in February 2020 for a different experience.  My first assignment was as an associate pastor at Holy Family (in Glendale), where I served for about seven months.  I have now been assigned to St. Denis to replace Fr. Vincent, who faithfully served here for five years.  (By the way, Fr. Vincent is from the neighboring Khammam diocese, India.)

I look forward to serving here at St. Denis with Fr. John and Fr. Dennis, and getting to know all of you.

Please pray for me, as I make this transition to a new parish.  May God bless and protect all of you and our beautiful parish.

Sincerely yours in Christ,

Fr. Raja

St. Denis Now

St. Denis Now is a video series in which Fr. John Palmer talks with different members of the St. Denis community about what’s happening at St. Denis.  All of the episodes are available on St. Denis’s YouTube channel and Facebook page.

Episode 5:  Bishop David O'Connell teaches us how to pray and speak with Jesus personally from our heart.  He calls this "The Prayer of the Heart."  This simple way of praying changed his life as a priest, and has changed the lives of many others who have learned to pray in this way.

Episode 6:  Fr. Raja Yeruva, St. Denis's new Associate Pastor, introduces himself.  




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.



Important notice

The 42nd Oberammergau Passion Play will be postponed due to the current situation caused by the corona pandemic. The basis for this is a decision of the district administration of Garmisch-Partenkirchen, which prohibits the performance of the event planned from 16.05.2020 to 04.10.2020. The health of our guests and participants is our highest priority, therefore the responsible persons have decided to postpone the premiere of the Passion Play, which was planned for 16 May 2020, until 2022. The premiere is now scheduled for May 21, 2022.

The health of the population is a top priority for the community of Oberammergau and the directing team around Christian Stückl as well. The Corona pandemic has made it impossible to complete this year's play without endangering the performers and guests. Furthermore, the perspective for this year is unclear. A postponement of only a few months seemed unacceptable to everyone involved.
