Guest Speaker - Mike Scioscia 

Mike Scioscia made his Major League debut with the Los Angeles Dodgers in 1980 with his last MLB appearance in 1992. He was selected for two All Star Games and won two World Series rings during his on-field career.

After his playing career, Mike spent time managing for the Dodgers minor league system before joining the Angel's in 1999. He is the Angel's all-time managerial leader in wins, games managed, division titles, and is the only Angel's manager to date to win a World Series Championship in 2002. While with the Angels', Mike arranged to have mass celebrated in Angel Stadium on Sunday game days, which was open to all players on both sides...yes, even the Yankee and Boston players!

Your Help Needed to Oppose Limits to Sacrament of Confession



Dear Friends,

Our Catholic faith is essential to who we are, how we live, and the way in which we raise our families.

Today, our faith is under attack. We need your immediate help to save the Sacrament of Confession!

SB 360, a bill in the CA Senate, seeks to increase protections of children from abuse and neglect. We agree that keeping children safe is vitally important.

However, this bill claims it must change our sacrament to do so! This is a violation of our First Amendment right to practice our religion free from government interference.

Since 2002, the Archdiocese of Los Angeles has trained over 300,000 lay leaders in abuse prevention and reporting. There are mandated reporters present at every parish, school and hospital. We have updated buildings and policies to put the protection of children first.

We do not need to change the Sacrament of Confession in order to advance our shared goal of fighting child sexual abuse in our society.

In the Sacrament of Confession, we receive absolution for sins and the grace of God to sin no more. Confession strengthens our relationship with Jesus and provides therapeutic benefits to the community as people seek to live better lives.

SB 360 seeks to remove the privacy right to confession for priests and the thousands of lay people who work for the Catholic Church in California. We need your help to tell legislators that they cannot change the way we practice our faith!


1.  Send an email to your CA Senator to be sure he or she understands that we can protect children while also protecting our faith!

2. Call your CA Senator today to tell him or her that you OPPOSE SB 360.
    The legislature cannot change our sacraments!

"Confession is sacred — to every priest and every Catholic." - Archbishop José H. Gomez

An Easter Message from Fr. John

Jesus Christ is risen today!  Alleluia!

Today we celebrate the resurrection of our Lord Jesus Christ, who has changed the course of human history.  Through his suffering, death, and resurrection, he has freed us from sin and eternal death, and has won for us new life.

And this new life doesn’t happen only after we die and enter heaven.  Our new life actually begins with our baptism, which unites us with Jesus.  Through baptism, we begin to die to our former selves; and we put on Christ, who is the resurrection and the life.

During our earthly lives, we need to embrace fully this new life that Jesus has won for us.  And we do this by living the way that he did—by living loving, generous, self-sacrificial lives for God and for other people.  Rather than living for ourselves alone, we live to glorify God and to help others, especially the poor, the needy, and those on the margins of society. 

And Jesus is with us every step of the way to help us to embrace this new life that he has won for us.  In particular, we encounter Jesus in four major ways every week and even every day.  First, we encounter him in Sacred Scripture, which is why we need to read the Bible regularly, and not just on Sundays. Second, we encounter Jesus through prayer, which is why we need to pray every day, and preferably several times a day.  Third, we encounter Jesus in the Sacraments, which is why we need to receive Holy Communion and go to Confession frequently.  Fourth, we encounter Jesus in other people and in our faith community, because, as Jesus says in Matthew 18:20, “Where two or three are gathered together in my name, there am I in the midst of them.” 

Furthermore, we encounter Jesus in all four of these ways at every Mass, which is why going to Mass every Sunday is so important.  At every Mass, we encounter Jesus in Sacred Scripture, in prayer, in Holy Communion, and in the faith community.  If you don’t already attend Mass every Sunday, please start doing so.  This is a good first step to developing a close, personal relationship with Jesus Christ.

But attending Mass every Sunday (or even every day) is not enough.  To develop a deeper relationship with Jesus, we need to read the Bible every day. That’s why I strongly recommend reading the daily Mass readings each day. Reading the Bible in this way is easy because it takes only about five minutes per day.  Furthermore, the daily readings are readily accessible on the U.S. Bishops’ website (, where you can sign up to have them E-mailed to you every morning.  They also are available on smartphone apps such as iBreviary and Laudate.  And if you read the daily readings every day for three years, you will read about 90% of the Gospels, about 70% of the New Testament, and about 20% of the Old Testament. 

We also need the help of a strong faith community to develop a deeper relationship with Jesus.  We are blessed because St. Denis is a very friendly and active parish, and offers a range of activities and something for just about everyone, including children, teens, young adults, middle-aged adults, and seniors.  Please check out this website and our bulletin (especially the cover and page 2), which is available on our website, for an overview of everything that is happening at St. Denis.

For example, please note that we have a good Bible Study Group, which is studying Luke’s Gospel.  They meet every Wednesday in Potthoff Hall from 7:30-9:00 p.m., starting with a light supper at 7:00 p.m.  This Wednesday, they will study and discuss Luke chapter 9.  

We have several devotional prayer groups, which are listed on the cover the bulletin, including a Christian Meditation Group, which meets every Wednesday at 7:10 p.m. in the church’s “crying room” that is closest to the statue of the Blessed Virgin Mary.  This Meditation Group will teach you the ancient Christian practice of silent meditation. 

In addition, we have a very active Knights of Columbus and Women’s Council, which are service-oriented fellowship groups.  We have an active Cursillo Group, which has an upcoming retreat for men from April 25-28 and a retreat for women from May 2-5.  And on Sunday, April 28, we will start a new cycle of GriefShare to help those who are mourning the death of a loved one.

Finally, if you are just starting to get involved in the parish, I recommend joining Alpha, which meets in Potthoff Hall every Saturday morning from 9:00-10:30 a.m. (beginning with a free continental breakfast at 8:30 a.m.).  Alpha participants explore the Christian faith by eating a meal, watching a thought-provoking video, and discussing a different faith-related question each week.  All are welcome, including active and inactive Catholics, non-Catholics, agnostics, and atheists.

Jesus Christ is risen today!  May you and your family have a very blessed and joyful Easter.

Archbishop José Gomez is inviting all Catholics to make their annual commitment to the 2019 Together in Mission Appeal. All of the money raised through Together in Mission is used to assist poor parishes and schools in the Los Angeles Archdiocese that cannot survive without outside financial support. For example, last year 62 local parishes and 40 local parochial schools received necessary funding that allowed them to continue to do the Lord’s work.

This year, our parish has been asked to raise $135,800. By contrast, in 2018, 325 donors helped to raise $121,472, which means that we were one of the most generous parishes in the Archdiocese. We can meet this year's higher goal if every family in our parish pledges to Together in Mission.

This year’s theme of “Our Story is Hope” 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 by using the materials that were recently mailed to your home; by filling out a pledge card that is available in the pews and in our Pastoral Office; or by going online at When making a pledge, please indicate that St. Denis is your parish so that your pledge and donations will count toward St. Denis 2019 goal of $135,800

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.
