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!

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.


Your Help Needed to Stop Abortion Expansion on College Campuses



SB 24 would create a fund for UCs and CSUs to provide medical abortions in their student health centers. This bill would require all UC and CSU student health centers to use the additional funding to provide students with medical abortions on campus. Last year, the Archdiocese of Los Angeles drew significant opposition to a similar bill SB 320. Although, the bill passed in both houses (Senate and Assembly) it was ultimately vetoed by Governor Jerry Brown. Today we are asking the Catholic community to join in a Statewide novena to oppose SB 24. 


Contact your state legislator to oppose SB24
If the link does not work, please try again in 24 hours; or contact your state legislators (state assembly member and state senator) by other means (such via telephone or letter).

Pray a novena to oppose SB 24
