Pastor's Corner

 Dear Sisters and Brothers,

Happy Easter! I hope that the you're reaping the fruits of this Season which is peace, Joy and Love.

If you're logging into our parish website for the first time, know that you're most welcome. We're happy to invite you to join us for the weekend experience (Saturday/Sunday) in our Parish where "faith inspires life, and life inspires faith.”

Much has happened in our Parish Community during Lent, Easter Sunday and the Sunday after Easter. We've had the privilege of witnessing many initiations through the sacraments of Baptism, Confirmation and First Eucharist. It's truly a sign of God's blessing of Our Parish Community's faithfulness to the gospel way of life. Congratulations and blessings!

Our own Bishop Michael Barber was here last Sunday and anointed 33 young women and men. This weekend, we will witness the reception of First Eucharist by children.

I invite you to be welcoming to the families and extended families of these children who’ve journeyed with them this journey of faith. Some of them may be coming to church for the first time in a long time; let's welcome them with open arms. There may be some young families with little children; others, with children with special needs. Let's be a family to them and appreciate what these families go through day after day for them.

If there's some way in which our Parish Church or I could be if assistance to you, do reach out to me and we'll do all we can to address the need. My email is This email address is being protected from spambots. You need JavaScript enabled to view it. and my phone number is 925-939-7911, ext.105.

With Easter blessings and prayers,

Fr. William Rosario, Pastor


ALPHA - Wednesdays 7pm in Vista


Date: Wednesdays 7:00 pm
Location: Mullen Commons Vista


Last Fall we launched the first-ever Alpha Course at St. John Vianney and it was a success! 75 parishioners gathered to explore some of life's big questions; questions that we rarely have enough time to think about such as: Why am I here? What's my purpose? Where am I heading? Is there more to life than this? Many made new friends and some of those ‘new’ friends continue to meet in each other’s homes to share faith and hospitality.


If you crave a deeper connection with God and others, try Alpha. Alpha is a rare opportunity to explore questions of life and the Christian faith in a friendly, open and informal environment. No pressure. No charge. No follow up.


Alpha runs in churches, homes, coffee shops, and bars all over the world. It typically includes a meal, a video and time afterwards for sharing your thoughts. Alpha is open to all people, whether you’re a regular parishioner who’s just curious about what this new program might be or you’re interested in learning more about Christianity, you are welcome to attend!

Moms Ministry Spring Series 

Join us as we explore The Seven Levels of Intimacy: The Art of Loving and the Joy of Being Loved, by Matthew Kelly.  Intimacy is a throwaway buzzword in pop psychology, yet it remains a litmus test for the health of relationships and is something everyone should strive for.  Intimacy is the one thing a person cannot live happily without.  What is intimacy? Who energizes you? Why do they energize you? How do you want to be remembered?

Lower Mullen Commons, Room 3, Wednesdays, April 25, May 9 and May 23 at 9:30-11am.  RSVP for Spring Series

We will have a few copies of the book available for purchase.  You can also order your book at amazon.com or DynamicCatholic.com.

SJV Moms Ministry’s aim is to bring together moms of ALL ages and stages for faith formation, fellowship, support, friendship and spiritual growth as we journey through the biggest Ministry entrusted to us. For more information, email us: This email address is being protected from spambots.
