Saint Irenaeus Catholic Church has been part of the Cypress community since 1961 - a time when there were more cows than Catholics! Since then we have grown into a vibrant, active parish with as many ministries as diverse as we are... from bible study to pew angels, feeding the hungry to Health Ministry, Fall Fiesta to a variety of music ministries serving our children, teens, adults, Spanish speaking parishioners, and the Filipino Catholic Federation. If you're looking for an opportunity to participate, you'll find it at Saint Irenaeus Catholic Church.

Been looking for a way to nurture your faith, reconnect, get more involved, or simply a place to pray? We welcome you with open arms!

May the Lord in his goodness lead us all closer to him.

And by our love and service to one another, may we hear him say to us,

"Well done, my good and faithful servant... Come, share your master's joy" (Mt 25:23).

World Day of the Sick Mass

Saturday, February 8 at 8:30 a.m.

In solidarity with all the infirm and their caregivers, Saint Irenaeus Church is having a World Day of the Sick Mass with the celebration of the Sacrament of Anointing of the Sick within Mass. Those who are in need of healing and anointing are encouraged to attend.

February 11 is World Day of the Sick, an observation started by Pope St. John Paul II as a way for believers to offer prayers for those suffering from illnesses. The day coincides with the commemoration of Our Lady of Lourdes. People around the world take the time to pray for the sick and for those who work hard to alleviate the sufferings of the sick on this day. This year we are observing the day a few days early on February 8.
