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).
