Saint Irenaeus Church

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, feeding the hungry, Evangelization Retreat, 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.
