Welcome to Saint Irenaeus!

We're so happy you're here. We'd like to thank you for checking out our church which has been part of the Cypress community since 1961 - a time when there were more cows than Catholics! We’re an active Catholic community striving daily to strengthen our relationship with God, embrace His message, and answer His call to serve and love one another.  If you've been looking for a way to nurture your faith, reconnect, get more involved, or simply for a place to pray, we welcome you with open arms!


Saturday Vigil: 5 p.m.

Sunday Morning: 6:30 a.m., 8 a.m., 9:45 a.m.*, 11:30 a.m.

Sunday Afternoon: 1:15 p.m.* (Español), 4 p.m.

Sunday Evening: 5:30 p.m.

*9:45 a.m. and 1:15 p.m. Sunday Masses, as well as 8:30 a.m. Monday–Saturday Masses, are also live-streamed on Saint Irenaeus Facebook @stirenaeuschurch.

Want to attend a Mass service, but have never gone to one before and not sure you want to go alone? Our Adult Faith Formation (AFF) is there for you! Send an email or call our Parish Office and we'll arrange for someone from AFF to accompany you. Maybe you're interested in learning more about the Catholic Church. If so, simply send an email to Cassandra at aff-email@sticypress.org. God bless you!

Meet our priests!
