St. Irene Catholic Church

About this church

St. Irene Catholic Church celebrates weekend Mass Saturday at 4:30 p.m. and Sunday at 8 and 10 a.m. The Saturday vigil and 10 a.m. Sunday Mass are also livestreamed on YouTube and Facebook. Weekday liturgies are Monday and Tuesday at 8 a.m., Wednesday at noon, and Thursday and Friday at 7 a.m. Reconciliation begins Saturdays at 3:30 p.m. Thursday Eucharistic Adoration follows the 7 a.m. Mass and continues until noon; on the first Friday, a Rosary at 6:30 p.m. precedes Holy Hour at 7. The church sits at the southeast corner of Warrenville Road and Warren Avenue, reached from I-88 via Winfield Road.

Faith formation spans religious education, sacramental preparation, youth ministry, adult learning, and Children's Liturgy of the Word during the 10 a.m. Mass on the second and fourth Sundays. Worship ministries include altar servers, lectors, extraordinary ministers of Communion, musicians, ushers, greeters, and liturgy planners. Service and social groups support a neighborhood food pantry, Bridge Communities, adults over 55, parish hospitality, women, the Knights of Columbus, prayer shawls, and flexible volunteer projects. The parish traces its roots to a mission whose first official Mass was held in the Warrenville School House and later operated a school for nearly 70 years. Published pages do not give Mass length, parking layout, step-free entrance guidance, hearing assistance, child care during liturgy, or Communion guidance for non-Catholic visitors.
