Immaculate Conception

About this church

Immaculate Conception Church is an Irwin parish of the Catholic Diocese of Greensburg, established in 1868. Parish life centers on Mass, the sacraments, faith formation, prayer, and service to neighbors. Current outreach includes a monthly community meal with other Irwin churches, support and bereavement ministries, and programs for children and youth, giving the congregation a public role beyond its regular liturgical schedule.

The Saturday vigil Mass begins at 4:30 p.m.; Sunday Masses are at 8:00, 10:00, and 11:30 a.m. Weekday Mass is Monday through Friday at 7:45 a.m. Saturday morning Mass is ordinarily at 8:00, except on the first Saturday of the month, when a First Saturday Anointing Mass is held at St. Elizabeth Ann Seton at 8:30 instead. Confession is offered Saturday from 8:30 to 9:30 a.m., also excluding the first Saturday. The Divine Mercy Chaplet is prayed Monday through Friday at 3:00 p.m. These first-Saturday exceptions matter for visitors because the alternate Mass is at another parish location. Holy-day schedules and funerals are maintained on separate official pages and may replace normal routines. The parish homepage and Facebook feed carry the most current event notices.
