Our welcoming Christian community of St. Irenaeus Parish inspired by the words of our patron - "Humankind fully alive is God truly glorified" - journeys together to bring the love of Christ to all in our parish family through worship, faith formation, social justice, and loving service while reaching out to the broader community.
