St. Paul Inside the Walls is the Catholic Center for Evangelization for the Roman Catholic Diocese of Paterson.

Located at the campus of the former Bayley-Ellard High School in Madison, New Jersey, the restored brick Colonial Revival style mansion and 1960's era school building house both the unique outreach, community, formation and training programs of St. Paul's and the various ministries and departments of the Office of Evangelization of the Diocese of Paterson.

The Office of Catechesis coordinates, guides, and trains all those in parishes who are involved in forming faith and educating disciples in a systematic and intimate knowledge of the person and message of Jesus Christ, including parish catechists, directors and coordinators of religious education, catechetical leaders, RCIA and adult faith formation coordinators, and family faith formation  coordinators.

Wherever you may be in your faith journey, St Paul’s Young Adults offers opportunities to explore a belief in God in open dialogue, social and service events, and Sunday Mass with others.

The Family Life Office ministers to families, engaged couples, married couples, the separated and divorced, those who are grieving, and others, and coordinates and guides those who minister to these groups at the parish level.
