We are a welcoming and reconciling openness to all people, celebrating the diversity of our urban neighborhood; We are witnessing to a contemporary understanding and practice of the Churchs teaching, in the light of the Second Vatican Council; We are living out our call to discipleship by offering sacramental life, service, teaching, and healing to all Gods people, which will, at times, involve a cost to ourselves; We are nurturing in our lives a deeper spiritual relationship with the Lord.
