A religious priest or brother belongs to a particular religious order, such as the Franciscans, Jesuits, Benedictines, or Divine Word Missionaries.
Each religious order is founded to fulfill a particular need in the Church through various ministries like teaching, monastic prayer and missionary service.
Priests perform sacramental ministry such as celebrating Mass and administering the sacraments.
A religious brother is a man committed to living the Consecrated Life in response to a call from God. Brothers are engaged in a variety of ministries in keeping with the charism of their congregation and model the person of Jesus through the relational manner in which they serve.
