What does the term 'Brother' mean in the Roman Catholic faith?

In the Roman Catholic faith, the term 'Brother' specifically refers to a member of a religious order who has not received ordination as a priest. Brothers typically live in community and dedicate their lives to serving God and others, often through various forms of ministry, education, or charity. They take vows, similar to priests, but do not perform sacraments or serve in the liturgy in the same way that ordained clergy do.

This distinction is crucial in understanding the roles within the Church. While a man ordained as a priest performs the sacramental functions and acts in a clergy capacity, a Brother focuses on living out his vocation through service and community living without the priestly orders. This makes 'Brother' an important designation within the religious order context, separate from ordained roles like priests or deacons.
