The lives of monks and nuns in Catholic religious congregations or orders are a form of Consecrated Life, expressed through their voluntary commitment to follow Christ completely, in the particular spirituality and charismatical tradition of the religious order they have chosen.
Catholic monks and nuns, upon taking their religious vows, often add the abbreviation of religious order after their name (e.g., Sr.Helen Alford, OP or Fr. Jacques Philippe, CB...). The abbreviations of Roman congregations usually derive from Latin, English, French, or other languages. The following list provides the meanings of the abbreviations for various religious orders.
