A confraternity is an officially established association of the Catholic Church, organized around some spiritual or evangelistic work. It may be comprised of lay men and women, religious, or clerics — or any combination of these. Historically there have been a variety of kinds of such associations — older terms used were “pious unions” or “sodalities.” The Code of Canon Law (1983) draws all such associations under one umbrella, where members “strive in a common endeavor to foster a more perfect life, to promote public worship or Christian doctrine, or to exercise other works…such as initiatives of evangelization, works of piety or charity, and those which animate the temporal order with a Christian spirit” (CIC 298).
Though its roots go back to the late middle ages, the Angelic Warfare Confraternity was officially established by Pope Benedict XIII in 1727, and put under the direction of the Master General of the Order of Preachers. Its members dedicate themselves to living and promoting the virtue of chastity in the world. To become a member, one must be enrolled in an official register kept by the Order. Such registers are generally connected with Dominican houses, or houses which keep a register for a given region.
