What is a sister or nun?
A sister or nun is a woman who belongs to a religious order, or community. Many people use the word nun interchangeably with sister, but technically nuns are those who live a cloistered (or enclosed) monastic life; whereas sisters serve in an active ministry. After a period of preparation (called formation) sisters and nuns take lifelong vows. Usually they take vows of poverty, chastity, and obedience; that is, they promise to live simply, to live celibately, and to follow the will of God through their community.
