Catholic nuns are women who dedicate their lives to serving God and the Church through a religious community. They typically take vows of poverty, chastity, and obedience, committing themselves to a life of prayer, service, and community living. Nuns often engage in various ministries, such as education, healthcare, and social work, helping those in need. Nuns belong to different religious orders, each with its own specific mission and way of life. Some well-known orders include the Sisters of Mercy, the Franciscan Sisters, and the Dominican Sisters. Their contributions have significantly impacted society, particularly in areas like education and healthcare.
