Difference Between Nun and Sister

Key Differences

A nun is a woman who belongs to a religious order, often living in a convent, and who has usually taken solemn vows of poverty, chastity, and obedience. The term "nun" usually implies a more cloistered, contemplative life focused on prayer and spiritual growth. A sister, on the other hand, is also a woman belonging to a religious community, but she usually takes what are known as "simple vows" and might not live in a convent.
Both nuns and sisters are committed to a religious life, but their roles and responsibilities can differ significantly. Nuns often spend more time in prayer and contemplation, devoting their lives to spiritual matters within the confines of a monastery or convent. Sisters are generally more active in community service, such as education, healthcare, or social work, while still maintaining a strong prayer life.
While both nuns and sisters are religious figures within the Christian faith, primarily in the Catholic, Anglican, and Eastern Orthodox traditions, their public visibility often differs. Nuns, due to their more contemplative lifestyle, may not be as publicly visible as sisters, who are often involved in community outreach and service projects.
The terms "nun" and "sister" are sometimes used interchangeably, but doing so overlooks the nuanced differences between the two. The primary distinction lies in the nature and complexity of their vows, the lifestyle they lead, and the degree to which they engage with the broader community.
