About Us

… “Centered in God, for whom alone we go forward or stay back.”—Catherine McAuley

We Sisters of Mercy are an international community of Roman Catholic women who dedicate our lives to the Gospel of Jesus and take vows of poverty, chastity, obedience and service. Inspired by the life of Jesus and by our founder Catherine McAuley, we envision a just world for people who are poor, sick and uneducated. We commit our lives to God and our resources to serve, advocate and pray for those in need around the world.

In addition to the three vows (poverty, chastity and obedience) all Catholic sisters take, as Sisters of Mercy, we also take a fourth vow of service.

Today, more than 2,900 Sisters of Mercy of the Americas make a difference in the lives of others in North, South and Central America, the Caribbean, Guam and the Philippines.
