Society of St. Vincent de Paul
Men and women meet in local groups called conferences to help neighbors facing hardship. Members visit people in their homes, listen to their needs, and may help with food, housing, or utility bills. The international society’s website can help you find its work in your country.
Legion of Mary
Catholic men and women pray together and serve their parish under the patronage of Mary. Active members meet weekly and undertake work such as visiting the sick. Auxiliary members support them through daily prayer, including the Rosary.
Secular Franciscan Order
Single and married Catholics follow the example of St. Francis of Assisi in their family life, work, and community. Members gather in local fraternities for prayer and formation. Those who discern this vocation can make a lifelong profession to live according to the Franciscan rule.
Lay Dominicans
Confirmed Catholic men and women in full communion with the Church can explore a vocation in the Dominican family. Members gather in fraternities for prayer and study, then share what they have learned through teaching, conversation, and the witness of daily life.
Knights of Columbus
Practicing Catholic men age 18 and older can join this fraternal organization. Through local councils, Knights support families, serve their parishes, and organize charitable projects in their communities.
Catholic Daughters of the Americas
Catholic women gather in local chapters called courts for friendship, prayer, and charitable service. Members work together on community projects and take on leadership roles. The membership page explains how to find a court or ask about joining.
World Union of Catholic Women’s Organisations
This international network brings Catholic women’s organizations together across countries. Membership is for organizations. Individual women can use its directory, arranged by region and country, to find a member group and contact it about joining.
