Catholic Organizations & Movements to Join

From historic fraternal orders to modern lay movements, Catholic organizations are where the faith comes alive in community. Discover the right apostolate for you — then find a local chapter and connect with members near you.

The richness of Catholic lay organizations

For two thousand years, Catholics have gathered into organizations, apostolates and movements to live the faith more fully together than they ever could alone. These Catholic groups carry distinct charisms — gifts of the Holy Spirit expressed through a particular way of praying, serving and evangelizing. Some are ancient; many of today's most vibrant Catholic lay organizations were born in the last century as the Church called every baptized person, not only priests and religious, to share in her mission.

A fraternal order like the Knights of Columbus channels charity and brotherhood among Catholic men. An apostolate like the Legion of Mary sends laypeople out to visit the lonely and pray with the sick. Renewal movements such as Cursillo and Regnum Christi form disciples through retreats and small groups, while the Secular Franciscans weave the spirit of St. Francis into ordinary family and working life. Together these Catholic movements show that holiness is meant to be lived in community, in the world.

Our app maps the Catholics, groups and events around you, so you can move from curiosity to a real local chapter and real friendships.

Frequently asked questions

What are Catholic lay organizations and movements?

Catholic organizations and movements are communities — many led by laypeople — that gather Catholics around a shared spirituality, charism or mission. They include fraternal orders like the Knights of Columbus, apostolates like the Legion of Mary, and renewal movements like Cursillo and Regnum Christi. Each offers prayer, formation, fellowship and concrete service to the Church.

How do I join a Catholic organization?

Catholic Connect helps you find members and chapters near you so that first step is easy.
