What is Cursillo

Cursillo is a movement of the church which trains and supports its members to live out their apostolic mission. Christians are introduced to Cursillo through a three day weekend. They are supported by small groups and these small groups also meet together in larger groups.

...But grace was given to each of us according to the measure of Christ's gift. And His gifts were that some should be apostles, some prophets, some evangelists, some pastors and teachers, to equip the saints for the work of ministry, for building up the body of Christ...

Ephesians 4:7, 11-12
