Cursillos in Christianity is a Movement which, by its own Method, attempts from within the Church, to give life to the essential Christian truths in the singularity, originality and creativity of the person. In discovering their potential and accepting their limitations, they will direct their freedom with their conviction, reinforce their will with decisiveness and direct their friendship with the virtue of constancy in their day-to-day life, personally and with others.
