Cursillo (pronounced KER-see-oh) is an abbreviation of the full title: Cursillo de Cristiandad which means "A Short Course in Christian Community Living."
The weekend is a three-day learning, sharing, inspirational experience of living in a Christian community. During the three days of a Cursillo weekend a person not only hears inspiring talks on what it really means to be a Christian, but actually experiences the joy of building and being part of a genuine Christian community.
