Experience this life-changing weekend at the Retreat House in Easton, MA

From their site,

To explain Cursillo to someone who has never experienced Cursillo is at best, difficult. Often, for those who have experienced Cursillo it is still somewhat mystifying. This is not because the Cursillo Movement is a "secret" organization. The reason behind the mystery is God. No one can fully explain how God touches each person in His special / unique way throughout the various elements of the Cursillo Movement.

Cursillo (pronounced kur-see-yo) is a Spanish word meaning a short course. It is an abbreviated form of Cursillo de Cristiandad (short course to prepare Christians). It is not a theoretical course, nor is it a retreat. It is first and foremost an experience. It must be lived. It is a life-changing experience, which brings with it the discovery of the basis of Christianity and its fundamental significance to our lives.

The Cursillo experience begins with a weekend course in basic Christianity. The three-day course gives the participant practical insights into the everyday life of faith and service. The weekend is a back-to-basics experience which often deepens and rounds out what one has learned about Christ earlier in life. The program begins on Thursday evening and concludes on Sunday evening.

The weekend is led by a team of lay volunteers and clergy. They prepare extensively for this three-day course in basic Christianity. As one might expect, there are talks on various religious topics, and each talk is followed by a discussion. Mass is celebrated each day, and there is an opportunity for the sacrament of reconciliation. Morning and evening prayer, as well as a few devotions, are part of the schedule. Meals are hearty, and there are regular breaks in the schedule.

Hundreds of thousands of American Catholics have lived Cursillo, so that a deep pool of people is available to support one another.
