History of Tres Dias
With a broadening vision of what these small sharing groups (reunion groups) could accomplish, weekly meetings produced periodic retreats where the reality of living a Christian life was intensely taught and experienced through support by reunion groups. These retreats became known as Cursillo de Christiandad, which means “short course in Christianity.”
The Cursillo movement was confined to Spanish speaking countries until the late 1950’s when a group of men from the Spanish Air Force, who were in training in Texas and were in a Reunion Group, conducted the first Cursillo in the United States. Among the Spanish-speaking people, the movement began to spread across the United States. The first English speaking Cursillo was held in the early 1960’s.
Protestants who attended the weekends saw the need to make the experience available to other Protestants. Various denominations developed their own renewal programs modeled after the Roman Catholic Cursillo de Christiandad. For various reasons, a need for an ecumenical protestant three-day renewal experience was felt. This led to the development of the interdenominational Tres Dias.
