Tres Dias is unique in that it is an ecumenical Christian experience open to all who desire a deeper relationship with the Lord Jesus. Tres Dias is not sponsored by any one Christian denomination.

The Tres Dias weekend is a three day retreat centered on growth in an individual's Christian life. The dynamics involved, the schedule used, the order of the talks and events, the total content is basically the same as that developed for the first Cursillo weekends held on the Spanish Island of Majorca. It should be the same whether held in Spain, Australia, Korea or the United States. It is designed to meet the needs of all Christians where ever they find themselves in their Christian walk.

The dynamics of each weekend develop slowly to allow each candidate to move comfortably through each experience. On Friday the emphasis is more personal and provides for introspection; Saturday is action oriented, the person of Christ is the focus; and Sunday the direction is toward the community. At the same time the level of witness and personal testimony increases during each day and each day begins at a higher level than the day before. The talks each day begin with the mind or understanding, move to the will or commitment; the final lay talk of each day stressing the heart or love.

All of these elements are a direct out growth of the Cursillo weekend and the urgent desire on the part of a few Pescadores to provide a similar spiritual experience for fellow Protestants. Thus Tres Dias, an ecumenical movement came into being through the energetic and loving support of the Cursillo community.

One great strength of each Tres Dias community is its ecumenism. On each weekend, candidates and team members including the spiritual directors represent various denominations and congregations. In addition, team members and candidates represent a wide range of adult age groups, varying marital situations, and differing professional, educational and cultural backgrounds.

The ecumenical factor in Tres Dias brings to many Christians a new and irreplaceable growing experience. It is a "love feast" that expands one's life in the Christian community to other congregations, clergy, and brothers and sisters in Christ. As a result of this experience it extends outreach for all and strengthens one's resolve to participate in and expand a Christ-centered environment.
