No! Tres Dias is not a substitute for church. Participation in Tres Dias cannot replace active, contributing membership in your church. Tres Dias can only help awaken the need for Christ in your life, or strengthen the walk you already have with Him. This awakening and strengthening takes on its fullest meaning when you strive to play a more committed and active role in your church community. Participants are expected, with the help of the Holy Spirit, to work toward transforming environments with the gospel of Christ
