Communal prayer is very important for Catholics. They participate in communal prayer every Sunday when they celebrate the Eucharist at their church. The Eucharist is the central act of worship where Catholics remember Jesus' words and actions at the Last Supper. As a community of faith, Catholics gather together on Sundays and important times in the liturgical year like Christmas and Easter to pray, worship, and respond to the mystery of their faith. The layout of the church helps facilitate communal prayer, and coming together at the Easter Triduum is significant as Catholics participate in worship over this sacred time.
