Sunday Service is a religious service held on Sundays in many Christian denominations. It typically includes a MASS, which is a celebration of the Eucharist, and a LITURGY, which is a set of prayers and readings from the Bible. The MASS and LITURGY are usually accompanied by music and other forms of worship. Sunday Service is an important part of the Christian faith and is a time for believers to come together to celebrate their faith and to be reminded of God's love.
