The Apostle Paul encouraged the Colossians "Let the message of Christ dwell among you richly as you teach and admonish one another with all wisdom through psalms, hymns, and songs from the Spirit, singing to God with gratitude in your hearts (Colossians 3:16)."
As believers, Christ is at the center of everything we do. This is especially true when believers gather together for worship. Without Christ, we would have no reason to gather for worship. We would be separated from God and each other. We would cower in shame in the presence of God. But Christ, our Savior, has restored our relationship with God by living perfectly in our place, dying on the cross to pay for all of our sins and rising again to prove that faith is not in vain but continues into the hallowed halls of heaven. As people saved by God, we respond in thanksgiving.
This cycle of receiving from God and giving to God characterizes each of our lives. It also characterizes the way we worship when we gather together. To accomplish this, we use a form of worship that traces its roots to the apostles themselves. It’s called liturgical worship.
Christ is at the center of liturgical worship. Some parts of the liturgy stay the same each Sunday. This is to make sure that Christ is proclaimed and praised during every service. Some parts of the liturgy change every week. These changes are based on the appointed calendar of the church. This calendar makes sure that we cover the important events and teachings of Christ every year.
