The liturgical year takes us through the Scripture’s account of the life of Jesus and the life of His Church, his Body.
The Liturgy and the calendar of fast and feast days draw our lives around the life of Jesus. All reality is centered in Jesus ... who holds all things together by the Word of his power.
The sanctification of time
Genesis 2:1
By the 7th day God had finished the work he had been doing; so on the 7th day he rested from all his work. And God blessed the 7th day and sanctified it (made it holy), because on it he rested from all the work of creating that he had done.
In the coming of Jesus, in his incarnation, life, crucifixion, resurrection, ascension and sending of the Holy Spirit, the curse of sin and death within the cosmos was reversed. In Christ, time no longer is pointed towards death but eternal life. Death reigned in Adam, now life reigns in Christ, the second Adam (Romans 512-21).
The Church in worship through liturgical calendar is a means of redeeming time, blessing time, reclaiming it for its intended purpose before sin and death entered the world. In Christ, time is forever altered and centered in him. The celebration of the Eucharist is the way in which time is sanctified. All reality is rooted in the life, death and resurrection of Jesus Christ, the origin of all the created order. Through him all things were made.
For from him and through him and to him are all things. To him be glory forever. Amen (Rom 11:36).
