Liturgy November 7
Every week, on the day which she has called the Lord's day, (the Church) keeps the memory of the Lord's resurrection (Vatican Council II, SC 102).
At the time of the Apostles, the community accepted as its Sabbath the day of Jesus' Resurrection, that is, the "first day" of the week. In effect, this choice was a significant change in the biblical tradition up to that time. The early Church took seriously the requirement of biblical Sabbath, but she began to observe the eighth day of the week rather than the traditional seventh day. There is no evidence in the New Testament authorizing the change, neither on the part of Jesus, nor on the part of the Apostles. It is an accomplished fact in the practice of the post-Apostolic Church, the legacy, no doubt, of a decision of the Apostles. The Jewish Sabbath was observed in connection with the end of the divine act of creation. In light of the facts that the Resurrection took place on the first day of the week, that the Risen Christ preferred this day to manifest himself to the disciples and that Pentecost was observed on the first day, Christians made the decision to transform Sunday into the day of Sabbath. Christian Sabbath retained the character of rest and prayer, but now it commemorated the New Creation in Christ. Sunday became the most significant day for the “anamnesis,” the memorial, of the Death and Resurrection of Jesus.
