It is certainly news to me that we Christians no longer hold to, The Ten Words as noted in the Decalogue, Deuteronomy in which the Sabbath Law is the 3rd commandment.
It is the duty of Christians therefore to remember that, although the practices of the Jewish Sabbath are gone, surpassed as they are by the "fulfilment" which Sunday brings, the underlying reasons for keeping "the Lord's Day" holy — inscribed solemnly in the Ten Commandments — remain valid, though they need to be reinterpreted in the light of the theology and spirituality of Sunday: "Remember the Sabbath day to keep it holy, as the Lord your God commanded you. Six days you shall labour, and do all your work; but the seventh day is a Sabbath to the Lord your God. Then you shall do no work, you, or your son, or your daughter, or your servant, or your maid, or your ox, or your ***, or any of your beasts, or the foreigner within your gates, that your servant and maid may rest as well as you. You shall remember that you were a servant in the land of Egypt, and the Lord your God brought you out from there with a mighty hand and an outstretched arm. Therefore the Lord your God commanded that you keep the Sabbath day" (Dt 5:12-15). Here the Sabbath observance is closely linked with the liberation which God accomplished for his people.
Christ came to accomplish a new "exodus", to restore freedom to the oppressed. He performed many healings on the Sabbath (cf. Mt 12:9-14 and parallels), certainly not to violate the Lord's Day, but to reveal its full meaning: "The Sabbath was made for man, not man for the Sabbath" (Mk 2:27). Opposing the excessively legalistic interpretation of some of his contemporaries, and developing the true meaning of the biblical Sabbath, Jesus, as "Lord of the Sabbath" (Mk 2:28), restores to the Sabbath observance its liberating character, carefully safeguarding the rights of God and the rights of man. This is why Christians, called as they are to proclaim the liberation won by the blood of Christ, felt that they had the authority to transfer the meaning of the Sabbath to the day of the Resurrection. The Passover of Christ has in fact liberated man from a slavery more radical than any weighing upon an oppressed people — the slavery of sin, which alienates man from God, and alienates man from himself and from others, constantly sowing within history the seeds of evil and violence.
The main point of the precept is not just any kind of interruption of work, but the celebration of the marvels which God has wrought.
The joy with which God, on humanity's first Sabbath, contemplates all that was created from nothing, is now expressed in the joy with which Christ, on Easter Sunday, appeared to his disciples, bringing the gift of peace and the gift of the Spirit (cf. Jn 20:19-23). It was in the Paschal Mystery that humanity, and with it the whole creation, "groaning in birth-pangs until now" (Rom 8:22), came to know its new "exodus" into the freedom of God's children who can cry out with Christ, "Abba, Father!" (Rom 8:15; Gal 4:6).
