Isaiah 53:5: But he was wounded for our transgressions, he was bruised for our iniquities; upon him was the chastisement that made us whole, and with his stripes we are healed.
Dies Domini - Parts 61 & 62 - Pope John Paul II (Apostolic Letter on the Lords Day)
61. As the seventh day blessed and consecrated by God, the "shabbat" concludes the whole work of creation, and is therefore immediately linked to the work of the sixth day when God made man "in his image and likeness" (cf. Gn 1:26). This very close connection between the "day of God" and the "day of man" did not escape the Fathers in their meditation on the biblical creation story. Saint Ambrose says in this regard: "Thanks, then, to the Lord our God who accomplished a work in which he might find rest. He made the heavens, but I do not read that he found rest there; he made the stars, the moon, the sun, and neither do I read that he found rest in them. I read instead that he made man and that then he rested, finding in man one to whom he could offer the forgiveness of sins". (106) Thus there will be for ever a direct link between the "day of God" and the "day of man". When the divine commandment declares: "Remember the Sabbath day in order to keep it holy" (Ex 20:8), the rest decreed in order to honour the day dedicated to God is not at all a burden imposed upon man, but rather an aid to help him to recognize his life-giving and liberating dependence upon the Creator, and at the same time his calling to cooperate in the Creator's work and to receive his grace. In honouring God's "rest", man fully discovers himself, and thus the Lord's Day bears the profound imprint of God's blessing (cf. Gn 2:3), by virtue of which, we might say, it is endowed in a way similar to the animals and to man himself, with a kind of "fruitfulness" (cf. Gn 1:22, 28). This "fruitfulness" is apparent above all in filling and, in a certain sense, "multiplying" time itself, deepening in men and women the joy of living and the desire to foster and communicate life.
62. 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 ass, 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.
