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 - Keeping the Lords Day Holy - Parts 65 & 66 - Pope John Paul II
65. By contrast, the link between the Lord's Day and the day of rest in civil society has a meaning and importance which go beyond the distinctly Christian point of view. The alternation between work and rest, built into human nature, is willed by God himself, as appears in the creation story in the Book of Genesis (cf. 2:2-3; Ex 20:8-11): rest is something "sacred", because it is man's way of withdrawing from the sometimes excessively demanding cycle of earthly tasks in order to renew his awareness that everything is the work of God. There is a risk that the prodigious power over creation which God gives to man can lead him to forget that God is the Creator upon whom everything depends. It is all the more urgent to recognize this dependence in our own time, when science and technology have so incredibly increased the power which man exercises through his work.
66. Finally, it should not be forgotten that even in our own day work is very oppressive for many people, either because of miserable working conditions and long hours — especially in the poorer regions of the world — or because of the persistence in economically more developed societies of too many cases of injustice and exploitation of man by man. When, through the centuries, she has made laws concerning Sunday rest, (109) the Church has had in mind above all the work of servants and workers, certainly not because this work was any less worthy when compared to the spiritual requirements of Sunday observance, but rather because it needed greater regulation to lighten its burden and thus enable everyone to keep the Lord's Day holy. In this matter, my predecessor Pope Leo XIII in his Encyclical Rerum Novarum spoke of Sunday rest as a worker's right which the State must guarantee. (110)
