1592 Enumerated Festivals by Hospinian
I. The observance of the Sabbath is a part of the moral law; for the decalogue wherein the Sabbath is commanded is the most essential part of the moral law. Inasmuch as the other precepts of the decalogue pertain to us (for the law is written for one and all, as a rule of morality) so like- wise does the observance of the Sabbath, being a moral duty, belong to it.
2. Only the ceremonies instituted by Moses have been abrogated; the Sabbath, however, is not of Moses. It has been kept holy since the beginning of the world, and therefore has not been abrogated.
3. The benefit of creation is intended for all men, Christians as well as Jews; and, consequently, belongs to all ages in which men have existed; but therefore, the symbol that is to keep the remembrance of creation fresh among men, must also be observed by all. Paster, Pentecost, and the feast of tabernacles are based on a different foundation; for they are holidays on which are to be commemorated the benefits God had shown especially to the children of Israel. But the Sabbath does not concern the Israelites alone.
4. The Sabbath is, according to Ex. 31:17, in the covenant made by God, called the eternal, i. e., the everlasting covenant.
5. The spiritual sabbath rest is the same in the Old as in the New Testament; therefore the Sabbath ought to be the same also."
