"But keep the Sabbath, and the Lord's-day festival; because the former is the memorial of the creation, and the latter, of the resurrection. But there is one only Sabbath to be observed by you in the whole year, which is that of our Lord's burial, on which men ought to keep a fast, but not a festival. For inasmuch as the Creator was then under the earth, the sorrow for him is more forcible than the joy for the creation; for the Creator is more honorable by nature and dignity than his own creatures." In book vii., section 2, paragraph 30, he says: "On the day of the resurrection of the Lord, that is, the Lord's day, assemble yourselves together, without fail, giving thanks to God," etc. In paragraph 36, the writer brings in the Sabbath again: "O Lord Almighty, thou hast created the world by Christ, and hast appointed the Sabbath in memory thereof, because that on _that day_ thou hast made us _rest from our works_, for the meditation upon thy laws." In the same paragraph, in speaking of the resurrection of Christ, the writer says:-- "On which account we solemnly assemble to celebrate the feast of the resurrection on the Lord's day," etc. In the same paragraph he speaks again of the Sabbath: "Thou didst give them the law or decalogue, which was pronounced by thy voice and written with thy hand. Thou didst enjoin the observation of the Sabbath, not affording them an occasion of idleness, but an opportunity of piety, for their knowledge of thy power, and the prohibition of evils; having limited them as within an holy circuit for the sake of doctrine, for the rejoicing upon the seventh period." In this paragraph he also states his views of the Sabbath, and of the day which he calls the Lord's day, giving the precedence to the latter:-- "On this account he permitted men every Sabbath to rest, that so no one might be willing to send one word out of his mouth in anger on the day of the Sabbath. For the Sabbath is the ceasing of the creation, the completion of the world, the inquiry after laws, and the grateful praise to God for the blessings he has bestowed upon men. All which the Lord's day excels, and shows the Mediator himself, the Provider, the Law-giver, the Cause of the resurrection, the First-born of the whole creation," etc. And he adds: "So that the Lord's day commands us to offer unto thee, O Lord, thanksgiving for all. For this is the grace afforded by thee, which on account of its greatness has obscured all other blessings."
