The Longer Catechism of the Orthodox, Catholic, Eastern Church · St. Philaret of Moscow

537. Is the Sabbath kept in the Christian Church? It is not kept, strictly speaking, as a holy day; but still in memory of the creation of the world, and in continuation of its original observance, it is distinguished from the other days of the week by a relaxation of the rule for fasting.
Q. 537
538. How, then, does the Christian Church obey the fourth commandment? She still to every six days keeps a seventh, only not the last of the seven days, which is the Sabbath, but the first day in every week, which is the Day of the Resurrection , or lord's Day.

Q. 550
551. But should we not do such things on work-days also? It is well, if any can; but he whom business prevents should at any rate devote holy days to such works.
