It is proper that the churches should keep such ordinances for the sake of love and tranquillity, so far that one do not offend another, that all things be done in the churches in order, and without confusion, 1 Cor. 14, 40; comp. Phil. 2, 14; but so that consciences be not burdened to think that they are necessary to salvation, or to judge that they sin when they break them without offense to others; as no one will say that a woman sins who goes out in public with her head uncovered provided only that no offense be given. Of this kind is the observance of the Lord's Day, Easter, Pentecost, and like holy-days and rites. For those who judge that by the authority of the Church the observance of the Lord's Day instead of the Sabbath-day was ordained as a thing necessary, do greatly err. Scripture has abrogated the Sabbath-day; for it teaches that, since the Gospel has been revealed, all the ceremonies of Moses can be omitted. And yet, because it was necessary to appoint a certain day, that the people might know when they ought to come together, it appears that the Church designated the Lord's Day for this purpose; and this day seems to have been chosen all the more for this additional reason, that men might have an example of Christian liberty, and might know that the keeping neither of the Sabbath nor of any other day is necessary. There are monstrous disputations concerning the changing of the law, the ceremonies of the new law, the changing of the Sabbath-day, which all have sprung from the false belief that there must needs be in the Church a service like to the Levitical, and that Christ had given commission to the Apostles and bishops to devise new ceremonies as necessary to salvation. These errors crept into the Church when the righteousness of faith was not taught clearly enough. Some dispute that the keeping of the Lord's Day is not indeed of divine right, but in a manner so. They prescribe concerning holy-days, how far it is lawful to work. What else are such disputations than snares of consciences? For although they endeavor to modify the traditions, yet the mitigation can never be perceived as long as the opinion remains that they are necessary, which must needs remain where the righteousness of faith and Christian liberty are not known. The Apostles commanded Acts 15, 20 to abstain from blood. Who does now observe it? And yet they that do it not sin not; for not even the Apostles themselves wanted to burden consciences with such bondage; but they forbade it for a time, to avoid offense. For in this decree we must perpetually consider what the aim of the Gospel is.
