Romans 14:5-6 : One man esteemeth one day above another: another esteemeth every day alike. Let each man be fully assured in his own mind. He that regardeth the day, regardeth it unto the Lord: and he that eateth, eateth unto the Lord, for he giveth God thanks; and he that eateth not, unto the Lord he eateth not, and giveth God thanks. The sabbath was not the only day set apart in the law of Moses for the children of Israel to observe. Many Jewish Christians still held that the law was binding and demanded that Gen-tile Christians also keep the law. The decrees of the apostles and elders in Jerusalem had no effect on some of them, as Paul's letters abundantly show. Such men would not only be contentious about eating meat, but would demand that Gentile Christians observe the days set apart in the law. In Paul's discussion of these matters of opinion, the Lord's appointments were not included. The Lord has set apart the Lord's day for worship; its observance is therefore not a matter of opinion or indifference. "Let each man be fully assured in his own mind" as to whether he will or will not devote any other day to study, meditation, and prayer. Concerning this the Lord has bound no one, and concerning such matters no one should seek to bind his notions on others. It is therefore evident that the leaders of a church could not adopt these Jewish holidays and demand that all the members observe them. The Judaizing teachers had got in their work among the churches of Galatia, which led Paul to say, "Ye observe days, and months, and seasons, and years. I am afraid of you, lest by any means I have bestowed labor upon you in vain" (Galatians 4:10-11). If the leaders should set any such days to be observed by the church, the members should not submit to such an arrangement. "Let no man judge you in meat, or in drink, or in respect of a feast day or a new moon or a sabbath day" (Colossians 2:16).
