Because the entire Law covenant, including the command to keep a weekly sabbath, came to its end in Jesus Christ, the apostle Paul could write to Christians: “Let no man judge you in eating and drinking or in respect of a festival or of an observance of the new moon or of a sabbath; for those things are a shadow of the things to come, but the reality belongs to the Christ.” (Col. 2:16, 17)
... Earlier, Paul expressed fear that he had “toiled to no purpose” with respect to certain Christians of the province of Galatia, for they were still “scrupulously observing days and months and seasons and years.”—Gal. 4:10, 11.
