In the 1st Century A.D. See: Mt. 12:1-8; Mk. 2:24-26; Lk. 6:1-5; John 5:10-11. Jesus cured on the Sabbath [John 5:10-11]. He also declared Himself to be Lord of the sabbath: "the Son of Man is Lord of the Sabbath" [Lk. 6:5]. St. Paul also told the Colossians not to "let anyone condemn you in matters of food or drink, observing festivals . . .Sabbaths." [Colossians 2:16-17] Why?

"Sunday is a Catholic institution, and... can be defended only on Catholic principles... From beginning to end of Scripture there is not a single passage that warrants the transfer of weekly public worship from the last day of the week to the first." Catholic Press, Aug. 25, 1900 "The Sabbath was Saturday, not Sunday. The Church altered the observance of the Sabbath to the observance of Sunday. Protestants must be rather puzzled by the keeping of Sunday when God distinctly said, 'Keep holy the Sabbath Day.' The word Sunday does not come anywhere in the Bible, so, without knowing it they are obeying the authority of the Catholic Church."
Neither the Catholic church nor Christianity at large consider Sunday to be the Sabbath. Differing denominations have differing views on why we have church gatherings on Sundays, but we don't do it out of a mistaken view on the Sabbath.
