"substitution... no basis whatever, either in Holy Scripture or in Christian antiquity."

"The notion of a formal substitution by apostolic authority of the Lord's day [meaning Sunday] for the Jewish Sabbath [or the first for the seventh day]...and the transference to it, perhaps in a spiritualized form, of the sabbatical obligation established by the promulgation of the fourth commandment, has no basis whatever, either in Holy Scripture or in Christian antiquity." - SIR WILLIAM SMITH AND SAMUEL CHEETHAM, "A Dictionary of Christian Antiquities," Vol. 11, page 182, Article "Sabbath."

"This long series of temporal enactments (in considering which we have, for the sake of exhibiting them as a whole, anticipated chronological order) must have told very powerfully upon the conception of the Lord's day in the church itself, not only tending to formalize its celebration, but to invest it in great degree with the character of a sabbath. Still, however, there was no connexion of its observance with the obligation of the fourth commandment, and therefore no application to it either of the laws of the Jewish sabbath, or of our Lord's teaching on the subject, as modifying and spiritualizing these laws." -Id., page 1047
