"_A._ The Scripture commands us to hear the church (Matt. 18:17; Luke 10:16), and to hold fast the traditions of the apostles. 2 Thess. 2:15. But the Scriptures do not in particular mention this change of the Sabbath." In the "Doctrinal Catechism," we find further testimony to the same point:-- "_Ques._ Have you any other way of proving that the church has power to institute festivals of precept? "_Ans._ Had she not such power, she could not have done that in which all modern religionists agree with her--she could not have substituted the observance of Sunday, the first day of the week, for the observance of Saturday, the seventh day, a change for which there is no scriptural authority." And finally, W. Lockhart, late B.A. of Oxford, in the Toronto (Cath.) _Mirror,_ offered the following "challenge" to all the Protestants of Ireland; a challenge as well calculated for this latitude as that. He says:-- "I do, therefore, solemnly challenge the Protestants of Ireland to prove, by plain texts of Scripture, the questions concerning the obligation of the Christian Sabbath. 1. That Christians may work on Saturday, the old seventh day. 2. That they are bound to keep holy the first day, namely, Sunday. 3. That they are not bound to keep holy the seventh day also." This is what the papal power claims to have done respecting the fourth commandment. Catholics plainly acknowledge that there is no scriptural authority for the change they have made, but that it rests wholly upon the authority of the church; and they claim it has a token or mark of the authority of that church; the "_very act of changing the Sabbath into Sunday_" being set forth as proof of its power in this respect. For further testimony on this point, the reader is referred to a tract published at the _Review_ Office, Battle Creek, Mich., entitled, "Who Changed the Sabbath?" in which are also extracts from Catholic writers, refuting the arguments usually relied upon to prove the Sunday Sabbath, and showing that its only authority is the Catholic church. "But," says one, "I supposed that Christ changed the Sabbath." A great many suppose so; and it is natural that they should; for they have been so taught. And while we have no words of denunciation to utter against any such for so believing, we would have them at once understand that it is, in reality, one of the most enormous of all errors. We would therefore remind such persons that, according to the prophecy, the only change ever to be made in the law of God, was to be made by the little horn of Dan. 7, and the man of sin of 2 Thess. 2; and the only change that has been made in it, is the change of the Sabbath. Now, if Christ made this change, he filled the office of the blasphemous power spoken of by both Daniel and Paul--a conclusion sufficiently hideous to drive any Christian from the view which leads thereto.
