"The Sabbath is a part of the Decalogue-the Ten Commandments. This alone for ever settles the question as to the perpetuity of the institution...Until, therefore, it can be shown that the whole moral law has been repealed, the Sabbath will stand...The teaching of Christ confirms the perpetuity of the Sabbath."- T.C. BLAKE, D.D., "Theology Condensed," pages 474, 475.

"We must not imagine that the coming of Christ has freed us from the authority of the law; for it is the eternal rule of a devout and holy life, and must therefore be as unchangeable as the justice of God, which it embraced, is constant and uniform."-JOHN CALVIN, "Commentary on a Harmony of the Gospels," Vol. 1, page 277.

"The moral law doth for ever bind all, as well justified persons as others, to the obedience thereof; and that not only in regard to the matter contained in it, but also in respect of the authority of God the Creator who gave it. Neither doth Christ in the gospel in any way dissolve, but much strengthen this obligation." "Westminster Confession of Faith," Chap. 19, Art. 5.

"God instituted the Sabbath at the creation of man, setting apart the seventh day for the purpose, and imposed its observance as a universal and perpetual moral obligation upon the race." ­American Presbyterian Board of Publication, Tract No. 175.
