"Christ the Author of the Sabbath. - The same being who wrought in the creation of this earth, and the arrangement of it for the habitation of man, who had ordained the marriage institution, and had placed the first human pair in possession of their goodly heritage, was the same one who spent the seventh day in holy rest and contemplation, and thus laid the foundation of the Sabbath for the new-fledged world.
He then blessed the day and set it apart for holy use. Severing it by a boundary which never should be invaded, from all secular time, He dedicated it forever to the worship of Himself, and the memory of His creative work; for,says the record, He sanctified it;that is ,He put it under the guardianship of a definite statue, formulated to regulate its observance.
To "sanctify" means nothing less than this. When Christ declared so emphatically to the people of his time that "the Sabbath was made for man" (Mark 2:27), He knew whereof He affirmed; for He was the very one who performed the acts that made it, and He knew, better than man can know, its object and intent.
Christ Spoke the Law from Sinai. - As the Sabbath law proclaimed from Sinai was but a reiteration of the "sanctification" of the Sabbath pronounced in Eden; and as Christ was the one who there enshrined it in changeless precept for the human family, it follows that he must have been the one, also, who proclaimed it, with the other commandments of the moral law,from Sinai; not,indeed, independently of the Father, but in conjunction with Him, as in all the other works in which they acted conjointly." Uriah Smith
