**OF THE SACRAMENTS.**
Now these have been different at different times, according to the dispensation which the Lord has seen meet to employ in manifesting himself to men. Circumcision was enjoined on Abraham and his posterity, and to it were afterwards added purifications and sacrifices, and other rites of the Mosaic Law. These were the sacraments of the Jews even until the advent of Christ. After these were abrogated, the two sacraments of Baptism and the Lord’s Supper, which the Christian Church now employs, were instituted. I speak of those which were instituted for the use of the whole Church. For the laying on of hands, by which the ministers of the Church are initiated into their office, though I have no objection to its being called a sacrament, I do not number among ordinary sacraments. The place to be assigned to the other commonly reputed sacraments we shall see by-and-by. Still the ancient sacraments had the same end in view as our own—viz. to direct and almost lead us by the hand to Christ, or rather, were like images to represent him and hold him forth to our knowledge. But as we have already shown that sacraments are a kind of seals of the promises of God, so let us hold it as a most certain truth, that no divine promise has ever been offered to man except in Christ, and that hence when they remind us of any divine promise, they must of necessity exhibit Christ. Hence that heavenly pattern of the tabernacle and legal worship which was shown to Moses in the mount. There is only this difference, that while the former shadowed forth a promised Christ while he was still expected, the latter bear testimony to him as already come and manifested.
