Fisher’s Catechism Q. 63. How do you prove that national covenanting is a warrantable duty under the New Testament?
A. From its being promised in the Old Testament that this shall be a duty performed under the New, Isaiah 19:21 — “The Egyptians shall know the Lord in that day, and — they shall vow a vow unto the Lord, and shall perform it.” Besides, if it was a moral duty upon special occasions, under the Old Testament (as appears from 2 Chron 15:12, and 34:31, 32; Neh. 9:38), it must remain to be the same, upon the like occasions, still; because Christ came not to destroy the law or the prophets, but to fulfil them, Matt 5:17.
