Remembering the Law of Moses – Malachi 4:4

If it be asked why he mentions the law only, the answer is obvious, because that saying of Christ is true, that the law and the Prophets were until John. (Matthew 3:13.) It must yet be observed, that the prophetic office was not separated from the law, for all the prophecies which followed the law were as it were its appendages; so that they included nothing new, but were given that the people might be more fully retained in their obedience to the law. Hence as the Prophets were the interpreters of Moses, it is no wonder that their doctrine was subjected, or as they commonly say, subordinated to the law. The object of the Prophet was to make the Jews attentive to that doctrine which had been delivered to them from above by Moses and the Prophets, so as not to depart from it even in the least degree. – John Calvin
