1 John 2:7
7Brothers, I write no new commandment to you, but an old commandment which you had from the beginning. The old commandment is the word which you heard from the beginning.
No new commandment, but old—the word heard from the beginning. Wesley: not any new one; they had it even from their forefathers.
Love is not a novelty John invented. The same word that began with them still binds. Newness will be in the next verse’s fulfillment, not in a replacement law.
Calvin: he taught nothing respecting love but what had been heard from the beginning. Novelty is disliked; an unwonted yoke is not easily taken. Old here is first elements of the gospel, taught from their new entrance into religious life.
This proceeded from Christ Himself. Antiquity is not superstition’s age but Christ’s own first word to them.
