“Brethren, I write no new commandment unto you, but an old commandment. . . . Again, a new commandment I write unto you. . . .” (1 John 2:7-8)
On the surface, this passage appears to be a real problem. The easily seen focus of the “commandment” is love for the brethren (vv. 9-11). The difficult wording lies in the “old” and the “new” side of the same thought.
The “old” sense of the command to love is as eternal as the very nature of God Himself. Whatever love we express in our human nature derives its source from God who IS love (1 John 4:16). Even “from the beginning” (1 John 2:7) humanity was charged with the commitment of marital love (Genesis 2:24), which is the earthly example of God’s love for His church (Ephesians 5:25).
Then as God codified His “rules” for those who would submit to His authority, God insisted that we were to “love thy neighbour as thyself” (Leviticus 19:18). Centuries later as the apostle Paul commented on the Mosiac Law, it was noted that “love worketh no ill to his neighbour: therefore love is the fulfilling of the law” (Romans 13:10).
The “new” side of the commandment has its “beginning” with the institution of the new covenant (Hebrews 8:13) and the commissioning of the apostolic leadership (John 13:34). The new focus would be on the spiritual kingdom rather than the earthly nation, and the “brethren” would not merely be genetically related but have a spiritual “new birth”(Acts 10:34-35; Galatians 3:28).
Since “the darkness is past, and the true light now shineth” (1 John 2:8), “he that loveth his brother abideth in the light, and there is none occasion of stumbling in him” (1 John 2:10). This new command goes beyond marriage and nation to the entire family of God. HMM III
