Tacking on anyone or anything to the apostolic message is pure and mindless imitation of ancient Israel. God’s will, as performed by the Lord Christ, is also his (will and) testament. Christ’s death changes everything: the covenant, the glory and the adoption. By dying he opened the way into God’s family and he left no stone unturned.
Wisdom, righteousness, sanctification and redemption
“But by His doing you are in Christ Jesus, who became to us wisdom from God, and righteousness and sanctification, and redemption, so that, just as it is written, “Let him who boasts, boast in the Lord.1 Corinthians 1:30-31, NASB
What else can people be legitimately interested in? A phony kind of love seems to be a popular target, but loving God apart from loving people is an abortion pill.
The law is not enough
Of all the things Christ could be for humanity Creator and prosecutor are a couple for which we need no fanfare. Maybe one for the upcoming creation; but what purpose does that serve in the current season of earth’s history? Definitely no fanfare for Christ as prosecutor. That role he leaves with Moses. Yes, Christ cannot simultaneously be the accuser and defense lawyer. The diabolic nature of the false teaching about Christ as inscribed of the Sinai Covenant on human hearts can hardly be more graphic. Nobody gets the Holy Spirit from Christ because they kept the law of Moses, neither ten Commandments, nor statutes nor judgments. It has to be a demon who tells people that they, having received the Spirit of apart from any kind of law, need the law to maintain the new status.
Who, if not the Nazarene?
Despite the expulsion from Eden and the flaming sword blocking the way back, God’s actions demonstrated his primary interest in the preparation of the family through which his Son would be born. God did not expose Abraham to Melchizedek or include Rahab in the family that moved into Canaan because he wanted to create a racist heaven in Canaan. The law, the kingdoms of Israel and Judah, their expulsion from Canaan, the destruction of the temple were obviously not feathers in Moses cap. As Luke says, the convincing proofs (Acts 1:3) of Christ’s identity and our destiny are within reach of all who care sufficiently to give a little attention to the narratives of the Risen Christ. Of course, he is enough.
