Paul usually included a benediction of grace and peace in his letters. “The God of peace be with all of you. Amen” (Romans 15:33). “The grace of the Lord Jesus be with you. My love be with all of you in Christ Jesus. Amen” (1 Corinthians 16:23-24). “The grace of our Lord Jesus Christ be with your spirit, brothers and sisters. Amen” (Galatians 6:18). Here our greetings convey both human love and divine favor. Paul was not merely talking about a blessing; he was imparting it. In doing so, Paul was drawing on a rich Old Testament tradition. The “blessing” was standard practice among the people of God from the very beginning. Fathers pronounced a blessing on their children, a leader on the people. The blessing was given through prophetic utterance or the change of a name. Such a blessing communicated God’s favor. The loss of blessing was considered a terrible curse, as we learn from Esau, who wept bitterly when his father decided to let the blessing on Jacob remain, even though he had received it under false pretense.
Esau’s cry-“O Father, bless me!”-has echoed through the centuries in the hearts of those who have never received a greeting that carries the blessing of God. Children, parents, spouses, lovers, colleagues and friends want to know that our love for them reflects the love of God, that our love for them channels the love of God. People want to know that God’s favor rests on them. They depend on us, at least in part, to receive that blessing.
Our Christian enemies need that blessing too. I am not proposing that we ignore or dismiss tensions in the church today, but I am suggesting that we mitigate them by praying the favor of God on our Christian opponents whenever we meet them, whether in cordial or adversarial situations. They belong to God, as we do; they believe in God, as we do; they stand in need of God, as we do. The substance of our disagreements might not change, but the spirit of the relationship often will if in our greetings we bestow God’s blessing. We need to remind our opponents that though we differ with them in theology or practice, we still regard them as Christian brethren.
