John Calvin on Ephesians 6:23

23. Peace be to the brethren. I consider the word peace, as in the salutations of the Epistles, to mean prosperity. Yet if the reader shall prefer to view it as signifying harmony, because, immediately afterwards, Paul mentions love, I do not object to that interpretation, or rather, it agrees better with the context. He wishes the Ephesians to be peaceable and quiet among themselves; and this, he presently adds, may be obtained by brotherly love and by agreement in faith From this prayer we learn that faith and love, as well as peace itself, are gifts of God bestowed upon us through Christ, — that they come equally from God the Father and the Lord Jesus Christ.
