Greet all the saints in Christ Jesus. The brothers who are with me send you greetings.
Verse 21. Salute every saint in Christ Jesus. It was usual for him also to close his epistles with affectionate salutations to various members of the churches to which he wrote. These salutations are generally specific, and mention the names, particularly if prominent members of the churches. See the close of the epistles to the Romans; 1Corinthians; Colossians; and 2 Timothy.
Our apostle closes this letter with respectful salutations; he salutes in his own name all and every saint in Christ Jesus; the soul of the poorest and meanest saint was not neglected by this great apostle: he loved the brotherhood, the whole fraternity of believers, the whole society of saints.
God is our Father, not a tyrant or enemy, and we must ascribe to Him the glory of His excellence and mercy, constant and perpetual, forever and ever. Paul's affection for all good Christians moved him to greet not just the leaders but every single saint, and to rejoice that even in Caesar's own household the gospel had borne fruit.
