Through Silvanus, our faithful brother, as I consider him, I have written to you briefly, exhorting, and testifying that this is the true grace of God in which you stand.
    In any case the way in which Silvanus is mentioned implies that he was already known to the readers of the Epistle. There is no ground for questioning his identity with the “Silas” of Acts 15:22, Acts 15:32, Acts 15:40, the “Silvanus” of 1 Thessalonians 1:1; 2 Thessalonians 1:1; 2 Corinthians 1:19, the second name having probably been taken, after the manner common among Jews. - CBSC
