or SYLVANUS, was, according to St. Luke, Acts 15:22 , one of the "chief men among the brethren," which makes it probable, that he was of the number of the seventy disciples. When a dispute was raised at Antioch about the observation of the legal ceremonies, they chose Paul, Barnabas, Judas, and Silas, to go to Jerusalem, to advise with the Apostles concerning this question. He is thought to be the same Silas who is mentioned by the name of Sylvanus, in the title of the two epistles of St. Paul to the Thessalonians. St. Peter sent his first epistle by him from Rome, wherein he styles him "a faithful brother." Silas joined himself to St. Paul; and after Saul and Barnabas had parted, on account of John Mark, Acts 15:37-41 , Silas followed St. Paul, and went with him to visit the churches of Syria and Cilicia.
