Brother, whose praise is in the gospel, through all the Churches. [2] It may either signify in writing or in preaching the gospel, so that though St. Jerome expound this of St. Luke, who wrote his gospel, (but probably not till after this time) yet St. Chrysostom rather understands it of Barnabas, by the words that follow, who was ordained by the Churches companion of our travels. Others also guess it might be Silas or Silvanus. Who the third brother was, is also uncertain. (Witham) — Commentators very in their opinions upon the person here mentioned. St. Chrysostom and Theo. are of opinion, that this person is St. Luke or Barnabas; St. Jerome also thinks that it must be St. Luke the evangelist.
