Albert Barnes' Bible Commentary
Romans 16 - Introduction
The Epistle concludes with various salutations. The “names” which occur in this chapter are chiefly “Greek;” and the persons designated had been probably inhabitants of Greece, but had removed to Rome for purposes of commerce, etc. Possibly some of them had been converted under the ministry of the apostle himself during his preaching in Corinth and other parts of Greece. It is remarkable that the name of “Peter” does not occur in this catalogue; which is conclusive evidence, contrary to the Papists, that Peter was not then known by Paul to be in Rome.
