{The God of peace} (ho theos t(8873) eir(886e)(8873)). One of the
characteristics of God that Paul often mentions in benedictions
( 1Th 5:23  2Th 3:16  2Co 13:11  Php 4:9  Ro 16:20 ). Because of
the "amen" here some scholars would make this the close of the
Epistle and make chapter 16 a separate Epistle to the Ephesians.
But the MSS. are against it. There is nothing strange at all in
Paul's having so many friends in Rome though he had not yet been
there himself. Rome was the centre of the world's life as Paul
realized ( 1:15 ). All men sooner or later hoped to see Rome.
