“Wherefore I also, after I heard of your faith in the Lord Iesus, and loue vnto all the Saints,”
1611 King James Version (KJV)
1:15 Since I heard of your faith and love - That is, of their perseverance and increase therein.
Eph 1:15 After I heard of your faith in the Lord Jesus. This verse has been thought to show that Paul was not personally acquainted with those to whom he wrote, and hence that this letter could not be addressed to the Ephesians; but he used similar language of Philemon, one of his own converts. See Phm 1:5. The language is natural if Paul left Ephesus in the spring of A.D. 57, and wrote this letter about the close of A.D. 62 (Conybeare and Howson), more than five years after. During this period he could only know of the faith and love of the Ephesians by what he heard.
