Colossa was a city of Phrygia, near Laodicea. It does not appear that
St. Paul had preached there himself, but that the Colossians were
converted by Epaphras, a disciple of the Apostles. However, as St. Paul
was the great Apostle of the Gentiles, he wrote this Epistle to the
Colossians when he was in prison, and about the same time that he wrote
to the Ephesians and Philippians. The exhortations and doctrine it
contains are similar to that which is set forth in his Epistle to the
Ephesians.
