Dionysius of Alexandria

In his own words on Colossians

• Colossians 1:15

  For since of the doctrine, which lately has been set on foot at Ptolemais, a city of Pentapolis, implores and full of blasphemy against Almighty God and the Father of our Lord Jesus Christ; full of unbelief and perfidy towards His only begotten Son and the first-born of every creature, the Word made man, and which takes away the perception of the Holy Spirit,-on either side both letters were brought to me, and brethren had come to discuss it, setting forth more plainly as much as by God's gift I was able,-I wrote certain letters, copies of which I have sent to thee.
