Origen

“ And at a time when there was no knowledge among men of the mystery of the Gospel, those who were greater than men and inhabitants of heaven, the army of God, praised God, saying, “Glory to God in the highest, and on earth peace, good will among men.” ”

“ The Angels Also are Evangelists.
Now if there are those among men who are honoured with the ministry of evangelists, and if Jesus Himself brings tidings of good things, and preaches the Gospel to the poor, surely those messengers who were made spirits by God, [1] those who are a flame of fire, ministers of the Father of all, cannot have been excluded from being evangelists also. ”
