From "Against Heresies:"
Those nations however, who did not of themselves raise up their eyes unto heaven, nor returned thanks to their Maker, nor wished to behold the light of truth, but who were like blind mice concealed in the depths of ignorance, the word justly reckons as waste water from a sink, and as the turning-weight of a balance in fact, as nothing; so far useful and serviceable to the just, as stubble conduces towards the growth of the wheat, and its straw, by means of combustion, serves for working gold. And therefore, when in the end the Church shall be suddenly caught up from this, it is said, There shall be tribulation such as has not been since the beginning, neither shall be." For this is the last contest of the righteous, in which, when they overcome they are crowned with incorruption.
Do you need more?
Correct me if I’m wrong but wasn’t Irenaeus a disciple of Polycarp who knew and studied under the very John, himself?
It seems like when you say Irenaus the Christian world should listen. Far more gravitas than Augustine in 386 AD
