Irenaeus

I am quite aware that some persons endeavour to refer these words to the case of savage men, both of different nations and various habits, who come to believe, and when they have believed, act in harmony with the righteous. But although this is [true] now with regard to some men coming from various nations to the harmony of the faith, nevertheless in the resurrection of the just [the words shall also apply] to those animals mentioned. For God is non in all things. And it is right that when the creation is restored, all the animals should obey and be in subjection to man, and revert to the food originally given by God (for they had been originally subjected in obedience to Adam), that is, the productions of the earth. But some other occasion, and not the present, is [to be sought] for showing that the lion shall [then] feed on straw. And this indicates the large size and rich quality of the fruits. For if that animal, the lion, feeds upon straw [at that period], of what a quality must the wheat itself be whose straw shall serve as suitable food for lions?
