I just wish to confirm that you are aware that St. Basil, in his Hexaemeron, acknowledges that animal death is a pre-fall reality of the natural order created by God. Did you know this?
can you provide the quote? i'd be interested in seeing it. In his follow up work, On the Origin of Man, he explicitly teaches that animal death is NOT a pre-fall reality:
On the Origin of Man, 2:6-7:
‘Let the Church neglect nothing; everything is a law. God did not say: “I have given you the fishes for food, I have given you the cattle, the reptiles, the quadrupeds.” It is not for this that He created, says the Scripture. In fact, the first legislation allowed the use of fruits, for we were still judged worthy of Paradise.
‘What is the mystery which is concealed for you under this?
‘To you, to the wild animals and the birds, says the Scripture, fruits, vegetation and herbs (are given) … We see, however, many wild animals which do not eat fruits. what fruit does the panther accept to nourish itself? What fruit can the lion satisfy himself with?
‘Nevertheless, these beings, submitting to the law of natures, were nourished by fruits. But when man changed his way of life and departed from the limit which had been assigned him, the Lord, after the Flood, knowing that men were wasteful, allowed them the use of all foods; “eat all that in the same was as edible plants” (Gen. 9:3). By this allowance, the other animals also received the liberty to eat them.
‘Since then the lion is a carnivore, since then also vultures watch for carrion. For the vultures were not yet looking over the earth at the very moment when the animals were born;
in fact, nothing of what had received designation or existence had yet died so that the vultures might eat them.
Nature had not yet divided, for it was all in its freshness: hunters did not capture, for such was not yet the practice of men; the beasts, for their part, did not yet tear their prey, for they were not carnivores … But all followed the way of the swans, and all grazed on the grass of the meadow …
‘Such was the first creation, and such will be the restoration after this. Man will return to his ancient constitution in rejecting malice, a life weighed down with cares, the slavery of the soul with regard to daily worries. When he has renounced all this, he will return to that paradisal life which was not enslaved to the passions of the flesh, which is free, the life of closeness to God, a partaker of the life of the angels.’
