Cyrill of Alexandria
Cyril. Concerning both sheep and goats, He establishes a singular principle; the same sacrificial rite applies to both, demonstrating the differing sizes of the animals as a striking representation of the devotion and honor of those presenting the offering. One animal, being plentiful and superior in piety, can be seen as a representation of the calf; another, of average quality, corresponds to the sheep; while yet another, even less, is the goat, which is smaller than the sheep. This, I believe, reflects the teaching of the Gospel parable, where the fertile soil yields fruit in 'a hundred', 'sixty', and 'thirty' (Matt. 13:8:23). Palladius. Concord.
