Hilary of Poitiers
Catena Aurea · Matthäusevangelium 17
And his disciples asked him, saying, Why then say the Scribes that Elias must first come? And Jesus answered and said unto them, Elias truly shall first come, and restore all things. But I say unto you, That Elias is come already, and they knew him not, but have done unto him whatsoever they listed. Likewise shall also the Son of man suffer of them. Then the disciples understood that he spake unto them of John the Baptist.
As he announced the Lord’s coming, so he was also to foreshew His passion by the example of his own suffering and wrong? whence it follows, So also shall the Son of Man suffer of them.
