The Jews therefore strove among themselves, saying, How can this man give us his flesh to eat?
All Commentaries on John 6:52 Go To John 6
John Chrysostom
AD 407
AS they thought it impossible that He should do as He said, i.e. give them His flesh to eat, He shows them that it was not only possible, but necessary: Then said Jesus to them, Verily, verily, I say to you, Except you eat the flesh of the Son of man, and drink His blood, you have no life in you.
