John Chrysostom
Catena Aurea · Johannesevangelium 10
And it was at Jerusalem the feast of the dedication, and it was winter. And Jesus walked in the temple in Solomon’s porch. Then came the Jews round about him, and said unto him, How long dost thou make us to doubt? If thou be the Christ, tell us plainly, Jesus answered them, I told you, and ye believed not: the works that I do in my Father’s name, they bear witness of me. But ye believe not, because ye are not of my sheep, as I said unto you. My sheep hear my voice, and I know them, and they follow me. And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand. My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father’s hand. I and my Father are one.
(Hom. lxi. 2) He reproves their malice, for pretending that a single word would convince them, whom so many words had not. If you do not believe My works, He says, how will you believe My words? And He adds why they do not believe: But ye believe not, because ye are not of My sheep.
