Jerome
Catena Aurea · Matthäusevangelium 20
Then came to him the mother of Zebedee’s children with her sons, worshipping him, and desiring a certain thing of him. And he said unto her, What wilt thou? She saith unto him, Grant that these my two sons may sit, the one on thy right hand, and the other on the left, in thy kingdom. But Jesus answered and said, Ye know not what ye ask. Are ye able to drink of the cup that I shall drink of, and to be baptized with the baptism that I am baptized with? They say unto him, We are able. And he saith unto them, Ye shall drink indeed of my cup, and be baptized with the baptism that I am baptized with: but to sit on my right hand, and on my left, is not mine to give, but it shall be given to them for whom it is prepared of my Father.
It is made a question how the sons of Zebedee, James, and John, did drink the cup of martyrdom, seeing Scripture relates that James only was beheaded by Herod, (Acts 12:2.) while John ended his life by a peaceful death. But when we read in ecclesiastical history that John himself was thrown into a cauldron of boiling oil with intent to martyr him, and that he was banished to the isle of Patmos, we shall see that he lacked not the will for martyrdom, and that John had drunk the cup of confession, the which also the Three Children in the fiery furnace did drink of, albeit the persecutor did not shed their blood.
