Did you see how baptism is a cross? Learn that even Christ called baptism the cross when He used the name of baptism interchangeably [with that of the cross].
He called your baptism a cross. 'I call my baptism a cross,' he says. Where does He say this? 'I have a baptism to be baptized with, of which you do not know.' And how is it clear that He is speaking of the cross?
The sons of Zebedee came up to Him - rather, the mother of the sons of Zebedee, saying 'Command that these my two sons may sit, one at thy right and and one at thy left hand, in thy kingdom.' A mother's request, even if it was an inconsiderate one!
How then did Christ answer? 'Can you drink of the cup of which I am about to drink, and be baptized with the baptism with which I am baptized?' You see that He called the cross a baptism.
St. John Chrysostom
