“Out of respect and honor for Matthew, the other Evangelists did not wish to give him his usual name. They called him Levi; for he had two names. But Matthew (according to the saying of Solomon, ‘The just man is the first to accuse himself,’ and again, ‘Confess your sins that you may be justified’) calls himself Matthew and a publican, to show his readers that no one need despair of salvation if he is converted to better things, since he himself was suddenly changed from a publican into an Apostle.”
