Ran across this when looking at some Ancient Commentaries on John 21, and thought it was hilarious. I first thought that Gregory must have been Feelin’ the Bern, but then I wondered if this sounded more like the whole “abolish the IRS” crowd. What do you think?
We know that Peter was a fisherman, whereas Matthew was a tax collector. Peter returned to fishing after his conversion, but Matthew did not again sit down to his business of tax collecting, because it is one thing to seek to make a living by fishing and another to increase one’s gains by money from the tax office. For there are some businesses that cannot—or hardly can—be carried on without sin. And these cannot be returned to after conversion.
— Gregory the Great (540-604CE), Forty Gospel Homilies
