I'm a Gentile, and St. Matthew was a tax collector.

Matthew 21:28-31 Jesus said to them, "Amen, I say to you, tax collectors and prostitutes are entering the kingdom of God before you.

"I'm a Gentile, and St. Matthew was a tax collector.

Matthew 21:28-31 Jesus said to them, "Amen, I say to you, tax collectors and prostitutes are entering the kingdom of God before you"

But a reasonable interpretation would be that the author was giving practical advice to the christian community, not at all intending a subtle juxtaposition as you suggest. To counsel someone to treat another as a tax collector or a Gentile would be to advise them to avoid that other at minimum.
