Zeke taking the money in a hankerchief

May contain spoilers

When Father John gives Zeke the cabdriver money when they're sitting at the table in the diner, Zeke takes the money in a handkerchief like he doesn't want to touch it, crumbles it up and shoves it in his pocket. Why does Zeke do that? We know that Zeke thinks incorrectly that Father John is involved with the girl and the streets. I thought his taking the cash with the handkerchief was to show that Zeke thinks the priest's money is dirty. Is that what that that gesture was about?
