Print out and study carefully the article by Robert P. Miller, "Chaucer's Pardoner, the Scriptural Eunuch, and the Pardoner's Tale" Speculum 30 (April, 1955), pp. 180-199.
It's quite long, so take your time. But I think you will find it very helpful.
Miller attempts to give what he calls "an Augustinian interpretation" of this Tale.
Compare and contrast Miller's reading with your own reading of the ParT.
