In the Pardoner's Tale, irony is present throughout the entire story, beginning with the Pardoner himself. What is his official position in the Church?

The Pardoner invites anyone who has sinned to come and offer money to his relics, and therefore to be absolved by the Pardoner’s power. This trick, the Pardoner says, has earned him at least a hundred marks since he was made a pardoner - and when the “lewd peple” are seated, he continues to tell them false trickeries and lies.
