Answer:
the Pope’s authority
Passage: But, sirs, there’s one thing I forgot to add:
I’ve got relics and pardons in my bag
As good as anybody’s in England,
All given to me by the Pope’s own hand.
If any here should wish, out of devotion,
To make an offering, and have absolution,
Let them come forward now, and kneeling down
Humbly receive my blessing and pardon.
