Presented above is a revised version of the Papal Arms of Benedict XVI which takes into account developments since his accession to the Papacy. You can catch up on the original here. The revised symbolism is blindingly simple:
St. Alphonsus Luguori: patron of theologians and founder of the Redemptorists.
The Vulture: picking away at Vatican II
The Conche: an admonition to listen to the sea rather than the See.
