Agnus Daily is a relatively new site, and they write excellent Catholic satire, based on real issues within the Church. If you like Maureen Martin's satire, you will love Agnus Daily! Here are a few of my favourites:
Relativism Injures Three
USCCB Approves New Lenten Regulations
Homosexuals in America Urge the Church to Change the Law
And of course the hilarious, Ask Father Fernando
Just click on the topics in their sidebar and get prepared for a few good laughs! A good addition to the blogroll.
