I was originally planning to release the Oath Against Modernism today, but it ran quite long as I decided to do both English and Latin so I'm going to share that with you all tomorrow. Thank you for understanding!

Pius X's "Sacrorum Antistitum", condemning modernism (includes the Oath Against Modernism):

The Catholic Encyclopedia, "Modernism":

I *think* this link will take you to the relevant section of an online version of the New Catholic Encyclopedia (namely their section on Modernism), but I've been more confident in my life. Don't give it your credit card information, as what I have in mind won't ask for that. Anyways:
