I don’t mean to be too serious in a thread that I realize was started for fun; but…
Being a Traditional Catholic is more than a preference for certain traditional devotions, or even for the Traditional Mass. Being a Traditional Catholics means thinking as the Church has always thought. In other words, being a Traditional Catholic means having the real faith with no admixture of liberalism or modernism which are the errors of our day.
So, how do you know if you are a Traditional Catholic? The answer is simple. You know *for sure *that you are a Traditional Catholic when you can read the pre-Vatican II papal emcyclicals that disucss Liberalism and modernism and find them to be a joy, and an expression of exactly what you still believe. That is how you and I can know if we are Traditional Catholics.
What are some of these enyclicals?
1.) Mortalium Animos, Pius XI
2.) Libertas, Leo XIII
3.) Quanta Cura, Pius IX
4.) Humani Generis, Pius XII
5.) Mirari Vos, Gregory XVI
6.) Pascendi, Pius X
7.) Satis Gognitum, Leo XIII
These are some of the pre-Vatican II encyclicals that condemned many of the modern errors we have today. If you read these enyclicals and think to yourself - YES!

- as you are reading them, then you know you are a Traditional Catholic.
An even better test (since it is more concise) is to read the book
Liberalism is a Sin. This books does a very good job in explaining the subtle errors of Liberalism. It is a book that the Liberals of the day hated, and the Pope and Holy Office praised.
