They don’t disagree with the Catholic Church that Christ was born on December 25th! They just disagree with the Catholic Church as to when December 25th is!**Oh I get it alright, I get this ridiculous nitpicking about the birth of Christ…who cares? It is what it is…geez…**
If Jesus Christ entrusted the Catholic church to give all of us our bibles, after all, if it weren’t for the Catholic church you wouldn’t have one, then I can safely say that since the church is 2,000 years old, I will rely on it for the birth of our Lord.
For Heaven’s sake, I am Catholic! But the superiority of the Gregorian Calendar to the Julian one is not a dogmatic or even magisterial teaching of the Church, any more than the Church choosing to use Latin is a dogmatic claim that Latin is the best language.
