That's because Papal infallible teachings are very rare..I think 1857 was the last one. Sometimes it takes a couple generations to realize something was said infallibly. Like contraception and the prophetic declaration by Paul vi in 1968. Now we have the data to support this infallible teaching.Question.......
Has the "one true church" belief ever been declared an infallible Catholic teachings?
Please provide a link to the Catholic church's list of infallible teachings. I don't believe it is there.
If not, then it could disappear tomorrow, just like Limbo and the requirement of Baptism for salvation.
You were raised Catholic, were you not? Free light of Catholicism?
Didn't your friends always get invited to mass with your family??
You should know these basic teachings already. lol
