So Catholics say both are infallible ?
Ex-Catholic here. The bible is a source of knowledge, but the Catechism is the true doctrine. In a way the Catechism is a tradition passed down from generations of popes and laity.
The pope can say something "contradicting" the bible because the pope is what is infallible (not as a human, but with the spirit.) When the pope says something spiritual, it is to be taken as truth, and it is put into the CCC (Catechism of the Catholic Church.) However, if the Cardinals decide that it's out of line with Scripture, or if the Laity believes so as well, they have procedures for handling this. The bible is not what changes, as it is, in it's own way infallible, rather it's the interpretation.
Now, onto another issue, one that allows Catholics to disagree with the pope, I cannot remember the term, but if the Laity, Theologians, and Ministers disagree on a topic, they have a doctrine that allows each member of a congregation to decide with their hearts. However, when homosexuality is brought up by a Theologian or Minister being pro-gay, usually the member is ex-communicated from his position. The Catholic Church is very very specific on what they believe when it comes to sexuality, that is only straight vaginal sex is allowed by their decree. I doubt this will change, which is why I left the church. Their current position however is that it's genetic. However, they will not allow homosexuals into a minister position (other than a deacon... if they had sex at some point they must require three years of celebacy,) they go to the extent of actually monitoring priests to find out if they're gay, if they get suspicious, then you cannot become one. I was going to head into the priesthood, but changed my mind because of such.
