Do only Catholics go to heaven?

I have heard that the Church has said that only Catholics (not Protestants) can go to heaven. Is this true, and if so, what is the basis for this believe?

catrhm,

The following links should assist you in better understanding the Catholic Church’s teaching of extra ecclesiam nulla salus, “outside the Church there is no salvation,” and what that means for non-Catholics. The first link gives the Biblical explanation of what is necessary for salvation. If you have any further questions or concerns that are not answered by these links, please contact Catholic Answers directly.
