You realize that this is just standard Catholicism. Neither Pope Francis, Pope John Paul II, nor Pope Benedict XVI would claim that only Catholics can be saved. The strict belief that there is "No salvation outside of the church" interpreted to literally mean that only Catholics can ever saved is a heresy.

Here is CCC 841:

The plan of salvation also includes those who acknowledge the Creator, in the first place amongst whom are the Muslims; these profess to hold the faith of Abraham, and together with us they adore the one, merciful God, mankind’s judge on the last day.

According to the Catechism, you don't have to believe in Christ or the Bible to be saved.
