Q386 - Is a Bishop in Formal Heresy if He Teaches That the Bible Contains Errors?

Yes, because the Council of Trent proclaimed as dogma the inerrancy of the Holy Scripture, and that it was inspired by the Holy Spirit, especially in those truths which concern our salvation.

Of course, there could be in Holy Scripture some inaccuracy in what concerns simply material aspects which are not important for our eternal salvation. In such cases, there could be some inaccuracies or errors regarding purely material information.

However, tradition teaches that the entire Holy Scripture, every part of it, is inspired by the Holy Spirit and is free from any error in what concerns our salvation and those truths that are important for our salvation.
