I never have believed in god in any real sense but, since I was educated in Roman Catholic schools, (3 - from mid 60's to late 70's) I feel I should defend them a little. Firstly, it's Protestants, more than Catholics, that believe the in-errancy of the bible. Catholics generally recognise the historical and scientific errors, at least. For Catholics authority comes from the bible, the catechism, from the apostles and their successors (bishops), the authority of the pope, the tradition of the church. Very few Catholics would punctuate a conversation with "but the bible says". Evolution, archaeology, physics are not incompatible with Catholic tradition. I, for example, was taught 'A' Level Biology by a monk. The new pope isn't suddenly out of step with what went before.
It would be better if they changed their minds about contraception and sexuality though.
There is some discussion in that direction:
