Only for the first one. Sequels are planned and will be true to the books (except for substituting magisterium for catholicism)
I don’t know if there will be any sequels at this point.
While it's true that most people --- including most Catholics --- don't know what a "magisterium" is, it's a distinctively Catholic word in the same way that say, "Talmud" is distinctivelty Jewish or "Sharia" is distinctively Muslim.
But would they make a children's movie based on the supposedly utter depraved wickedness of the "Talmud" or of "Sharia"? The question answers itself.
