I’m going to break protocall and refrute what’s being shown here on the protestant’s behalf even though I am Catholic.
This is a misconception about them not thinking the bible is the word of God. In fact, I’ve been hearing alot on these boards from Catholics where they lean towards it being simply inspired, and not the actual word of God.
Why they don’t believe in the Catholic church is because they are not informed about it as much as they need to be. They have been lied to by their authorities as to the nature of the Catholic church, for if they were told the truth, we would have much less dissention between both sides. This is not to say we have been misinformed about the protestants as well, the is mainly due to a comparison targeted at the fundamentalists, of which are a poor example to use to represent the majority of protestants.
To put it more clearly, we’ll use an example here. Ask a protestant if they believe in creation or evolution, you will find the majority of them lean towards the former rather then the latter. The reason for this is because they believe in what’s written in the bible to be true and literal within the context of Genesis, while we Catholics are debating back and forth on the matter, they have a more unified stance in that regard. There are many instances where both sides are much more in agreement on the elements that matter, ie. the teachings of Christ, his sacrifice, the atonement of sins, God’s love and mercy, etc. That should be something we emphasise when ever we end up in debate with them over all else.
The bottom line here, we can choose to keep the house divided or we can strive towards unity, it’s entirely our call.
