The Bible, if approached honestly, is clear on the major points of doctrine, with one of the clearest being salvation through faith alone. If people, including any church or its leaders, disagree with this and other clear precepts of Scripture, then, yes, it is absolutely wrong. The RC church turned away from salvation through faith alone and embraced a doctrine of works many years ago. It has been apostate ever since.
Another of the many false doctrines which the RC church teaches is that priests, bishops, etc. are somehow closer to God than the rest of us. In fact, according to God's word, Jesus is the only priest now. He is our only mediator. And, as all false ideas have consequences, the elevation of a priesthood is partially to blame for the lack of accountability for crimes priests commit, and for the average Catholic putting too much trust in people who are merely sinful human beings like everyone else.
