Why do you think Catholics are so determined to lie to everyone about their religion? Why are they so committed to the sin of idolatry?
Because, like the nation of Israel all throughout the Old Testament, the vast majority of them are not regenerate.
I think most don't lie...They just follow the Pied Piper...
I think that priests spend 4 years of formal education to learn how brilliant man's mind is in the form of human philosophy, before they even get to a seminary...And they try to understand the scriptures with their own intellect instead of the spiritual understanding that only comes from God...
They are then subjected to 3 years of Catholic church history, studying what some of the church fathers taught and the Catholic catechism and of course all the rituals that must be observed...
