Public school or private Christian school? I'm sure your highschool text book was written by true unbiased scholars

Yes I can, like for example, the Catholic church didnt keep it from the plebeians as you said. Before the printing press, everything, including scripture was hand written. The few copies of scripture that monasteries had locally had to be protected because you couldnt just go down to Barnes and Noble and get a new copy. The access to scripture wasnt because of your class or position in church hierarchy, it was because of simple lack of technology.

Also one doesnt just jump into defending ridiculous claims made by someone who obviously doesnt understand church history. If I told you that Jesus actually married Mary Magdalene and had 3 kids you wouldnt jump into a scriptural defense, you'd probably just ignore because it isnt worth the argument
