That is indeed true, without the Catholic church, you wouldn't even have a bible....there was no one else around for 1,600 years but the Catholics. They did an unbelievable job of compiling the bible out of letters, writings, teachings, old testament documents, historical events, preserving these writings, copying them by hand in Monasteries, keeping them safe from those who would challenge the religion. They were finally available to all (before they were hand copies and too expensive) when the printing press was invented
That a real, lively imagination you've got going there...
