May I remind you that the writers of scripture were Jews. Catholics trying to take credit is laughable. One only needs to compare the Douay-Rheims Bible to the Hebrew and Greek text to see they couldn’t even get translation done correctly.
of course they were Jews....until they became followers of Christ and then they were Christians....and the first Christians became referred to as Catholic or universal because they had been charged to go forth and teach all nations....see how it all fits together??
