An former catholic (and anti-catholic) turned evangelical christian blogger here on tumblr posted that catholics added the apocrypha to the bible during the council of trent as a response to the protestant reformation. I was under the impression that these books were already a part of scripture and that they were taken out by protestant reformers? Which is true?
You're definitely correct, and I'm afraid our friend has been seriously misled. Luther and Calvin and Zwingli all write about why they want those books removed from the Bible.
The history is crystal clear if you research it; here's a good link if you want to go deeper.
God bless you!
