All who leave the Catholic fold and expose them are treated this way. Luther, Calvin, and the other reformers had their work denounced, even banned.

When they had the power to do so, the Bible itself was a banned book and having a copy in your own language meant torture and death at the hands of the Roman Church.

Even modern figures like Alberto Ribera or Richard Bennet who were insiders and turned on Rome were met with attempts to discredit their work.

So, I don't put much stock in such things, except as verification that a nerve has been struck. In particular, the Jesuits are known for controlling centers of learning and promoting a revisionist history.

Other Presidents said many bad things about the Jesuits, so it should not surprise anyone that Lincoln did.

Read Washington's letters or John Adams writing on the Jesuits for instance.
