Alchemy is the forerunner of modern chemistry.
Again, you have no real knowledge of which you claim. I don't need a new convert to the Novus Ordo to "teach" me what the Church teaches, and what you know about mysticism as a new Catholic could fit into a thimble. Concentrate on your own progression rather than critiquing that of others.
You are in over your head. Stop now before you embarrass yourself further.
You show me ONE pronouncement by the Church that this man was a saint, a blessed, or even adhering to the Church's doctrines in what he said and did, and I will concede that we are having a religious discussion and not a historical one. (Since he was declared a heretic and that declaration to my knowledge was never revoked, you're probably going to have a hard time finding any evidence.)
In the meantime, your framing this as a religious/doctrinal issue in order to assert that (as a relatively recent convert to Catholicism) I have no right to an opinion, is simply an attempt to change the subject and an ad hominem attack. I have not attacked you personally or questioned your scholarly credentials, so I would appreciate your returning the favor and sticking to the issue at hand.
Do you have any documented support for your claims?
