This is a Christian, a Catholic monk, a master in theology taking you fight through heresy.
Not that he was a heretic, he lived the Church, more than any man, he lived for God. But he knew God, not only the god that our mind grasp, not the dead concept, but God as he is in himself, alive, and more, he takes us to where this God undress from his ego to become pure and total spirituality.
A most read for anyone serious on mysticism.
And yes, The Inquisition did judge him, found him heretic and burn all his work. He died before the verdict. His work was saved by the anabaptist and reappeared some 6 centuries after having been burned.
We should all be thankful to those who saved his work, since you will never feel God so beautiful as through him
