Careful...careful...How is it that YOU know for certain that this man is “delusional, a charlatan, or demonically manipulated?” How is it that you can be so certain that God would not do this? How many have made the same type of judgments regarding the great saints? How can you be so sure that it is mere “nonsense” that has nothing to do with God?
The faithful are not required to believe the boasts of someone who claims to commune with an angel (a manifestation sporting a bad haircut and a crooked grin who is reminiscent of a cartoon character!) nor have there been any great saints who have made such ludicrous claims. Very sad that some are credulous enough to be taken in by this sort of nonsense.
