I believe what this priest is saying is entirely possible. Reminds me of the warnings from the Akita apparitions.

"The work of the devil will infiltrate even into the Church in such a way that one will see cardinals opposing cardinals, bishops against bishops. The priests who venerate me will be scorned and opposed by their confreres…churches and altars sacked; the Church will be full of those who accept compromises and the demon will press many priests and consecrated souls to leave the service of the Lord.
I think instead of writing this guy off we ought to take it as a reminder to pray like we never have before for those in charge of our Church. In one way or another, they ARE under attack and a target by Satan. They need our prayers.
