I have never read that but wonder if, as with Padre Pio, did Dom Camillo tell others of these experiences during his lifetime? If he did, there would be somewhat of a record of sorts of first-hand, primary witness testimony to this following him throughout his life o lend support. All of what we know from Fr. Michel is what he has told us himself, correct or not? I haven’t heard of anyone from his past attesting to the fact that Father has had the types of communications he claims to have had with God the Father, Our Lord, Our Lady, etc. throughout his life. So, unless someone fills me in on this SPECIFIC thing (no tangents, please!), then I am forced to rely solely on his word.
