This has become one of my favorite videos from them. While a good deal has already been written about the questionable content and circuмstances of the Divine Mercy devotion (including an excellent writeup by Lee on Introibo's blog right before this video was uploaded), this video goes the extra mile in contextualizing it. I don't know how anyone can defend this devotion after being presented with the overwhelming evidence that this could not have been an authentic devotion instituted by our Lord.
Yes, this is the most comprehensive demolition of Faustina and Divine Mercy that I have seen to date.
Whenever God has revealed such devotions in the past, it has always been to correct some kind of opposite fault. So, for instance, when due to Jansenism trust in God's Mercy was at an all-time low, Our Lord revealed devotion to His Sacred Heart.
Does anybody these days have lack of "confidence" in God's Mercy? In fact, the greatest problem of our day is the presumption in God's Mercy and forgetting about God's Justice.
I can't quite tell if Faustina was just psychologically and emotionally disturbed or whether these were of diabolical origin.
