J Paul said:
"If Our Lady has granted anything to sincere hearts, it is the discernment to see this alien abomination for the sacrilege that it is. "
It is true that Our Lady grants sight to sincere hearts. Unfortunately for you, Nadir and awkward customer and many other "traditionalists", you have not sincere hearts, but are conceited pharisees. Your "catholicism" is selfish and not selfless.
Therefore, you are denied the understanding of the Holy Ghost, who flees from your pride. So much so, that the message through the demon is from Our Lady, yet Nadir says "it verges on blasphemy".
Wisdom 8:4
"For it is she that teacheth the knowledge of God, and is the chooser of his works."
John 8:47
"He that is of God, heareth the words of God. Therefore you hear them not, because you are not of God."
St Father Montfort sums up your position.
"If anyone, therefore, wants to follow me thus abased and crucified, he must glory, as I did, only in the poverty, humiliations and sufferings of my Cross. "Let him renounce himself."
Excluded, then, from the company of the Friends of the Cross are those who take pride in their sufferings; the worldly-wise, the intellectuals and the sceptics who are attached to their own ideas and puffed up with their own talents. Away from you those endless talkers who make a great show but produce nothing but vanity. Away from you those so- called devout Catholics who in their pride display the self- sufficiency of proud Lucifer wherever they go, saying, "I am not like the rest of men;" who cannot endure being blamed without making some excuse, being attacked without answering back, being humbled without exalting themselves.
Be careful not to admit into your society those delicate and sensitive people who are afraid of the slightest pin- prick, who cry out and complain at the least pain, who know nothing of the hair-shirt, the discipline or other instruments of penance, and who mingle, with their fashionable devotions, a most refined fastidiousness and a most studied lack of mortification. You are the members of Christ, a wonderful honour indeed, but one which entails suffering. If the Head is crowned with thorns, can the members expect to be crowned with roses? If the Head is jeered at and covered with dust on the road to Calvary, can the members expect to be sprinkled with perfumes on a throne? If the Head has no pillow on which to rest, can the members expect to recline on feathers and down? That would be unthinkable!
No, no, my dear Companions of the Cross, do not deceive yourselves. Those Christians you see everywhere, fashionably dressed, fastidious in manner, full of importance and dignity, are not real disciples, real members of Christ crucified. To think they are would be an insult to our thorn-crowned Head and to the truth of the Gospel. How many so-called Christians imagine they are members of our Saviour when in reality they are his treacherous persecutors, for while they make the sign of the cross with their hand, in their hearts they are its enemies!"
