There is a real issue here. I will make use of an analogy:
When someone wants to preach about marriage, he doesn't speak about it's hard side: washing tones of dishes, chance of being a widow(er), chance of losing a child, doing laundry, quarreling etc. etc. He just speaks about romance, love and perfumed red roses. in order to attract you to this sacrament. IT IS ALSO THE CASE WITH OUR FAITH:
Our Holy Religion, specially it's mystical/ascetical aspect may be scandalous and shocking to many people, it is why many preachers do their best to hide these aspects. Lest men should be shocked.
Once I posted some thing on this forum about St. Ludwina's actions. People told me that it was wrong and a malarkey. However that incident was recorded in her biography.
Predestination and repobration too, are matters of faith. Yet I saw that priests are tend to avoid answering people's question about repobration. They are good willed, they are afraid lest someone succombe to despair and defidence after hearing about it.
Saints have done many things that we may call crazy. Some of them used an erotic language when speaking about our Lord, though you may think it blasphemous. Some of them really acted like a puritan, hating the world their body and avoiding any pleasure.
When catholic pastors avoid talking about this matters, they are just giving an apportunity to atheists to say :" Look the church is hiding this from you" ," come and see what they are hidding from you for 2000 years."
It is like what I said about marriage.
If you want to attract people to any thing, don't speak about it's hard to accept aspects!
