I had a few questions in my post which were not addressed.
I am not encouraging Orthodox or Catholics to purchase the Monastic Icons.
The charge that they are dangerous, other than that they are blessed in an non-Christian form, which I find difficult to substantiate, is at worst hearsay and at best plausible. One could say it is blessed in a non-Orthodox form for certain, and if there are Catholic iconographers, the same applies that it is non-Catholic form. The main question is regarding them specifically is:
Is there anything within their "artwork" that is heretical?
They may be officially without valid sacraments, they may be doctrinally worse than Oriental Orthodox--being far worse than the charge of Nestorianism. The point in question is in terms of specific danger in the use of their artwork, or if the artwork is blessed by an unsuspecting Catholic elder or Priest (considering if you are a Catholic) or laid on the Altar for forty days by an Orthodox priest (which I doubt would be possible, but I am not ruling out its possibility considering perhaps other companies that make "icon" prints without official iconographers) what really is the danger?
Consider this for a moment... in a practical matter. I own three of their icons. Someone donated these icons to me. I have St. Patrick, St. Francis of Assisi, and St. Joan of Arc. If they are dangerous, these specific "artworks," then I need to throw them away. Let's be very practical about this, since I have a real genuine concern owning three of them.
