Dear Griego,
O.K., I'll stay for a little while longer!
The icons that portray the adult Christ standing in Chalices reflect theological truth only.
There are those that do portray Him as a Child and these, according to Mohyla, do indeed represent the experiences of priests and bishops over the centuries via Eucharistic Miracles.
Joan Carroll Cruz, as we know, wrote an excellent book on Western Eucharistic Miracles.
I've never known of any collection of such in the East and there is a good reason for this.
The Eucharistic Miracles, for the East, are always, as Mohyla also states, a "negative" expression of God's anger at, for example, a lack of faith in the fundamental miracle of Transubstantiation/Transmutation of the elements, or of a lack of respect for the Eucharist etc.
The Eucharistic Miracle in the East is ALWAYS an expression of God's displeasure, including the Lanciano miracle.
I daresay having read Cruz's book, there is also not one such miracle that is not likewise connected to an act of disrespect or blasphemy against the Holy Eucharist.
For example, when the priest who was in a hurry to bring the Eucharist to a sick person, placed a consecrated Host between the pages of his prayerbook (!) and closed it as he rushed off.
When he got to the home of the ill person and opened his prayerbook, he saw that the Host had MELTED into Blood - the stained pages are still on display, as Cruz recounts.
It is also true that of all the miracles that occur through miraculous icons and images etc., Eucharistic Miracles are, by far, the most numerous - but they are not nearly as widely reported as the others are.
And for that reason - no one wants to point themselves or others in their parish out as having occasioned such a miracle through lack of fervour or belief in the Eucharist.
