Having only now read to the end of the link I provided, I find in fact that:
The Church of St. Stanislaus Kostka, one of Chicago's famed Polish Cathedrals is home to a nine foot wide Iconic Monstrance of Our Lady of the Sign as part of the planned Sanctuary of The Divine Mercy that is being constructed adjacent to the church. The Monstrance will be found within the sanctuary's adoration chapel which will be the focus of 24-hour Eucharistic Adoration and where there will be no liturgies or vocal prayers, either by individuals or groups as the space will be strictly meant for private meditation and contemplation.
This raises a separate question: How appropriate is the traditional form of the icon itself for the use as a monstrance?
That is, accepting the Latin devotion and usage, is not this icon in a sense made for such a use: a glass pix to accept the consecrated host placed over the circle having the image of Christ? This is not the traditional Latin practice -- using an icon -- but is there anything essentially incorrect or inappropriate?
