Interesting that OzGeorge and I have been going over this very thing via PMs just before this thread came up (we were discussing it in the old thread before the forum went down). Personally, he's made a great case for the legitimacy of the icon. I'm still not comfortable with it--as in, I'm not going to go out and buy any for myself--because it takes the dove, the Incarnate Christ, and the Ancient of Days Father and puts them all together in one icon. Nice, and if you put two and two together you can come up with that, but the Holy Trinity has never revealed itself specifically and wholly in this manner to the Church. The Ancient of Days appeared in Daniel's vision, so we can depict Daniel's vision. The dove appeared in the Theophany icon (actually, George, didn't you say the Greek said the Holy Spirit descended "as a dove would descend" instead of "in the FORM of a dove"?). Regardless, it seems that these manifestations of the other members of the Trinity are to be left in icons of those actual manifestations.
