It sounds repulsive at first, but I think I can understand with correct interpretation what it means. Obviously, it's not to be taken literally. To put it in simple terms, it sounds like he's giving a "Snow White" analogy. The crowned prince kisses the bride to wake her up from the effects of the poisonous apple, except this "kiss" turns out to be Christ's death on the Cross. Words like "love affair" may sound repulsive, but we have the book "Songs of Solomon" that is taken allegorically by the Church to represent Christ's relationship with the Church. And then the idea that seems to bring people more repulsive thoughts was "necrophilia," but there's an irony, just as there's an irony to eating Christ's body and blood does not make one a "canabalist," or the irony that the death of an "incarnate God" somehow "conquers death."
I'm not sure how it's "unOrthodox" if interpreted properly. Eutychian? How? How exactly can death occur let alone being nailed to the Cross if Christ was not en-fleshed, or as St. Cyril puts it "en-manned" unless the quote makes it very clear that it was only an imagination, that he really didn't die, or he really didn't feel pain on the Cross, or His humanity is not the same as ours?
Interesting quote though, nevertheless. Good contemplative exercise, imo.
