I recall encountering it and wondering, "This is the most sensuous thing I have ever read-What's it DOING HERE?"
Yes, yes, "allegories of Christ's love for His Church", I know, nice try. I seriously doubt anyone who has read it will, at all levels, buy that.
It can also be a little bit hillarious as in one passage the lady (I think) gets so excited that her lover is coming that her bowels moved.
