I "carp" about how priests know nothing about sexual relationships and have little idea of real intimacy? Pray tell, when did I do that? I do believe you are winging it or throwing your pasta at the ceiling again. Or maybe just lying? 


I hold Andrew Greeley in some regard for his intellectual abilities and sociological studies on the RCC and in areas such as that of the relationship between churches and social capital. I would not consider him any go-to writer on sexuality except in terms of religious metaphoric writing. I give him lots of cred for making the sacraments representative of actual life by focusing on life and relationship. I don't find his writing particularly deep and broad, but, rather, in a genre of religious romantic writing, albeit in a deeper sense of romantic than romantic novels. Fr. Greeley is not of such 'extremely liberal bent' as you think, but, perhaps, if you are pretty sheltered in your reading?
