I am also detecting a pattern from the pope in these things which makes me rather uncomfortable. He starts out saying disconcerting things which just happen to be very popular among those who dislike Catholic social doctrine very much, and then he "clarifies" this in a much less publicised way that only those desperately seeking something less frightening to hold onto will go in search of. This allows the pope to get the support of the left and the anti-traditional, and yet still gives those who are more orthodox an out that they can use to assuage their doubts about him. A win/win, but a bit too political and convenient, as well as being confusing and contradictory if actually looked at closely. I am reminded a bit of the governor in The Best Little W***ehouse in Texas when he keeps saying contradictory things about whether he is going to close down the Chicken Ranch, and we in the pews are like the reporters trying to figure out if what he said meant yes or no. So, is homosexuality a sin? Are atheists saved? Are capitalism and free market economics evil? Well, that's a possible maybe.
I share your concern for the very same reason.
