When you venerate the Holy Book of another religion it is surely an endorsement of sorts..Will you concede at least that?
Oh sure. It's not like I don't see a problem with it. Whatever we might ascribe to the faults, weaknesses, "diplomacy" or whatever of the man JPII, the photo op alone is scandalous. I just think that an understanding of the former, while not excusing the latter, is helpful in maintaining perspective.
My mother's next door neighbours are Sikhs. They are the most wonderful people I've known. They are more "Orthodox" and "Christian" than any actual Orthodox I've met. They make all their food for the day in the morning and bring a portion over for my mother so that she doesn't have to cook. Because they're vegetarians, and my mom doesn't want to waste the food, she ends up by default observing the canonical fasts more than she ever did when she was in control of her own cooking.
But often, they'll bring over some special food which they offered to their god in their temple. By offering it to the god, it is blessed, and they eat it and give it to others to eat as a blessing. A very eucharistic custom, if you will. But I refuse to eat it. If I know they're going to offer it, I'll make sure I'm not in a position to be offered the food, and if they give it to me, I'll accept it but discard it later; the one occasion where it was inappropriate to refuse, I signed the cross over it and ate, believing that the cross and prayer sanctified it from any "defilement". Is this too scrupulous? My mother thinks so...she'll eat it if she knows it's good, but if it's iffy, she'll pass--false gods don't factor into the question for her. I try to err on the side of caution, even if I could simply sign the cross over everything and eat.
So personally I am careful with things like that, and if I can do that, so can the Pope of Rome. But if there's a "one-off" occurrence where he does something that looks sketchy, perhaps we should look into it a little more before we prepare the fire to throw him upon. It's not like he spent his pontificate kissing Korans: no one's ever seen him do it more than that one time.
