Keep your apologia for Putin in the appropriate threads. Don't drag it into other threads where it has nothing to do with anything.
Plus, since that is not a direct quote, but from Desmond TooToo, I’ll wait until I see another source.
The quote is a famous one quoted constantly. I have never seen it rebuked as a false quotation of Mother Teresa, but only have seen it praised by various folks who are inclined to ecumenism. Zen Buddhists, Rabbis, and other folks, speak of her "ecumenical" spirit. There is more:
"Some call Him Ishwar, some call Him Allah, some simply God, but we have to acknowledge that it is He who made us for greater things: to love and be loved. What matters is that we love. We cannot love without prayer, and so whatever religion we are, we must pray together."

I don’t disagree with that quote; with the caveat that anyone who thinks the Lord of all is pleased with slaughtering those who use a different name for Him actually are not worshiping God at all. In fact many peoples’ idea of “God” is far from the reality.
People who think that any non-Christian (and even more, those who are not members of their particular denomination) are going to hell are in deep illusion.
