Everyone may criticize Francis for saying what obviously needs to be said, but this is straight from the Bible. Jesus said it himself when he said something along those lines. It was in his sermon on the mount, I think.
Would you mind clarifying your words with some Biblical examples?
Sure, no problem.

You can tell a true doctrine from a false one by the emphasis on which world takes precedence.
