Your grandmother was judging those at her church? For shame!
It’s in the Bible somewhere. Right near the passage that says providing support and giving power to those who abort babies is the surest path to heaven. In fact, you get beamed straight up and don’t even have to check in with St. Peter.
I can’t think of the passage right now but a lot of posters seem convinced it’s there, so I’ll go with that.
She was actually pointing out to her children the hypocrisy of those who profess to be the most Pious, her point in doing so was to give the message to her children that if you're going to be Pious in Church you better be the same outside of it, if not then do the best you can inside and outside of Church. My Grandmother believed in a good loving forgiving God.
And while we're at it, we have people being murdered everyday in our Country and around the world, we have people in parts of the world being starved by their own leaders, do we seriously think people voting for the presumptive Republican nominee are God's priority?
