Seriously? I seem to recall Jesus, in Luke 6:27, telling us to "Love your enemies, do good to those who hate you."
The Pope is not talking about making "a nice society." He is talking about the way we should show respect, love and grace for others, even for the unbeliever. In that grace-filled encounter is found the opportunity to genuinely share the Gospel.
God's problem with calumny isn't only in the 9th commandment, it is throughout the bible starting in Exodus. 23 Do not spread false reports. Do not help a guilty person by being a malicious witness."
I agree that we should show love to everyone, even people who don’t believe. I just am not going to lie to them about the truth.
