Mat 22:37-40 Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbor as thyself. On these two commandments hang all the law and the prophets.
How can you say this is not necesssarily a religious concept? Where do you think it came from?
I'm saying it's not exclusively a religious concept. I fully agree that it is one the foundations of Christianity. However, as previously said, "love thy neighbor", where maybe not put exactly that way, is the belief of and followed by most everyone, regardless of their religious affiliation or lack thereof.
