"Christianity is not, and never has been, an unchanging monolith. No dogma, no text, not even one’s favourite biblical text, is God’s command to everyone at all times. No single source is infallible. In every age we bring the resources available to bear on the issues we face. Our understanding is always limited and uncertain. The only people who are certainly wrong are the ones who claim to be certainly right. Such people become intolerant and deaf."
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 neighbour as thyself. On these two commandments hang all the law and the prophets.
If Matthew xxii:37-40 is correct then I must love God and my neighbour in the appropriate manner.
