If one really wants to get technical, judging others, having a self-righteous attitude, a hateful heart, etc, are all exceedingly worse than any physical sin one could ever do. Christ illustrated this point in the parable of the Tax Collector and the Pharisee (Luke 18:9-14).
Christ commands us to love our enemies. I'd take what Christ says over the words of a man.
Mark 12:29-31
Jesus answered, “The foremost is, ‘HEAR, O ISRAEL! THE LORD OUR GOD IS ONE LORD; AND YOU SHALL LOVE THE LORD YOUR GOD WITH ALL YOUR HEART, AND WITH ALL YOUR SOUL, AND WITH ALL YOUR MIND, AND WITH ALL YOUR STRENGTH.’ “The second is this, ‘YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF.’ There is no other commandment greater than these.”
Luke 6:35
But love ye your enemies, and do good, and lend, hoping for nothing again; and your reward shall be great, and ye shall be the children of the Highest: for he is kind unto the unthankful and to the evil.
1 John 4:8
Whoever does not love does not know God, because God is love.
1 Cor 13:4-8
Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres. Love never fails...
We're quick to join 1 John 4:8 and 1 Cor 13 when discussing the salvation of all, but then we do exactly what the churches do (contextualize it away) when it comes to the idol of hatred.
In Him,
John
