Just War Theory redux:
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.
– Matthew 22:37-40
How are we to love ourselves, and, ergo, our neighbours?
Wherefore if thy hand or thy foot offend thee, cut them off, and cast them from thee: it is better for thee to enter into life halt or maimed, rather than having two hands or two feet to be cast into everlasting fire. And if thine eye offend thee, pluck it out, and cast it from thee: it is better for thee to enter into life with one eye, rather than having two eyes to be cast into hell fire.
– Matthew 18:8-9
Yes sir, the Lord is a man of war (Exodus 15:3). That’s why they call it the Church Militant. Clear?
But, don’t get cocky, kid. NB, if you don’t start with loving yourself properly first, it’s cheating.
Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother’s eye.
– Matthew 7:5
