Unite,
Tell me, which of Christ's teachings (Christ being the paradigm of all Christians) were these Christians using to justify their actions:
"Those who live by the sword, die by the sword"?
"love your enemies, and pray for those who persecute"?
"Now that I, your Lord and Teacher, have washed your feet, you also should wash one another's feet. I have set you an example that you should do as I have done for you."?
"A new command I give you: Love one another. As I have loved you, so you must love one another."?
