Didn't Jesus tell them of their final Judgement? Is that not more final and eternal than killing?
If you believe in Judgement, how might you think Jesus would have Judged those who would have simply permitted the Waldensians to go to hell in their own handbasket unopposed?
Jesus said it might earn the Fathers approval as He would call such His children:
That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust. (Matt. 5:45) The preceding verses may be enlightening to you also!
What do you think that preaching the Gospel and practicing the Beatitudes and Christian life is for? An exercise only? Or is it for the purpose of rescuing others from the grave of hell?
You’re going far afield from what I said.
To repeat:
By what teaching, by what example or principle of Jesus or his apostles are Christians authorized to use threats of death or harm against those who did not agree with them?
How is it anyones duty to persecute the Waldenses or any other group in Christs name?
Is it really that difficult a question?
