Did Christ ever advocate violence against non-Christians?

All Forget that The Son was Representing the Father so were is your Point? Jesus also said He and the Father are One. That to See Him(Jesus) was to See the Father. So you are going to accept or represent that Jesus is Good but the God in the old testament is Evil? Jesus did in fact show the Love God has for us ALL even those who are Evil which Jesus also said was ALL including Him(Jesus). He did say not to call even Him(Jesus) Good for ALL have fallen from Grace and ALL have Sinned. Yet some would have Jesus portrayed as different from the Father. When Jesus comes back to set the World Right He will bring the Sword of Truth which is the Word and He is the Word. So? Your Point is?

Only we Catholics have kept the pericope of the Adultress as Scripture (Ehrmann calls this the most popular of all pericopes, from his experience) and Jesus there resists the hardest of all violences to resist, that which invokes the law.
So the answer is 'NO'
Though another book (ony preserved by Catholics, Judith) does show that civil authority can bring about public enemies such as a Hitler of our day, And that is justice for sure.

But I am a Catholic and atheists on here are so afraid of Catholic clarity thaty they use words like 'religionS' [plural] so they can create a mishmosh that has NO adherents.

This is about the authority of the Catholic Church but there is no dispassion in that discussion !!

Keep in mind that a "Christian" is one who follows the teachings of Christ and aspires to model oneself as Christ. The Old Testament is a pre cursor to "Christianity". God made a new covenant with his followers contained in the New Testament. The Old Testament is included in the Christian Bible for historical and contextual background. The New Testament is Christianity manifesto. Hope this helps to clarify. The Koran and Hadith has no such "new covenant" It is all progressive revelation in which Muhammad gets more ruthless , violent and power hungry.

That is about as clear an explanation of Christianity as I have ever seen.

But Liberals use political correctness (first the Muslim, then the Jew) to control the US as their 3rd world political ( not medicinal nor mechanical) state.

Absolutely not. This is man's human nature. If one is to understand the truth one needs to ask Jesus for the truth. The truth is soul is not from here, is man's higher intelligence and man was created a vessel for soul to transform within by the renewing of the mind and Jesus has made the way ready for you to go. There is no violence along the way with Jesus, and the way is how we remain in the world walking the law of the land in peace and love harming. no one not even ourselves. Anyone who harms another is doing so because of ego. Ego is man's personal god, came into being through the mingle of soul and the instinctual spirit.
