As I said, the New Testament. Herod wasn't massacring Jews for their Jewishness, he was trying to kill Jesus specifically. Furthermore, even many biblical scholars consider it fictitious and an allegory for the so-called Passover in Egypt. I cannot remember which, but it's only in one gospel anyway.
I'm talking about reality and historical fact, not what is written in ancient literature. For Jewish people, the alleged death of Jesus at their hands (for which there really isn't adequate evidence) lead to shit like the Holocaust. Jesus's coming certainly didn't save the Jews.
Justice is often a subjective notion though and changes over time. In some cultures, it is just to cut the hands from thieves or stone women who have been raped. And it changes over time to reflect values prevalent in different time periods. Justice and notions of it are cultural constructs. Is that what God is too? Does God share the same nebulous and changing nature as our notions of justice?
What would you say Jesus's truth is?
This is precisley the heart of the matter; the way and the truth does not yield to the notion of relative truth, thats why its the Truth. But why is it the Truth? Because it accepts no psychological authority, hence no cultural conditioning. If I accept the authority of the bible or of jesus, I am lost, cause it is but secondhand knowledge that I immitate without grasping, but if one lives with the truth at every instant, a truth born out of observing the heart and mind with deep attention and without any psychological authority placed on one by family and culture and country, all of which are perpetuated by fear, then one will act rightly and justly. Because where there is no fear, no violence, no ambition, there is peace.
How does this work concretley? To watch someone's hands get cut off is painful and messy to watch, so observing those feelings inside of me, I can go on to understand that cutting someone's hands off is wrong because I feel wrong about it, that acts that are violent or born out of retribution are inherintly wrong because they feed the darkness in one. To hurt another is inherintley wrong, because as the Buddah said "If you truly loved yourself, you could never hurt another." That wisdom is aimed at a part of man which man can not understand if he does not first come to know himself and the particular predicament it means to be born of out something we dont know, for a purpose we dont know, towards a destination we shall never know. At the entrence of the Temple of Delphi in Athens is inscribed the maxim "Know Thyself" this being the key to all understanding.
Hence the buddah, jesus, etc, are representatives of the cosmic love and its infinite wisdom which prevades throughout the universe (which is the word, the light, the truth, and the way) all of which are the true nature of the living being, that is to say, all things which reside in every being.
Imagine a child in one of those cultures which cut peoples hands off, thinking "damn this dont feel right, but what can I do, I cant challenge whay my tribe does." Cause the child is unconditioned, uncorrupted, hence why Jesus said "Truly I tell you, unless you change and become like little children, you will never enter the kingdom of heaven." Refering to the purity of children and how their purity is in accordance with truth (truth is the kingdom of heaven, because if heaven exists it would be the ultimate truth, since our whole lives would be meaningless if not for a proper end, just like a movie would me meaningless without a conclusion. Jesus is saying the kingdom of heaven is real~~buddah is saying the kingdom of heaven is real. There can be no proof for that, so Jesus and the Buddah offer the only possible antidote; look inside and you will see heaven, for "as above, so below" said jesus, buddah "“Work out your own salvation. Do not depend on others.” I know its ironic to say dont listen to others while quoting others, but I reckon it balances itself out if I can carry the idea across in these few words.
Thank you for your amazing questions, I hope I have somewhat lived up to their complexity =)
