Sorry, the OT from the Christian point of view is not a separate religion from that in the OT.
That's right. 2,000 years after the event the Bible has come to them in its present form and the great preachers of religion lay claim to every work of it, primarily because the religion that Christ came to replace or abrogate chipped away at it until it included the OT as a fundamental aspect of the NT.
It is not. It has its place and its historical connections, but that's it.
As for fulfilling the law, this is not man's law or the general laws found in the OT, this law is the Will of God. That humankind will unite, establish justice and brotherhood, equality of the sexes, removal of all prejudice, remove the massive disparity between rich and poor etc, etc.
You may believe that the OT is a separate religion but from the Christian point of view the bible does not support such a belief.
That's right and just look how well that served them. All the anger and violence and ignorance of science that it spawned. 2018 and people still believe in literal Genesis and Noan's Ark. It's shameful ignorance in a modern world.
promising a sword and in advocating the forsaking of parents
The, sword is the sharpness of the tongue and its words cutting through the ignorance and dogma of the age. Forsaking the parents is a reference to breaking cultural tradition that embeds religious ignorance into the minds of the children. It is written in the OT also that the ignorance of the father will be visited upon the son, crudely paraphrased. Also those who heard these words would have been further instructed to their relative nature, not absolute literal nature.
he would put an end to the "current system of things" The meaning is here that eventually human hearts will dilate and a better, more just, loving, equalised system will replace the unjust system.
As for prophecies about Christ in the OT, they are almost non-existent. The prophecies believed to be a reference to Christ are in fact about the returned Christ who will usher in a completely new religion and have a new name. The returned Christ is not Christ, it is a return of a teacher like Christ, that is why Christ was rejected by the Jews. He did not fulfil any of the prophecies.
You need to ask Christians how they reconcile this anomaly in their sacred texts. Which one, the all have a different story or believe only what they are told to believe.
