By What Religious Reasoning Jews & Christians No Longer Believe in Firstborn Birthrights?

Christians are never called the first born that is lie In Exodus 4:22, God declares, "Israel is my first-born son." Peter spoke of Jesus who kept Torah. The first born is the nation of Israel. (The Gospel of Mark) never claims that Jesus is God. Mary even worships God, in Lke 1;46 and calls Jesus a "lord". The characters are based off of the Saducees and Essenes. That is the coming kingdom of God. The idioms of the Bible due to its "Greek" has caused heresy such as Paul and others to misinterpret the actual teaching of Peter. The Gospels are not first detailed account. They aren't the original mcripts. They were possible translated from Aramaic into Greek at a unknown time. Jesus might not even have existed. Peter was a unknown person of origin. It was a message. To keep Torah in the first century. Jesus argues with Pharisees in Jhn 8. The Pharisees kept a "Talmud" not the literal Torah. The Kingdom was of the Judeans but the prophecy of Daniel came to p, the little horn. Which is the Graeco Romans. That is what Jesus fought against and was killed for. Daniel speaks of them in Dan 7;7, and in Dan 9;26, "prince of the people". That is the time the Graeco Romans controlled Jerusalem in the first century AD. It has nothing to do with Jesus being worthy of worship. It wasn't taught in Mark's Gospel. The Trinity wasn't taught either. It was a concept added during the time the Latin version of the Gospels was created.
