What exactly is your position in denial of the Trinity? Oneness? Jehovah's Witness? Mormon?
Jesus told a man to take up his bed and walk on the sabbath day...so while technically, He did not violate the sabbath day Himself, He did command someone else to violate it...for carrying his mat was work. Therefore He violated it in His teaching.
And yes, Jesus did change the law. I will not dispute that this change can be defined as a transfer. We go from attempting to obey a set of do's and don'ts to walking not after the flesh but after the Spirit, as a law...and of course, if we walk not after the flesh but after the Spirit, the righteousness of the law will be fulfilled in us (Romans 8:4). For there is no law that will condemn us in our behaviour if we bear the fruit of the Spirit (Galatians 5:22-23). Thus, in bearing the fruit of the Spirit we become law-abiding citizens of the kingdom of heaven. This is a righteousness apart from the law that is nevertheless attested to by the law and the prophets that it is righteousness indeed (Romans 3:21); because it is achieved not by attempting to obey a set of do's and don'ts; but rather we obtain the Holy Spirit by faith (Galatians 3:14) and when we walk by the Spirit rather than the flesh, the righteousness of the law is fulfilled in us (again, Romans 8:4, Galatians 5:22-23).
I am also not wrong about Isaiah 9:6. For God is both sovereign and Omnipotent and loving.
Because He is sovereign and Omnipotent, He is able to preserve His unadulterated message in the translation that we know today as the authorized version.
Because He is loving, He was motivated to do so.
And therefore we have an accurate translation in the kjv's rendering of Isaiah 9:6.
Concerning equality with God...the term Elohim is the plural for God and it has been translated as "angels". God is the LORD of hosts and He indwells in all of His fulness each individual member of the host of heaven. Jesus is the chief cornerstone of the building; being the incarnation of the Father and uniquely created as a union of the egg in the womb of the virgin Mary and the Holy Ghost.
The Most High is the Spirit that indwells every member of the host of heaven in all of His fulness. Every angel is subject to the Most High; and yet inasmuch as each one has the fulness of the Lord dwelling within him, and his spirit is made one with the Holy Spirit, his spirit is made equal to the Most High God, while in his created angelic form he is less than equal to the Most High.

The apostles who wrote the gospels were in fact eyewitnesses of Jesus' life, death, burial, and resurrection, it was all in the timeframe where that is possible.
