Well, belief is not relevant to me. I am not talking about my belief and faith here.
Also, according to your own faith, making Paul a disciple of Jesus, and you saying Jesus himself walked with and beyond the Torah, basically and ultimately Paul is in in conflict with the Law. You have been affirming the same with your faith so far.
It does not necessarily have anything to do with belief. You are criticizing Text of the Bible. Regardless if you believe in God, Christ, or even existence of Paul:
The Question is:
According to Gospels, did Jesus reduce or change some of the Laws of old testament or not?
The Quran says Jesus reduced Laws of Torah with permission of God.
Again, regardless if you believe Quran is word of God or not, the understanding of the Author of Quran is, Jesus did reduce the Laws of Torah.
So, i wouldnt say Paul is in conflict with Law. I would say, His understanding was compatible with Jesus. In another words, Paul did not deviate from Jesus theology.
Now, according to old testament, could God reduce or change the Laws of Torah if He wants to? Could God give a new Laws to Messiah which would be somewhat different than Laws of Torah?
I think, in criticizing Scriptures one should be neutral. That means, not to take sides in belief or disbelief. Just as you would not want to make your conclusion dependent on belief on God and Christ, likewise you must not make you conclusion dependent on your disbelief in God or Christ or Holy Spirit. You just look at the story as whole, to determine the true view of the Bible.
But it seems that you are saying, let's criticize Bible assuming the Bible is not inspired by God there is no holy Spirit, there is no true God and no True Christ. This assumption is biased.
