The Bible is inspired by God, and written by men in the power of the Holy Spirit. Each of the gospel writers brought their own experience and thoughts to his gospel. That is why Matthew pictures Christ as the son of man; Mark as the servant of God; Luke as the King; and John focuses on Christ as God.
Now, if you want to critique the Bible why not focus on doctrine and what it teaches, not the differing perspectives of 4 different men? The only thing you are showing is you have not really studied the Bible and are attempting to nit pick what you see as discrepancies and I see as reliable records of witnesses, and since no two human witnesses will document identical scenes, this validates (in my opinion) Biblical truth. I would be more likely to challenge the Bible is the four gospels were in total agreement done to the last stroke of the pen, since that would indicate a collaboration not divine inspiration.
