Biblical Prayer Contradictions

[Longhorn]

If I point to OT vs NT contradictions, you'll say Jesus came to abolish the law, and if I point to verses that contradict gods omniscience, you can always stretch your interpretation as metaphorical; let's instead focus on the factual contradictions between the gospels alone then

I've picked a few that I consider most clearly contradictory and could not otherwise be assigned to simple error:

15) Matthew 2:15, 19 & 21-23 The infant Christ was taken into Egypt. Luke 2:22 & 39 The infant Christ was NOT taken to Egypt.

18) What was the nationality of the woman who besought Jesus? Matthew 15:22 "And behold, a woman of Canaan came out of the same coasts, and cried unto him, Have mercy on me, 0 Lord, thou son of David; my daughter is grievously vexed with a devil." Mark 7:26 "The woman was a Greek, a Syrophenician by nation, and she besought him that he would cast forth the devil out of her daughter."

21) Can one pray in public? (Matthew 6:5-6) Jesus condemned public prayer. (1 Timothy 2:8) Paul encouraged public prayer.

There are many many more, but let's for the sake of brevity and convenience focus on those three

What do you make of them?
