So, lemme ask ya: Were YOU there when any of those mss. were written ? Can you tell us who wrote them, where & when, and what sources were used ? If not, you have no right to be a mss. critic. And, can you prove that GOD didn't preserve any of these mss ?
I TRUST GOD to have passed His word down to us in the mss. HE preserved & caused to be translated into over 2400 languages & dialects so far. Nowhere is God limited to one manuscript or translation. Remember, HE made all languages & dialects, and HE sees to it that His word is available in them.
