1) The oldest NT bookjs you refer to are NOT examples of the Majority Text. How can you cite them as evidence of reliability of transmisison and then claim that the Majority Text is the original ?
2) Citing both the Dead Sea Scrolls and the Masoretic Text is a similar problem. THe DSS includes texts which more closely match the Septuagint texts - but written in Hebrew. You can't claim that both the DSS and the Masoretic texts both represent an inerrant original when there are scrolls in the DSS that are from a different text tradition - and one that may be as old or olfer than the Masoretic text.l
