How do the Sola Scrptura folks react to the Dead Sea Scrolls and other more recent discoveries of ancient Biblical texts not among those canonized by Martin Luther?

Even Jesus questioned how the Messiah was David's son.

If you study, you will find passages in the Orthodox Bible, not in the Catholic.

However, if one is using the Bible as a premise and traditions, how does one evaluate discrepancies between the two, as traditions are interpretations of Bible passages as their claim for validation.

Why do most atheists in debates with theists take Bible verses out of context much of the time? Are they lying maliciously or do they not understand theology enough to understand the meaning?

In response to A2A:

Nuda Scriptira is scripture alone. Sola Scriptura is writings authority over traditions and does not imply Biblical inerrancy (see above in regards to Jesus, and genealogy to David).

Since the Bible is a collection of writings (literally what biblia means), you will even find that while Matthew and Luke have genealogies, Paul wrote to Titus and Timothy not to pursue foolish genealogies.

Do interviewers discriminate against a candidate if he or she is overweight (assuming physical fitness is NOT part of the job requirements)?

Actually, Luther was influenced by the books of the Masoretic Tanakh and did, originally, include the Apocrypha.

The influence of the Christian Old Testament was the Septuagint, which predates Jesus. Luther, also maintained the Septuagint philosophy of law, history, poetry and prophets, in ordering, while the Tanakh followed Torah, prophets (Nevi'im) and writings (Ketuvim).

The New Testament was established as part of creating a universal (catholic) interpretation for all Christians.

Just as there are a few discrepancies between the Masoretic and Samaritan Torahs.
