On Philippians 2:6, "denounce" would be an improper interpretation.  The text speaks to Christ's humility in not asserting His equality with the Father even though He certainly did possess it.

If the Qur'an is an eternal manifestation of God's word, then why the need for abrogation?  (2:106 -- "Whatever a Verse (revelation) do We abrogate or cause to be forgotten, We bring a better one or similar to it. Know you not that Allah is able to do all things?")

If the Qur'an were addressing Medieval Platonic Christians in Surah 9, this should come as welcome news to the Coptic Christians in Egypt who are subdued dhimmis and other Christians throughout the Dar al-Islam who share the same fate and pay a jizyah.  Perhaps you could convince their Moslem overlords that they have erred in applying these texts outside the confines of the intended historical population.

Perhaps it could be recognized that the 270 million who have died by jihad perished in vain.  Why should peace be upon Muhammed?
