Okay, so do you therefore accept the Quran as a historical record of Jesus/ Isa also?
I wouldn't as a historian and as a believer I wouldn't necessarily take it literally, although I do accept accept its Christology.
One of my favorite books is Miracles and Metaphors which is a series of essays written by the 19th century Baha'i scholar Mirza Abu'l-Fadl. He outlines the following principles which I believe is essential to understanding the proper relationship between religion and science:
"The Prophet Muhammad said, "We, the concourse of Prophets, were
commanded to address the people according to the capacity of their
minds," and, likewise, "Speak to the people of that with which they
are familiar. Do you wish God and His Messenger to be accused of
lying?" Thus was it related by the learned judge Muhammad ibn Ahmad
Rushd al-Andalusí [Averroes] "It is well known that the Prophets and
Manifestations of the Cause of God were sent to guide the nations, to
refine their characters, and to bring the people nearer to their
Source and Ultimate Goal. They were not sent as historians,
astronomers, philosophers, or natural scientists the Prophets indulged
the people in regard to their historical notions, folk stories, and
scientific principles and spoke to them according to these. They
conversed with them as was appropriate to their audience and hid
realities behind the curtain of allusion." (p. 39)"It has, then, been
established that the historian cannot depend for historical knowledge
upon the outward meanings of Qur'anic verses and that Noah and his
like are not mentioned in the rest of the ancient histories." (p. 40)
I think it'a an advantage because they offer multiple perspectives.
There are some advantages to this, but since none of the Gospels can with any certainty be traced to a particular author all it gives is the various perspectives of the early church, whereas the Qur'an can be directly associated with Muhammad.
When you consider, that the NT gospels writers had no idea at the time that what they were recording was eventually going to develop in to a major religion, then the idea of any collusion or agenda other than simply recording the facts as they saw them is very implausible
Oh, each one clearly had an agenda and any many cases they borrow from one another and probably from an additional source which scholars refer to as Q.
Who did he meet on the road to Damascus (Acts 9:5)?
I am willing to concede that Paul's is the only eyewitness we have in the Bible to having seen the Resurrected Jesus, but I would argue that his description is the
least physical.
But this fragment doesn't date back to when Muhammad was alive, which was your original point?
The parchment dates from 568 and 645. The Prophet dies in 632, well within that period.
