You should look at the picture to appreciate the volume of writing produced by these people.

 There are 22,896 pages altogether.  It is said that these works contain 86,000 Bible quotations and that all but 11  verses are quoted in there.   If every New Testament manuscript were destroyed for some reason, we would still know what the New Testament contained.

Not only are these volumes important for preserving the text of the Bible, but also for what the early church believed and what it considered heresy, because they would teach against it.  I take note of the fact that Muslims do are not justifying the Quran's view of what happened with Jesus using the Early Church Fathers.

Question for Muslims: How did we get from what the Quran says happened to what is recorded in the Gospels, their translations, the early church fathers and non-Christian writings of the time.
