Many are not knowledgeable because they are not in the least bit interested in reading , in depth, the history of Jesus and the Church. It is all so detailed with so many names and dates that they are either overwhelmed by it all or lose interest. I like reading church history, or what I refer to as it’s history as in:
There are tens of thousands of manuscripts from the New Testament, in part or in whole, dating from the second century A.D. to the late fifteenth century, when the printing press was invented. These manuscripts have been found in Egypt, Palestine, Syria, Turkey, Greece, and Italy, making collusion unlikely. The oldest manuscript, the John Rylands manuscript, has been dated to 125 A.D. and was found in Egypt, some distance from where the New Testament was originally composed in Asia Minor. Many early Christian papyri, discovered in 1935, have been dated to 150 A.D., and include the four gospels. The Papyrus Bodmer II, discovered in 1956, has been dated to 200 A.D., and contains 14 chapters and portions of the last seven chapters of the gospel of John. The Chester Beatty biblical papyri, discovered in 1931, has been dated to 200–250 A.D. and contains the Gospels, Acts, Paul’s Epistles, and Revelation.
The number of manuscripts is extensive compared to other ancient historical writings, such as Caesar’s “Gallic Wars” (10 Greek manuscripts, the earliest 950 years after the original), the “Annals” of Tacitus (2 manuscripts, the earliest 950 years after the original), Livy (20 manuscripts, the earliest 350 years after the original), and Plato (7 manuscripts).
