Whether Catholic, Protestant, Orthodox, etc. this question is ideally for those well read in Biblical studies and ancient history.
We’ll begin with three brief questions:
How do you deal with the lack of original manuscripts, which leaves you only copies that cannot be compared to originals for accuracy?
How do you deal with the lack of an unbroken chain of transmission between the New Testament authors and today’s Christians? By lack, I mean an unbroken chain cannot be demonstrated, but merely assumed from deduction, based on the premises that “absence of evidence is not evidence of absence” and such.
How do you deal with the anonymity of the authors within the Gospel writings and the lack of detail, especially when compared to other ancient historical writings.
