“You never answered his question. When did the Church have access to the New Testament in the form that we have it today?”
Actually, I did answer his question.
No, you didn’t.
One, you never specified a time.
Two, you spoke of books, individual, not of the bible as a whole, which is what his question asked.
So when did the bible first appear in the form in which we are familiar with today?
Many are deceived because they do not have the entire Bible. Read first and second Maccabbees.
