Hi onlyhis,
Friend, it's not a new debate. It has been debated since the canon was first established. I always point to Jesus' claim that God would preserve His word. If God wanted these additional writings in there, then they would have been in there all along. I'm funny that way. I find that the God I serve and the God that I read of in the Scriptures is powerful enough to do the things that He wills to be done among the hearts and minds of men, as regards the working out of His plan.
The Scriptures even tell us that the very thoughts and ideas written about in the Scriptures didn't come from the minds of the men who wrote the words, but rather as they were led along by the Holy Spirit. If the Holy Spirit of God can cause godly men to write exactly what He wants written, then I surely have no problem whatsoever in seeing that that same God, by that same Spirit then continues, to this day, to see to it that the 'book', what we call the bible, is also, by the leading of His Holy Spirit working in the hearts and minds of the men who established the canon to deliver to us exactly what God wants delivered.
In other words and from the flip side of the coin. If God wanted the extrabiblical writings of the Apocrypha included in His book. They would be there!!!! As it is today, we have these writings available to us just as we have Homer's Illiad and Odyssey, William Shakespeare's writings, Josephus' writings and they can all be weighed for their truth against the writing that God has delivered to us and protected and preserved so that no man may have excuse.
God bless you.
In Christ, Ted
