Hi JesusFan
You asked..........
“Does ItREALLY Matter IF Authors Assigned To Books Wrote the Books In Bible?”
That is a big
“YES”.
Because every book in the Bible is of the same authorship;
And the men that God chose to use to pin His Word, were “pointed out” by God......
Hebrews 2:3-4
V.3 How shall we escape, if we neglect so great salvation; which at the first began to be spoken by the Lord, and was confirmed unto us by them that heard [him];
V.4 God also bearing [them] witness, both with signs and wonders, and with divers miracles, and gifts of the Holy Ghost, according to his own will?
This is why they performed miracles.

Another reason why we know this is important, is because for centuries, those who hated God and His Word, have attacked the authorship of Bible Books, in an attempt to cast doubt on the Bible’s legitimacy.
For instance, if anyone can convince us that Moses didn’t write the first five books of the Bible by Verbal Inspiration, than they will have successfully put a doubt in our mind, of the truths that are found their.
