The early church fathers agreed that certain books were considered infallible and inerrant. While some held in high regards the writings in the Apocrypha, it was their consensus that writings didn’t measure up to the same standards as what was considered to be the scriptures. That is how the early Bible was put together.
One thousand years later, the Council of Trent decided certain books of the Apocrypha should be included. That is the difference between the Protestants and Catholic versions of the Bible.
The preponderance of the evidence seems to support the above summary. It is clear from the evidence presented the ECFs saw a clear distinction between what was scripture for doctrine and what was not. At Trent, there was a NEED for the Roman bishop to make the apocrypha equal with the historic canon. So while folks are reliving the wars of the 16th century, let's hear the Words of Jesus Christ:
Luke 24:
44 And he said to them, “These are my words that I spoke to you while I was still with you, that everything that is written about me in the law of Moses and the prophets and psalms must be fulfilled.” 45 Then he opened their minds to understand the scriptures, 46 and said to them, “Thus it is written that the Christ would suffer and would rise from the dead on the third day, 47 and repentance and the forgiveness of sins would be proclaimed in his name to all the nations, beginning from Jerusalem.
