The Roman Catholic Bible includes the Apocrypha which was written after the end of the Old Testament and before the beginning of the New Testament. This intertestamental period of 400 years was a time of great literary activity in spite of the fact there was no revelation from God. The Old Testament was translated into Greek in Alexandria, Egypt, during the period from 285 to 247 B.C. and was called the Septuagint. This translation was used by Paul, and our Lord apparently quoted from it.
The fourteen books of the Old Testament Apocrypha were written during this era and bear no marks of inspiration. There are two books classified as the pseudepigrapha: the Psalter of Solomon and the Book of Enoch. Although they bear the names of two men described in the Old Testament, there is no evidence that these men were the writers.
In some Protestant Bibles the Apocrypha is inserted in a separate block of literature between Old and New Testaments because the books shed some light on the 400-year lapse between the testaments. However, they are not regarded as part of the inspired Word of God for many reasons, one of which is that Jesus Christ never referred to them or quoted from them as He did the thirty-nine books of the Old Testament.
