The New Testament is a collection of 27 books, all written in Greek within the first century A.D. Twenty-three of these books were written by the Apostles of Jesus Christ, two were written by Dr. Luke a Christian medical doctor who traveled with the Apostle Paul, and two books were written by James the brother of Jesus, a leader at the church in Jerusalem and who spent time with the Apostle Paul. These books were compiled by the Christian church in a selection process between the second and fourth centuries A.D. and determined to be the inspired words of God. These books were then finalized to create a canon of Scriptures, which we now call the New Testament of the Bible – a collection of books – by the Christian church in the sixteenth century. This completed the Christian Bible with a final collection of 66 books made up of both the Old and New Testaments.
It should be noted that the Roman Catholic and Eastern Churches have added some additional books to their canon, known as the Apocrypha books. The Apocrypha books make no claims of being inspired by God and were written by unknown Jewish authors between 420 B.C. and 27 A.D., the period between the Old and New Testaments.
