The sacred text of Christianity is the Christian Bible, which includes the Hebrew scriptures, the gospels and the writings of early church figures like the Apostle Paul. Some Christian traditions also include the Apocrypha.
The Hebrew scriptures, which Christians call the Old Testament, are versions of those used by the Jewish people, though the order of these books is different in the Christian Bible than in the Jewish Bible. The four gospels tell the life of Jesus Christ, and the writings of the early church figures like Paul and Peter detail theological matters in a more comprehensive, analytical way and instruct the growing religion on church governance issues. The apocryphal books are not accepted by every sect of Christianity, and some Bibles exclude them altogether.
