The Catholic canon comprises 46 books, and the canons of the Eastern Orthodox and Oriental Orthodox Churches comprise up to 51 books and the most common Protestant canon comprises 39 books.
What is The Bible?The Bible is a canonical collection of texts sacred in Judaism and Christianity. There is no single "Bible" and many Bibles with varying contents exist. The term Bible is shared between Judaism and Christianity, although the contents of each of their collections of canonical texts is not the same.
Different religious groups include different books within their Biblical canons, in different orders, and sometimes divide or combine books, or incorporate additional material into canonical books.
The Hebrew Bible, or Tanakh, contains 24 books. Christian Bibles range from the 66 books of the Protestant canon to the 81 books of the Ethiopian Orthodox Church canon.

The Catholic Church and Eastern Christian churches also hold certain deuterocanonical books and passages to be part of the Old Testament canon.
The second part is the New Testament, containing 27 books: the 4 Canonical gospels, Acts of the Apostles, 21 Epistles or didactic letters, and the Book of Revelation.
What is Apostasy?Apostasy (Greek: apostasia, 'a defection or revolt') is the formal disaffiliation from, or abandonment or renunciation of a religion by a person. It can also be defined within the broader context of embracing an opinion contrary to one's previous beliefs. One who undertakes apostasy is known as an apostate. The term apostasy is used by sociologists to mean renunciation and criticism of, or opposition to, a person's former religion, in a technical sense and without pejorative connotation.
