Answer:
The sacred text of Christianity is the Bible which is composed of the Old Testament and the New Testament.
Explanation:
The Christian Bibles are constituted by Hebrew, Aramaic and Greek writings, which have been taken from the Greek Bible, called Septuagint, and from the Hebrew-Aramaic Tanakh, and then regrouped under the name of Old Testament. To these has been added a third series of Greek Christian writings grouped under the name of the New Testament.
