The New Testament is a collection of Christian texts originally written in the Koine Greek language, at different times by various different authors. While the Old Testament canon varies somewhat between different Christian denominations, the 27-book canon of the New Testament has been almost universally recognized within Christianity since at least Late Antiquity. Thus, in almost all Christian traditions today, the New Testament consists of 27 books:

• 4 Canonical Gospels (Matthew, Mark, Luke, and John)
• 1 Acts of the Apostles
• 14 Epistles of Paul
• 7 General Epistles, and
• 1 Book of Revelation.
