the process of the recognition and
collection began in the first centuries of the Christian church. Very
early on, some of the New Testament books were being recognized. Paul
considered Luke’s writings to be as authoritative as the Old Testament (1 Timothy 5:18; see also Deuteronomy 25:4 and Luke 10:7). Peter recognized Paul’s writings as Scripture (2 Peter 3:15-16). Some of the books of the New Testament were being circulated among the churches (Colossians 4:16; 1 Thessalonians 5:27).
Clement of Rome mentioned at least eight New Testament books (A.D. 95).
Ignatius of Antioch acknowledged about seven books (A.D. 115).
Polycarp, a disciple of John the apostle, acknowledged 15 books (A.D.
108). Later, Irenaeus mentioned 21 books (A.D. 185). Hippolytus
recognized 22 books (A.D. 170-235). The New Testament books receiving
the most controversy were Hebrews, James, 2 Peter, 2 John, and 3 John.
