Scripture
See also: Development of the New Testament canonIrenaeus pointed to Scripture as a proof of orthodox Christianity against heresies, classifying as Scripture not only the Old Testament but most of the books now known as the New Testament, while excluding many works, a large number by Gnostics, that flourished in the 2nd century and claimed scriptural authority.
Before Irenaeus, Christians differed as to which gospel they preferred. The Christians of Asia Minor preferred the Gospel of John. The Gospel of Matthew was the most popular overall. Irenaeus asserted that four Gospels, Matthew, Mark, Luke, and John, were canonical scripture. Thus Irenaeus provides the earliest witness to the assertion of the four canonical Gospels, possibly in reaction to Marcion's edited version of the Gospel of Luke, which Marcion asserted was the one and only true gospel.
Based on the arguments Irenaeus made in support of only four authentic gospels, some interpreters deduce that the fourfold Gospel must have still been a novelty in Irenaeus' time. Against Heresies 3.11.7 acknowledges that many heterodox Christians use only one gospel while 3.11.9 acknowledges that some use more than four. The success of Tatian's Diatessaron in about the same time period is "...a powerful indication that the fourfold Gospel contemporaneously sponsored by Irenaeus was not broadly, let alone universally, recognized."
Irenaeus is also our earliest attestation that the Gospel of John was written by John the apostle, and that the Gospel of Luke was written by Luke, the companion of Paul.
The apologist and ascetic Tatian had previously harmonized the four gospels into a single narrative, the Diatesseron (c 150-160).
Scholars contend that Irenaeus quotes from 21 of the 27 New Testament Texts:
Matthew (Book 3, Chapter 16)
Mark (Book 3, Chapter 10)
Luke (Book 3, Chapter 14)
John (Book 3, Chapter 11)
Acts of the Apostles (Book 3, Chapter 14)
Romans (Book 3, Chapter 16)
1 Corinthians (Book 1, Chapter 3)
2 Corinthians (Book 3, Chapter 7)
Galatians (Book 3, Chapter 22)
Ephesians (Book 5, Chapter 2)
Philippians (Book 4, Chapter 18)
Colossians (Book 1, Chapter 3)
1 Thessalonians (Book 5, Chapter 6)
2 Thessalonians (Book 5, Chapter 25)
1 Timothy (Book 1, Preface)
2 Timothy (Book 3, Chapter 14)
Titus (Book 3, Chapter 3)
1 Peter (Book 4, Chapter 9)
1 John (Book 3, Chapter 16)
2 John (Book 1, Chapter 16)
Revelation to John (Book 4, Chapter 20)
He may refer to Hebrews (Book 2, Chapter 30) and James (Book 4, Chapter 16) and maybe even 2 Peter (Book 5, Chapter 28) but does not cite Philemon, 3 John or Jude.

Famous quotes containing the word scripture:
“To say that God is an incorporeal substance, is to say in effect there is no God at all. What alleges he against it, but the School-divinity which I have already answered? Scripture he can bring none, because the word incorporeal is not found in Scripture.”
—Thomas Hobbes (1579–1688)
“Openmindedness should not be fostered because, as Scripture teaches, Truth is great and will prevail, nor because, as Milton suggests, Truth will always win in a free and open encounter. It should be fostered for its own sake.”
—Richard Rorty (b. 1931)
“All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: that the man of God may be perfect, thoroughly furnished unto all good works.”
—Bible: New Testament 2 Timothy 3:16-17.
