The canon of the New Testament is the set of books many modern Christians regard as divinely inspired and constituting the New Testament of the Christian Bible. For historical Christians, canonization was based on whether the material was from authors socially approximate to the apostles and not based solely on divine inspiration – however, many modern scholars recognize that the New Testament texts were not written by apostles. For most, it is an agreed-upon list of 27 books that includes the canonical Gospels, Acts, letters attributed to various apostles, and Revelation, though there are many textual variations. The books of the canon of the New Testament were written before 120 AD. Although the list of what books constituted the canon differed among the hundreds of churches in antiquity, according to ancient church historian Eusebius there was a consensus that the same 27 books constituting the canon today were the same 27 books generally recognized in the first century. For the Orthodox, the recognition of these writings as authoritative was formalized in the Second Council of Trullan of 692. The Catholic Church provided a conciliar definition of its biblical canon in 382 at the (local) Council of Rome (based upon the , of uncertain authorship) as well as at the Council of Trent of 1545, reaffirming the Canons of Florence of 1442 and North African Councils (Hippo and Carthage) of 393–419. For the Church of England, it was made dogmatic on the Thirty-Nine Articles of 1563; for Calvinism, on the Westminster Confession of Faith of 1647. From the end of the Apostolic Age, there has been a general consensus among the churches that there were 27 books in the New Testament. This is demonstrated conclusively in several ways. When Church Councils of the fourth century gave their lists of New Testament canons; they affirm that these were the same 27 books that were accepted as canonical from the time of their church fathers at the inception of their church, namely the first century bishops. For example the Council of Carthage in 397 CE stated that the church received from its "fathers" the books which should be received as scripture. Evidence corroborates the claims of the fourth century church councils that their canonical list are the same 27 books that the church received from the earliest bishops. 25 of the 27 New Testament books received as canonical by councils in the 4th
