New Testament

===Internal evidence===
Literary analysis of the New Testament texts themselves can be used to date many of the books of the New Testament to the mid-to-late first century. The earliest works of the New Testament are the letters of the [[Paul the Apostle|Apostle Paul]]. It can be determined that [[First Epistle to the Thessalonians|1 Thessalonians]] is likely the earliest of these letters, written around 52 AD.{{sfn|Brown|1997|pp=456–466}}
