What Books of the Bible Did Peter Write?
Saint Peter, or Simon Peter, is traditionally credited with writing two books of the New Testament. They are I Peter and II Peter. These books are epistles, or letters, written as instructional texts for the laity of the early Christian church.
Most biblical scholars agree that Peter was likely not the actual author of the texts and that the true credit of authorship lies elsewhere. The unlikelihood of Peter's authorship is assumed because the writer(s) of both books had an understanding of rhetoric and the Greek language, which Peter likely did not. Also, the epistles were written after Peter's death.
