Peter's Letter to Philip is part of the Christian Gnostic texts found in 1947 at Nag Hammadi. It probably dates from the late second or early third century. The letter's name comes from a beginning section where the apostle Peter says he sent the letter to the apostle Philip.
The letter is written in the form of a dialogue, a style common in Gnostic literature. The main part of the writing is a series of questions from the apostles to the risen Lord and his answers. These questions are used as a way to teach Gnostic beliefs about the world's structure, revealed by the "Divine Light." This "Light" is Christ, the heavenly redeemer.
