The Gospel of Philip is a non-canonical Gnostic Gospel dated to around the 3rd century but lost in medieval times until rediscovered by accident, buried with other texts near Nag Hammadi in Egypt, in 1945.
The Gospel is not accepted as canonical by the Christian church. Although it may have some relationship to the beliefs expressed in the Gospel of Thomas, scholars are divided as to whether it should be read as a single discourse or as a collection of otherwise unrelated Valentinian sayings. Sacraments, in particular the sacrament of marriage, are a major theme. As in other texts often associated with what has been referred to as "Gnosticism," such as the Gospel of Thomas and Gospel of Mary, the Gospel of Philip defends a tradition that gives Mary Magdalene a special relationship and insight into Jesus' teaching. The text contains fifteen sayings of Jesus. Seven of these sayings are also found in the canonical gospels, and two are closely related to sayings in the Gospel of Thomas.
The gospel's title appears at the end of the Coptic manuscript in a colophon; the only connection with Philip the Apostle within the text is that he is the only apostle mentioned (at 73,8). The text proper makes no claim to be from Philip, though the four New Testament gospels make no explicit internal claim of authorship either. Most scholars hold a 3rd-century date of composition.
A single manuscript of the Gospel of Philip, in Coptic (CG II), was found in the Nag Hammadi library, a cache of documents that was secreted in a jar and buried in the Egyptian desert at the end of the 4th century. The text was bound in the same codex that contained the better-known Gospel of Thomas.
From the mix of aphorisms, parables, brief polemics, narrative dialogue, biblical exegesis (especially of Genesis), and dogmatic propositions, Wesley W. Isenberg, the editor and translator of the text, has attributed seventeen sayings (logia) to Jesus, nine of which characterizes as citations and interpretations of those found in the canonical gospels The new sayings, "identified by the formula introducing them ('he said', 'the Lord said', or 'the Saviour said') are brief and enigmatic and are best interpreted from a gnostic perspective.
