What is Gospel of Pistis Sophia and what does it include?

Question

Does it include Gospel of Philip and Gospel of Mary Magdaline?

Answer 1

The "Pistis Sophia" is an important Gnostic text, its title means "the Faith of Sophia", or "Faith in Wisdom", or maybe "Wisdom of Faith"

It is its own text and not a "gospel", nor does it include gospels in it, but it is often found together, possibly in the same volume, with the gnostic gospels you mention, because they belong to the same branch of christian mysticism.
