The Basilidians believed in a very different Gospel to that of orthodox Christians. Hippolytus summed up the Basilidians' Gospel by saying: "According to them the Gospel is the knowledge of things above the world, which knowledge the Great Archon understood not: when then it was shewn to him that there exists the Holy Spirit, and the [three parts of the seed-mass] and a God Who is the author of all these things, even the not-being One, he rejoiced at what was told him, and was exceeding glad: this is according to them the Gospel."
