Among Petrines, the Quran is recognisable as a decisive manifestation of the othrwise ethereal Petrine Lectionary in a strike against the spread of Mandaism in particular but also various other dark-age dogmas among Arabic pagans. Similarly, many of the early "Gnostic" documents, like the coptic letter of Peter to Philip, could be better understood as attempts written in Gnostic terms to bring the fore-runners of the Mandaeans back to the straight path.
The Abbeys represent the Petrine Magisterium, while the Noble houses with their heraldry and maintaining the chivalric Nomos represent the descendants of the 36 pairs of Nizariun sent out to the 70 nations of the world promoting the doctrine of accommodation (which was eventually adopted in the 7th century by Pope Gregory the Great) and appointed bishops from these families over the Abbeys in their realms. Only the House of Imran wearing Ephods as crowns were ever regarded as the rightful Koenigs among them wearing Ephods as crowns.
