@Senneferet I have found some information from http://factsanddetails.com/world/cat56/sub403/entry-6113.html
You spoke about a pastoral role for a modern P/Less. One section of this website talks about lay magicians and their roles.
I don’t know much about the source mind you. Bit mysterious as to where the information has come from but there certainly seems to be a lot of it! Going from what @kev has said about magicians in the past, this seems to correct:
*lay magicians supplied a commoners understanding of Egyptian religion. Through the use of magic and their connection to the gods, lay magicians provided a service to their community, usually consisting of counseling, magical arts, healing, and ceremony. Lay magicians who served within this last and final caste of the Egyptian priesthood belonged to a large temple known simply as “The House of Life”. Laymen would come to “The House of Life” to meet with a magician, priest or priestess to have their dreams interpreted, to supply magical spells and charms, to be healed and to counteract malevolent magic, and to supply incantations of various types. Though the House of Life provided it’s Laymen with many prescriptive cures for common ills, it was largely shrouded in mystery in ancient times. In fact, the library of The House of Life was shrouded in great secrecy, as it contained many sacred rites, books, and secrets of the temple itself which were thought could harm the pharaoh, the priests, and all of Egypt itself. Though the magicians of The House of Life, were seen as another step from the ceremonial duties of the priests, they were by no means less important, and as is evidenced by the presence of many magical wands, papyri text, and other archeological evidence, The House of Life took on a role direly important to the way of life of Ancient Egyptians." +*
The more I read, the more I think there were a lot of different types of P/Pess ranging from full-time to part-time, some directly attending open statues and some not, some working out in the community, some not.
I think in Kemetcism today, all practitioners are encouraged to research, learn and serve the gods in a personal way. Most of society in the UK are literate with access to all sorts of resources and education. More so than the common AE.
This actually reminds me of how work has changed over generations. There used to be designated roles, but now with lack of budgets and better technology, we are expected to have a whole range of skills and take on different aspects of work. One job title now means using a wide range of skills.
Could perhaps argue that Kemeticism has developed in a way where all practitioners are what the ancients would call P/Pesses? Just depends on what form the gods are calling you to?
