A man who has enough foolishness to defect from benedictine monastery to the reformed anglican heterodox heresy can hardly have have the ability to pass on a sacred art tradition “not made by human hands”
I strongly recommend avoiding Peter Pearson. The only people I know of that he teaches have been more superficial western catholics and protestants with very little knowledge, study or exposure to art history or any other cultural history, especially church history. Though a few of them have do start classes of their own (one teaches at a local catholic high school) and expose the sacred art to other westerners they are still missing something authentic which holds them back from every having anything on the walls of an Eastern Church.
From my own experience when i talked to Peter Pearson he showed no interest in reviving or promoting the iconography of the western church and its own particular idiosyncratic culture but rather saw it as a poorly conceived mostly barbarian corruption better off forgetting ever existed.
If one is not careful with Peter Pearsons influence soon enough they’ll be painting this in anglican churches as they dance along with Mr Pearsons brethren into cacodoxy.
