Why should Fr Pfeiffer, Bp Williamson, Bp Zendejas, Fr Chazal or priests of the SSPX worry about an Orthodox bishop when the Orthodox split from the Catholic church a thousand years ago?
They shouldn't.
Problem is fr. Pfeiffer worked with this charlatan in 2015, supposedly split with him, brought him back in 2018, had "fr"poisson conditionally ordained by moran, and then supposedly split with him again.
Fr. Pfeiffer is without a bishop (as is fr. Hewko) and he has a "seminary" and "convent" without a bishop. These are all violations of canon law. Fr. Pfeiffer knows it and is scrambling to find a bishop he can keep in his pocket, who will do his bidding. Moran was the best he could find, willing to work with Mr. Hernandez (aka pablo, "el diablo, "lay exorcist", etc) and himself.
A charlatan posing as a catholic bishop should be avoided at all costs.
Although, moran might be better than the rumors i hear about fr. Pfeiffer's association with Ryan St Anne Scott
