I have a similar fear, but for other reasons. I am horrified how, in the Catholic Church, the faithful - Priests and laity - have fundamentally transformed the cult of the Saints; people only want media personalities canonized now, rather than actual Saints or relatable individuals like you and me; and people want them canonized as quickly as possible, without any research or hesitation into their lives that may reveal some grimmer details, because their media presence is sufficient per se for their Sainthood.
Gone is the day where people like St. Aloysius were canonized, a Roman Catholic Saint, a rich young man who gave up all his possessions to enter into religious life, and died caring for Italians who were suffering from a nasty plague - now is the day where people want Mother Teresa's, Mother Angelica's, Fulton Sheen's canonized. Media personalities.
Catholics are banging their fist against a table to get Fulton Sheen canonized, just because he held a television program and taught orthodox things during that television program, as well as providing foundational education in classical Christian education like logic, grammar, philosophy, etc.
However, the Diocese of New York and the Vatican have been very hesitant and wanting to delay the canonization; some think that it's an outward maliciousness to orthodoxy. Maybe it is, but if you look into his life passed the media personality figure, you'll find that he had tons of failures as a Bishop and there are allegations of complicity with sexual abuse. He allegedly called a woman a harlot after he caught a priest sexually assaulting her.
Did Fulton Sheen witness and cover up the sexual assault of a child?
That's not to mention he became pretty Liberal in his later life; one just has to watch him on William Buckley's show. He said that the Catholic Church was nothing more than a kingdom stuck in a high tower closed off to the world, and that needed to change with an opening up via Vatican II, and almost suggests that the Church was wrong with the practice of excommunication.
Yet organizations like Church Militant will continue to pump out that the Vatican and New York Diocese is Satan incarnate for refusing to canonize Fulton Sheen, part of this systemic conspiracy to legitimize same-sex marriage. How dare they investigate these allegations and these problems?!
It's not completely gone per se - John Henry Newman's canonization is evidence of that. But as soon as famous historical figures run out, I think that the only way forward for Catholics will be, unfortunately, media personalities.
Orthodoxy still has an authentic cult of the Saints, and it would be horrendous if the same process happened to it. Saint Paisios certainly was not popular because of his popularity in the media.
