The Church brings people home to Orthodoxy throughout the year. At times these people are "famous." There is a rather unwholesome spectacle often made of these moments that (if you'll forgive a personal opinion) needs to be tamped down a bit. For one, God delights in every soul brought to Him regardless of what they do for a living or what their Nielsen rating is. TV stars, radio personalities, movie actors, garbage truck drivers, Sleep Master mattress salesmen, et al. are all cause for celebration but they are also honestly just on the start of a long process of ascetic struggle. What they need is prayers, not plaudits.
Honestly, as someone who has been an avid listener to Ancient Faith Radio podcasts, Orthodox Youtube series, and other such media I can attest to how we seem to give near adulation to our clergy only to see them flame out spectacularly in a way that is destructive to the people who have elevated these personalities to unrealistic heights. We aren't a church of televangelists and for good reason.
Can we acknowledge the joy we feel at someone we know (whether personally or as a media personality) joining the Body of Christ? By all means. But we should do so understanding that Jesus commands nothing short of complete conversion and this is not an easy process nor one that everyone who starts to "run the race" finishes with the "imperishable crown." Let's take the fangirling down a notch for their sakes and our own alike.
