Yes, it seems so.If this is the case, American EO's certainly deviate from the typical in Europe. I've never seen an EO or RCC classroom either.
After Vatican II the RCC has moved towards English mass, which traditional Catholics seem to disapprove of.
So many Protestant worship services are really just new age encouragement with really loud music.
But I'm still looking...the pandemic has put a damper on congregations....
So I tried the Orthodox local churches. I plan to visit the Russian ones too.
I have visited RCC services and they are not in Latin at the one in Piedmont Oklahoma and Midwest City OK. But the incense choked me! I think the Orthodox churches here in the USA are closer to what is intended.
