Stained glass windows, statues, candles for the dead and the use of incense smokers(censers) in some Catholic congregations...yes Catholic churches have used their own special effects over the years as have Episcopalians and many others...(Fried Chicken dinners for southern baptists, LOL. Don’t know if all the good food makes one more spiritual but it makes one comfortably sleepy).
Not saying what’s right or wrong but let us not be smugly self righteous about one’s choice of churches. They all have their own “special effects” even if a particular church strives for simplicity of worship.
Yet enjoying a communal meal was one of the earliest practices of the Christian church - as recorded in both scripture and historical sources.
