I too was raised in the cofC and left after HS graduation. The congregation I was in, and all the others I visited had two short extempore prayers at the “Lord’s Table” one for the matzo crackers and the other for the grape juice, and they always used words like reminder, emblem, symbol.
But being fair to this denomination there is really no official doctrine and the individual may beleive what they wish about the Lord’s Supper. I am sure their are some cofCers that do beleive in the real presence, but I think they would form a small minorty,and since they have no clergy they would have no way to confect the Real Presence.
The only thing cofC preachers can do that other members can’t do is marry and that is only for legal reasons.
I remember once a small boy responded to the invitation to be baptised and his Dad a high school choir teacher jumped up to dunk his son.
They claim the Lord’s Supper is very important to them, but is just one of the prescribed acts of worship and they get it over very quickly to get to the all important sermon and invitation which is the real highlight of the sevice.
