Every Catholic that i know knows it. It’s the main difference between communion for Catholics and other Christian denominations.
The Lutheran Church Missouri Synod parish I sometimes go to takes the Real Presence of the Eucharist very seriously...
...stating exactly that it's the Body and Blood of Jesus Christ every single time someone takes Communion at its alter rail.
No "Eucharistic Ministers", either.
If I remember right the classes were taught by a deacon so the information provided should have been correct.
My conclusion is that the Eucharist was not covered in either class. Which would seem odd to me. If you are getting back to basics that would be a point I would cover.
Maybe it is just okay these days to question the authority of Church teaching. After all it seems to be okay for Priest, Bishops and Cardinals to do so.
there are some protestant denominations and a number of nondenominationals that believe in the Real presence of Christ in His supper minus some of the extra biblical stuff Rome throws in
