Since the Catholic Church isn’t a denomination, they are excluded. All of the Protestant denominations have something wrong with them tho. The one thing they share in common is they don’t believe the bread and wine, when consecrated, become the true Body and Blood of Christ. They are merely symbols of remembrance to Protestants.
Most of the non-Catholic Christian denominations do not believe that the Eucharist is the Real Presence. They believe it is symbolic --the bread is just bread, the wine (or juice) is just wine or juice.
To me, that is probably the most tragic wrong that has come about through "protesting’ authentic Catholic/Christian beliefs.
Since the Catholic Church is not a denomination but is the Church founded by Jesus Christ, if a teaching wasn’t received from us, then it is in error.
So, yes, every protestant denomination is wrong on some points. I hear a lot of protestants say the same thing. Thing is, without a Church with the authority to teach, there’s no real way to know the error of one’s denomination.
