please note Kelly, that you have not been given the right information. it’s not “some Catholics” who believe in the Real presence of Christ in the Eucharist — it’s all Catholics and all Orthodox and all Lutherans and all Copts and many Anglicans and Methodists.
Any Christian religion that observes this ritual is doing it symbolically and forthe same reason as far as i can tell. And the word “some” is just force of habit. Im sure all Catholics believe the same rxact things.
