I wish you would take the trouble to read it. There are posts which attack our teaching and even when more is said about it, the posts persist as though we had posted nothing. It seems unfair to mock something or even to draw conclusions about it if one won't do the work to find out what the thing is.
Here's the place to start:
The Holy Eucharist
GENERAL: The sacrament itself (73). The matter of this sacrament: its species (74), the transubstantiation (75), the real presence (76) and the accidents (77) of bread and wine. The form (78) and effects (79) of this sacrament. The recipient in general (80) and at its institution (81). The minister (82) and the rite (83) of this sacrament.
People who won't read this will have trouble making a coherent argument against it, because they are usually arguing against what somebody else who read an article by somebody else about a book by somebody else about what you can read for yourself right here.
I did read it.
