I notice that whenever Fundamentalist Protestants believe something the Church fathers believed about the "old testament," the first eleven chapters of Genesis, or the Creation, the belief of the fathers is dismissed as "they were men of their time." But when the Church fathers believed something that Fundamentalist Protestants simply cannot stretch their minds around or believe in good conscience that Catholic apologists suddenly treat those opinions as infallible and non-negotiable.
Hence real presence is "absolutely essential," and six day young earth creationism is almost banned.
zionist Conspirator:
I think you are mistating your case. One can believe in literal 6 day of creation or one can choose not too, as Caatholic as that ultimately is a scientific question not a theological one. The theological issue Whether the Eucharist is truly the sacrament of Christ’s body of Blood and thus partaking of the Eucharist is nothing short of communion with God, that is a theological position that the Fathers were consistent on.
