Im not kidding.
They declared Adam and Eve to be "metaphors" a long time ago. Would this be any different?
Nope, not a bit. Incrementalism in action.
Excellent point.
“They declared Adam and Eve to be “metaphors” a long time ago.”
Incorrect.
The Catechism of the Catholic Church
# 375 The Church, interpreting the symbolism of biblical language in an authentic way, in the light of the New Testament and Tradition, teaches that our first parents, Adam and Eve, were constituted in an original “state of holiness and justice”. This grace of original holiness was “to share in. . . divine life”.
# 390 The account of the fall in Genesis 3 uses figurative language, but affirms a primeval event, a deed that took place at the beginning of the history of man. Revelation gives us the certainty of faith that the whole of human history is marked by the original fault freely committed by our first parents.
