(1) Please don’t misrepresent me: I never referred to the Genesis story as a fable.
(2) Catholic (and non-Catholic) theology employs symbol, story, and metaphor. The Hebrew story of the forbidden fruit is rife with symbolic and metaphorical language. Christians took this Hebrew story and developed from it a theology of “original sin” and the “cleansing” of that “original sin” by the salvific death of Jesus, the Christ. This language is still theologically serciveable, even after modern genetics has conclusively demonstrated that the human species cannot have dropped much below 3,000 breeding pairs without suffering an irreversible genetic bottleneck.
(3) When humans evolved into consciousness, they became aware that not all is right with the world, that there is greed and selfishness, murder, rape, pillage, arson, etc. In other words, they realized that the human condition is one of brokenness, of failed relationships (to use Pope Benedict’s language). All spiritual traditions have accounted mythically for why this is so, the Greeks employing the symbol of Pandora and her box, and the Hebrews the symbol of the forbidden fruit and of “Adam’s” and “Eve’s” disobedience.
(4) The sacraments are living signs of spiritual realities. Baptism symbolically uses water as a sign of the “cleansing” of the “original stain” that humans have always recognized. Baptize represents, or makes present the reality of God’s saving power by initiating the candidate into the believing community, and by communicating the grace of God’s promise eschatologically to make the world “whole.”
