Christian, I really appreciate your writing. I heard a little of Tim Gordon today on the similar subject (don't normally listen to him because don't agree with a lot about his approach on things); I have a very different take. I am no way a prude, and have studied Theology of the Body (though I am a Consecrated Bride of Christ as a Canon 603 Hermit). The part that I heard, Tim shared that he may soon have a debate with you, and that you were leaning more toward his way of thinking. I don't know what you were before this article, but it definitely doesn't seem to match what Tim's views. You may find Mystical City of God by Ven. Mary of Agreda very interesting on this subject. She was reportedly revealed, regarding Joachim and Ann, that their nuptial act in bringing forth Mary, the Immaculate Conception, was raised above their flesh to a transcending act that allowed it to be fully pure (probably somewhat like it would have been in the Garden of Eve before the fall). Also, it is reportedly revealed to her, and to Maria Valtorta in Poem of the Man-God, that Eve's sin in the Garden was sexual, whether lust, and/or the desire to create themselves.
