I've been enjoying the theological discussions taking place in your most recent podcasts. I came to make two, hopefully not merely pedantic, points about what you have been talking about recently concerning baptism and the first sin of man.
The first is that I was surprised you guys did not mention that baptism is explicitly a ritual involving the symbolic death of the participant. From the online catechism, " This sacrament is called Baptism, after the central rite by which it is carried out: to baptize (Greek baptizein) means to "plunge" or "immerse"; the "plunge" into the water symbolizes the catechumen's burial into Christ's death, from which he rises up by resurrection with him, as "a new creature." This is one of the reasons why baptisms are often done around Easter.
Secondly, and, I think, more importantly, is that you guys said a number of times that the first sin of man was in desiring knowledge, but this isn't quite right. The small but important distinction to make is that Adam's sin was not in desiring knowledge, but in desiring knowledge in an improper way. The serpent tempted Eve not simply with knowledge, but knowledge that was like God's knowledge. The serpent says, "For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil." So, the temptation here isn't in knowing good and evil, but in becoming "as gods".
This is one of the reasons why I have so much trouble with the epigram to this story, especially the last line. Of the things mentioned in the quote, the desire to know is, I think, essentially different from the others because humans are, by nature, ordered towards knowledge, and to give that up a truly radical sacrifice. But I realize, just as I am typing this, that must be the point. Saints are fucking awesome.
