A) I take the Creation story of Genesis completely in a metaphorical way. I believe that all stories from the Scriptures should be taken metaphorically in the light of science and reason; I would hardly think that the whole purport of Jesus' teachings lie in his supremacy. After all, John's Gospel is the only weird one that gives Jesus as not only the Messiah, but as the very Son of God Himself.
In the other Gospel accounts, we see a Jesus who is committed towards a social Gospel, a Gospel of loving actions and of good works, to bring healing and the power of healing to people of all walks of life and of all faiths, whether Jew, Gentile or Samaritan.
The story of Genesis is to show that God has given agency to all his creatures, but Satan (representing the lower nature, forces, or the carnality of the human being, for I do not believe in a literal personified being of evil called Satan or the Devil) attempts to destroy that agency through ignorance and the natural forces. However, if it was not for the Fall, then there would be no understanding of good and evil, of morality and discrimination.
In the Book of Mormon, it is taught that there must be an opposition in all things to distinguish what is good and what is bad. In the Book of Moses, Eve, the wife of Adam, says thus:
"Were it not for our transgression we never should have had seed, and never should have known good and evil, and the joy of our redemption, and the eternal life which God giveth unto all the obedient."
-- Moses 5:11
Thus, the story of Genesis regarding the Garden of Eden and the so-called 'Fall of Adam' is an allegory to describe that God's gift to mankind is agency, and through that gift of intellectual discrimination, we can know good from evil, and choose the good.
"And now, behold, if Adam had not transgressed he would not have fallen, but he would have remained in the garden of Eden. And all things which were created must have remained in the same state in which they were after they were created; and they must have remained forever, and had no end.
And they would have had no children; wherefore they would have remained in a state of innocence, having no joy, for they knew no misery; doing no good, for they knew no sin.
But behold, all things have been done in the wisdom of him who knoweth all things.
Adam fell that men might be; and men are, that they might have joy."
-- 2 Nephi 2:22-25
B) At this point in time, I am unsure... I guess my theological position would place me as part of Community of Christ (RLDS)... my religious affiliation is another complex thing altogether, lol.
