God for Priesthood or vice-versa

Discussing in the Theodicy class this day about the goodness of God, I began clarifying the term 'good'. Using the definition given by Aristotle of good, as that which is desireable, I raised the objection: If God is not desired by anyone, will His goodness reduce? Explaining the arguments of Thomas Aquinas, I clarified the meaning of God being good and we being good, to arrive at God as the summum bonum, the best of the best! I concluded the class with this argument: Is God desired for Himself or as a means? Now this is possible only when God is seen as good. To the extent that we see God as good, to that extent we desire and crave for Him. If not He is one among the list of things we desire. My final question to the Brothers was maybe a bit too blunt but I made my point: Do you desire God as a means for Priesthood or Priesthood as a means for God?
