Biblically we may expect this to be different, for God to see the individual potential and not the dynasty, and jet Judaism is in itself a dynasty of the greatest proportion. I understand in light of this why the genealogy of Jesus is considered such a huge heal, and yet somehow I want to believe that a mans destiny is not foretold by his fathers but rather than by the individuals response to the world. Yet the bigger the biblical character the more we see the privilege of their upbringing, the pureness of their blood. Even characters like Moses were brought up in the luxury of the few, a luxury they had no active part of.
No matter how many times i hear the mantra 'give me a boy until he is seven and i will show you the man' i still want to believe that we are more than the first 2555 days of our lives. Half of those days we won't have a chance of remembering and way more than half again will slip away from us chunk by chunk. These are the days where we explore life, but we are heavily protected, the days when responsibilities are few but freedom is normally tightly curbed.
I still sit with the tension, one that leave many characters as bit parts in the bible. Jesus did clearly break the cycle but the loudest voice in the early church was a well educated Jew and Roman citizen. I wonder if we are somehow inbuilt to expect a certain background from those in leadership and as such no matter how much more face time the fishermen got, the scholar would always win the battles of authority?
