1]  The Body of Christ is What?  It was a term that meant the Church and the Church is the People of God.  Secondly, you have a 'gripe' with Vatican II.  It was legitimate Council with more bishops, from every place on the planet, than any other Council that was ever held[2,190 attending the first session of the Council].

2.  Old institutional concepts are just that.  They are no more "God's Laws" than the laws that stated that Catholic should not eat meat on Fridays.  This law was subjective, because areas of the world, did not have to follow them [Latin America did not].

3) The old white man with the beard is no more in my imagination than is Michaelangelo's painting of the Creation of Man in the Sistine Chapel.  And this concept of God is how most people picture God.  And that is no figment of my or anyone's imagination.  THIS is how God has been pictured in art down through the centuries even to today.   And this view of God is from an OLDER tradition---not today's.
