"It is not up to our hierarchy to determine or decide who is naturally allowed to be called to any vocation, based on their flesh."

You do not understand basic Catholic belief.
You believe the Church is just another HUMAN organization, with decisions being made strictly on a natural basis, guided by -'flesh'.

The Church is guided by the HOLY SPIRT.
The Church has survived 2000 years, and is stronger than ever, in spite of 2000 years of persecution, misrepresentation and attacks.

Christ said to Peter: "Upon this rock I will build my Church, and the gates of hell shall not prevail against it" (Matt. 16:18).  

And you are wrong, it IS up to the hierarchy to determine or decide - through the guidance of the HOLY SPIRT - who is allowed to be called to any vocation.

Once again, the Church is not, never has been, nor never will be - a 'democracy'.
