Parable of the mustard seed

This is what I believe.  Jesus predicted everything with his parables.  The mustard seed that grew into a tree.  Represents the infrastructure of the church but it has over grown its useful size (the analogy of a plant becoming a tree).  I happen to feel that the tree represents the secret societies as well.  So the parable has multiple applications.

In my alternate view the secret societies have become pervasive.  They constitute a hidden plutocracy.  But the rank and file are fooled. They feel it is a bottom up structure.  The plutocracy and the true evil intent are masked by the secrecy. As only the top tier knows the truth.  But the blackbirds resting in the tree in the parable represent the top of the hierarchy.

The blackbirds have infiltrated the government usurping control of certain things, the church with false teachings, basically not paying attention to the only thing Christ had said we must do, love our fellow man.
