If the substance of God was only the opinions of man, perhaps even the sum of them, 

. . . The world would be exactly as we find it.  

Every man pursuing the best of his own mind;

Mindless of the minds around him.  

Violence: 

from murder to war 

from jealousy to revenge

from specialized inclusion to utter distain

from dutiful servitude to despicable rebellion.  

Yes.  

If the substance of God was only the opinions of man, wouldn’t we see exactly what we do?

Scatter the people so that they cannot construct together. Destroy solidarity.  

The nature of what we worship matters intensely. 

Define Christianity.
