These so-called "priests" are no more of an "agent" than you. They are allowed to make the same bad choices as you. You are given the same authority as any pastor or priest or evangelist to do the right thing.
God does not stand on a mountaintop watching the disasters that befall mankind. He left the highest Heaven and came down to earth in the Person of His Son Jesus Christ. He intervened on behalf of the human race by demonstrating so deep a love for His creation to extend salvation to all who would receive Him. Still today God sends warnings of danger ahead, but many turn blinded eyes away; they shut their hearing off from the Voice that calls out to them.
