Yes an atheist priest can perfectly minister to a believing congregation and miracles can happen in that congregation. Miracles depend on the faith of the believer, not that of the officiant. A bartender who never takes alcohol can serve alcohol to his clients. What is necessary is that the priest believes he is doing the good work. The congregation needs faith and it helps them. It would be evil to deny them such a service in the name of his lack of faith. - Bangambiki Habyarimana

From the club of what atheist call false hope and false god (which offer solace to weak minds), atheist are calling you to their club of no god and no hope (which offers nothing in return. Join the club only if you are a strong minded individual capable of handling your life alone without the help of gods. )

Atheism is not against god, it is against the religious establishment who use god they have never seen or heard from to establish their influence over the minds of men.

If you are a pastor there is no way you can lose faith without losing face, you are considered the devil incarnate by your former congregation

I am not an atheist. I simply believe in a god different from yours
