I vote we give him a pass on this, not like he was in Hymietown making this statement. I mean we know there are no issues between Jews and blacks. Right?
It was just a slip of the tounge, maybe even just a smudge on the telepromper. 
The left would have done the same for GW. 
As far as I know there is no requirement for a President to have any faith in God or worship his or anyone Else's God.
We have had Presidents that were closet Atheists, this happens. The President is not there to make decisions on his faith, only the law of the land.
Why expect a President to worship God at all, can we expect a God less leader to lead us, who knows but many have in the past, Some did believe in in God, but not the Churched God others believed in.
Most of our founding fathers up to the present time were and are Masons. a deep belief in God, Country and Family. No one Church do they attend, some may never set foot in a Church or Temple but they believe and do the work they were set out to do perhaps before the pyramids were built.
When a leader comes about to claim he is of any religion and finds a way to get out of their duty, such as--
-- Christians are called to gather together with the sinners. these are from the bible the people the church was built for to rescue and give them comfort in the name of he lord. The Church was not built for those that were good and faithfull people, the Church was for the sinners to find peace in the name of the Lord.
Think I will had out to the Religion forum, I seem to be rilled up.
