Washington was dedicated to attending Church and had pews in several churches. George Washington's adapted daughter who was Martha's granddaughter, who lived with George for twenty years said you 'that one might as well question Washington's patriotism as question his Christianity'. Of course I am sure today's athiests know Washington's faith better than his family did. Calling Washington a Deists is just ignorant.
And people might have said the same about me because I attended churches before coming to know the Lord. The fact remains even if Washington did know the Lord the revolution was in violation of Romans 13
