But they didn't do that. Instead, they worked to put all religions into the free market, to rise or fall each on their own merits.
Our Founders put their own prejudices on the back burner and worked to have freedom of religion and not just mere tolerance.
Otherwise, we would never have had a Bill of Rights nor a Constitution designed to include all religions, including Catholic.
Washington and Jefferson were members of the Episcopal Church, but were probably deists like the majority of the Founding Fathers, who didn’t ascribe to any particular religion. In all their writings they hardly ever refer to Jesus Christ, or God, but instead refer to a Supreme Being, Author of the Universe, Creator, etc. Washington would occasionally say Christian in his writings, but most scholars don’t think he was Christian. They all believed in God, no matter what they called Him.
