Above all things, lose no occasion of exercising your dispositions to be grateful, to be generous, to be charitable, to be humane, to be true, just, firm, orderly, courageous, etc. Consider every act of this kind as an exercise which will strengthen your moral faculties and increase your worth.
Thomas JeffersonReason and free inquiry are the only effective agents against error. Give a loose to them, they will support the true religion by bringing every false one to their tribunal, to the test of their investigation. They are the natural enemies of error and error only. Had not the Roman government permitted free inquiry, Christianity could never have been introduced. Had not free inquiry been indulged at the era of the Reformation, the corruption of Christianity could not have been purged away.
Thomas JeffersonCreeds have been the bane of the Christian church ... made of Christendom a slaughter-house.
