While campaigning for the presidency, Abraham Lincoln was challenged by some religious leaders for not being affiliated with any particular church. Abe admitted that he was not formally associated with a church. When asked why, he replied that he was somewhat confused by the many conflicting demands of the various denominations. He then went on to say that he would be proud to belong to any church that taught and practiced the quote from the tenth chapter of St. Luke: “Jesus asks what is written in the law? How do you read it?” The questioner replied, “You shall love the Lord your God with all your heart, with all your soul, with all your strength, with all your mind and your neighbor as yourself.” He could have answered correctly, “Do this and you shall live.”
I have read several biographies of Abraham Lincoln and in my opinion he lived by that and could well be considered a saint.
