Francis Scott Key's Anthem
...Key began to practice law in Washington, D.C. Even in the busiest of times, Key never failed to conduct family prayers in his home twice a day, always including the servants in these family devotions. ...
...Key's Christian convictions were intense and influenced all his relations and actions. At one time, in 1814, he even considered entering the ministry. Though he decided to remain in his law career, his Christian beliefs continued strong and his Christian work active throughout his life. Among those whose faith Key’s help sustained was John Randolph of Roanoke. Randolph had had his faith shaken by reading Voltaire and other Enlightenment authors. In a letter to Randolph, Key wrote his own views, which still contain excellent apologetic advice for today:
I don't believe there are any new objections to be discovered to the truth of Christianity, though there may be some art in presenting old ones in a new dress. My faith has been greatly confirmed by the infidel writers I have read. Men may argue ingeniously against our faith, as indeed they may against anything -- but what can they say in defense of their own -- I would carry the war into their own territories, I would ask them what they believe -- if they said they believed anything, I think that they might be shown to be more full of difficulties and liable to infinitely greater objections than the system they oppose and they were credulous and unreasonable for believing it. If they said they did not believe anything, you could not, to be sure, have anything further to say to them. In that case they would be insane, or at best ill qualified to teach others what they ought to believe or disbelieve. ...
