“Starting today I will obey my conscience. As a Christian I do not have the right to let these women and men die.”

1860s, What the Black Man Wants (1865)

Heretics and Heresies (1874)
Context: I do not say, and I do not believe, that Christians are as bad as their creeds. In spite of church and dogma, there have been millions and millions of men and women true to the loftiest and most generous promptings of the human heart. They have been true to their convictions, and, with a self-denial and fortitude excelled by none, have labored and suffered for the salvation of men. Imbued with the spirit of self-sacrifice, believing that by personal effort they could rescue at least a few souls from the infinite shadow of hell, they have cheerfully endured every hardship and scorned every danger. And yet, notwithstanding all this, they believed that honest error was a crime. They knew that the Bible so declared, and they believed that all unbelievers would be eternally lost. They believed that religion was of God, and all heresy of the devil. They killed heretics in defence of their own souls and the souls of their children. They killed them because, according to their idea, they were the enemies of God, and because the Bible teaches that the blood of the unbeliever is a most acceptable sacrifice to heaven.

1970s, Remarks on pardoning Nixon (1974)
Context: I have come to a decision which I felt I should tell you and all of my fellow American citizens, as soon as I was certain in my own mind and in my own conscience that it is the right thing to do.
I have learned already in this office that the difficult decisions always come to this desk. I must admit that many of them do not look at all the same as the hypothetical questions that I have answered freely and perhaps too fast on previous occasions.
My customary policy is to try and get all the facts and to consider the opinions of my countrymen and to take counsel with my most valued friends. But these seldom agree, and in the end, the decision is mine. To procrastinate, to agonize, and to wait for a more favorable turn of events that may never come or more compelling external pressures that may as well be wrong as right, is itself a decision of sorts and a weak and potentially dangerous course for a President to follow.
I have promised to uphold the Constitution, to do what is right as God gives me to see the right, and to do the very best that I can for America.
