“Not voting is ugly,” the 87-year-old pontiff said. “It is not good. You must vote.”
“You must choose the lesser evil,” he said. “Who is the lesser evil? That lady, or that gentleman? I don’t know."
"Everyone, in conscience, (has to) think and do this.”
-- Pope Francis, quoted here
Since your most serene majesty and your highnesses require of me a simple, clear, and direct answer, I will give one, and it is this: I cannot submit my faith either to the pope or to the council, because it is clear that they have fallen into error and even into inconsistency with themselves. If, then, I am not convinced by proof from Holy Scripture, or by cogent reasons, if I am not satisfied by the very text I have cited, and if my judgment is not in this way brought into subjection to God's word, I neither can nor will retract anything; for it cannot be either safe or honest for a Christian to speak against his conscience. Here I stand. I cannot do otherwise. God help me. Amen.
-- Martin Luther, quoted here
