Who stands fast? Only the man whose final standard is not his reason, his principles, his conscience, his freedom, or his virtue, but who is ready to sacrifice all this when he is called to obedient and responsible action in faith and in exclusive allegiance to God the responsible man, who tries to make his whole life an answer to the question and call of God. Where are these responsible people?

To-day we have fewer dogmas, but I think that we have stronger principles. By a dogma I mean a deduction from facts which is only valid under certain conditions, and which becomes untrue if those conditions change. By a principle I mean something that is an eternal and universal truth.
