'...to a Christian the true tragedy of Nero must not be that he fiddled while the city was on fire but that he fiddled on the brink of hell. You must forgive me for the crude monosyllable. I know that many wiser and better Christians than I in these days do not like to mention heaven and hell even in a pulpit. I know, too, that nearly all the references to this subject in the New Testament come from a single source. But then that source was our Lord himself. People will tell you that it is St Paul, but that is untrue. These overwhelming doctrines are dominical. They are not really removable from the teaching of Christ or his Church. If we do believe them, our presence in this church is great tomfoolery. If we do, we must sometime overcome our spiritual prudery and mention them.'
