Luther and Lewis

The advantage of this is that when Christians gather together, prayer is more powerful than at other times. We can and should most certainly pray at all places and hours, but prayer is nowhere so strong as when, in unity of Spirit, the whole congregation is gathered together to pray.—Martin Luther, Sermon, 1544

A man who jibbed at authority in other things as some people do in religion would have to be content to know nothing all his life.—C. S. Lewis, Business of Heaven, p. 269.
