But the worst feature of this riotous life is still to be mentioned. If there is any topic requiring delicate treatment, it is surely the question of sexual morality; and now the Count made the great mistake of throwing aside the cloak of modesty and speaking out on sins of the flesh in the plainest possible language. He delivered a series of discourses on moral purity; and in those discourses he used expressions which would hardly be permitted now except in a medical treatise. His purpose was certainly good. He contended that he had the Bible on his side; that the morals of the age were bad; and that the time for plain speaking had come. "At that time," he said, "when the Brethren's congregations appeared afresh on the horizon of the Church, he found, on the one hand, the lust of concupiscence carried to the utmost pitch possible, and the youth almost totally ruined; and on the other hand some few thoughtful persons who proposed a spirituality like the angels." But again the Brethren rode their horse to death. They were not immoral, they were only silly. They talked too freely about these delicate topics; they sang about them in their hymns; they had these hymns published in a volume known as the "Twelfth Appendix" to their Hymn-book; and thus they innocently gave the public the impression that they revelled, for its own sake, in coarse and filthy language. What judgment are we to pass on all these follies? For the Brethren we may fairly enter the plea that most of them were humble and simple-minded men; that, on the whole, they meant well; and that, in their zeal for the Gospel of Christ, they allowed their feelings to carry them away. And further, let us bear in mind that, despite their foolish style of speech, they were still heroes of the Cross. They had still a burning love for Christ; they were still willing to serve abroad; and they still went out to foreign lands, and laid down their lives for the sake of Him who had laid down His for them. As John Cennick was on his visit to Herrnhaag (1746), he was amazed by the splendid spirit of devotion shown. He found himself at the hub of the missionary world. He saw portraits of missionaries on every hand. He heard a hymn sung in twenty-two different languages. He heard sermons in German, Esthonian, French, Spanish, Swedish, Lettish, Bohemian, Dutch, Hebrew, Danish, and Eskimo. He heard letters read from missionaries in every quarter of the globe. "Are you ready," said Zinzendorf to John Soerensen, "to serve the Saviour in Greenland?" "Here am I, send me," said Soerensen. He had never thought of such a thing before. "But the matter is pressing; we want someone to go at once." "Well!" replied Soerensen, "that's no difficulty. If you will only get me a new pair of boots I will set off this very day. My old ones are quite worn out, and I have not another pair to call my own." And the next day the man was off, and served in Greenland forty-six years.
