Again, this work of the Brethren was important because it was thorough and systematic. At first the missionaries were compelled to go out with very vague ideas of their duties. But in 1734 the Brethren published "Instructions for the Colony in Georgia"; in 1737 "Instructions for Missionaries to the East"; in 1738 "Instructions for all Missionaries"; and in 1740 "The Right Way to Convert the Heathen." Thus even during those early years the Moravian missionaries were trained in missionary work. They were told what Gospel to preach and how to preach it. "You are not," said Zinzendorf, in his "Instructions," "to allow yourselves to be blinded by the notion that the heathen must be taught first to believe in God, and then afterwards in Jesus Christ. It is false. They know already that there is a God. You must preach to them about the Son. You must be like Paul, who knew nothing but Jesus and Him crucified. You must speak constantly, in season, and out of season, of Jesus, the Lamb, the Saviour; and you must tell them that the way to salvation is belief in this Jesus, the Eternal Son of God." Instead of discussing doctrinal questions the missionaries laid the whole stress on the person and sacrifice of Christ. They avoided dogmatic language. They used the language, not of the theological world, but of the Gospels. They preached, not a theory of the Atonement, but the story of the Cross. "We must," said Spangenberg, "hold to the fact that the blood and death of Jesus are the diamond in the golden ring of the Gospel." But alongside this Gospel message the Brethren introduced as far as possible the stern system of moral discipline which already existed at Herrnhut. They lived in daily personal touch with the people. They taught them to be honest, obedient, industrious, and loyal to the Government. They opened schools, taught reading and writing, and instructed the girls in sewing and needlework. They divided their congregations, not only into "Choirs," but also into "Classes." They laid the stress, not on public preaching, but on the individual "cure of souls." For this purpose they practised what was called "The Speaking." At certain fixed seasons, i.e., the missionary, or one of his helpers, had a private interview with each member of the congregation. The old system of the Bohemian Brethren was here revived.[89] At these private interviews there was no possibility of any moral danger. At the head of the men was the missionary, at the head of the women his wife; for the men there were male "Helpers," for the women female "Helpers"; and thus all "speakings" took place between persons of the same sex only. There were three degrees of discipline. For the first offence the punishment was reproof; for the second, suspension from the Communion; for the third, expulsion from the congregation. And thus the Brethren proved up to the hilt that Christian work among the heathen was not mere waste of time.
