When the Saxons invaded Britain, heathenism gained control. The conquerors disdained to be instructed by their slaves, and the Christians were forced to retreat to the mountains and the wild moors. Yet the light, hidden for a time, continued to burn. In Scotland, a century later, it shone out with a brightness that extended to far-distant lands. From Ireland came the pious Columba and his co-laborers, who, gathering about them the scattered believers on the lonely island of Iona, made this the center of their missionary labors. Among these evangelists was an observer of the Bible Sabbath, and thus this truth was introduced among the people. A school was established at Iona, from which missionaries went out, not only to Scotland and England, but to Germany, Switzerland, and even Italy. But Rome had fixed her eyes on Britain, and resolved to bring it under her supremacy. In the sixth century her missionaries undertook the conversion of the heathen Saxons. They were received with favor by the proud barbarians, and they induced many thousands to profess the Romish faith. As the work progressed, the papal leaders and their converts encountered the primitive Christians. A striking contrast was presented. The latter were simple, humble, and scriptural in character, doctrine, and manners, while the former manifested the superstition, pomp, and arrogance of popery. The emissary of Rome demanded that these Christian churches acknowledge the supremacy of the sovereign pontiff. The Britons meekly replied that they desired to love all men, but that the pope was not entitled to supremacy in the church, and they could render to him only that submission which was due to every follower of Christ. Repeated attempts were made to secure their allegiance to Rome; but these humble Christians, amazed at the pride displayed by her emissaries, steadfastly replied that they knew no other master than Christ. Now the true spirit of the papacy was revealed. Said the Romish leader: “If you will not receive brethren who bring you peace, you shall receive enemies who will bring you war. If you will not unite with us in showing the Saxons the way of life, you shall receive from them the stroke of death.”(98) These were no idle threats. War, intrigue, and deception were employed against these witnesses for a Bible faith, until the churches of Britain were destroyed, or forced to submit to the authority of the pope. In lands beyond the jurisdiction of Rome, there existed for many centuries bodies of Christians who remained almost wholly free from papal corruption. They were surrounded by heathenism, and in the lapse of ages were affected by its errors; but they continued to regard the Bible as the only rule of faith, and adhered to many of its truths. These Christians believed in the perpetuity of the law of God, and observed the Sabbath of the fourth commandment. Churches that held to this faith and practice, existed in Central Africa and among the Armenians of Asia.
