But contrary to Tickle’s statement it is precisely God’s word and its authority that holds, keeps, and constantly returns the church back to her Lord.
Because of the word of God orthodox Christianity can often be traced in unbroken movements across continents and time. (No need for five-hundred year paradigms here.) Wycliffe connects to John Hus and Hus to the Bohemian Brethren, they to the Moravians, and as most know, John Wesley in the middle of a storm at sea, found true conversion to Christ among the Moravians. Such a history occurs because of God’s word and its authority. On the essentials they were in agreement and the Word of God informed them and was heard by them.
Of the English reformer, Wycliffe (1328-1384), historian William Estep writes:
For Wycliffe the authority of the Bible was supreme. … For Wycliffe the Bible was not just one authority among many—i.e., tradition and the church; it alone stood above all authorities. “Neither the testimony of Augustine nor Jerome, nor any other saint,” he wrote “should be accepted except in so far as it is based on Scripture.”Before his death Wycliffe trained a group of men to teach what he had proclaimed. The message went as far as Bohemia and there it took root. As historian Kenneth Scot Latourette points out it was probably helped by the devout Bohemian wife of England’s King Richard II. Anne of Luxemburg, sister of Bohemia’s king, brought with her, to England, “Copies of the Bible in Latin, German and Czech” and at the same time some Bohemian students studied at Oxford, Wycliffe’s school. 
In Bohemia John Hus (around 1373-1415) read the writings of Wycliffe. (While he did not agree with all of Wycliffe’s thoughts he did agree with their substance) Hus was a popular preacher and university lecturer. As Estep points out “His influence was enormous. Even the archbishop, following his lead, had declared fornicating priests to be heretics.”
After Hus’s martyrdom, he was burnt at the stake, this desire for both a moral lifestyle among the clergy and biblical teaching was insisted on by Hus’s followers. Latourette writes of them:
One [of the groups], aristocratic, known as the Utraquists because in communion they gave both the bread and the wine to the laity, wished the free preaching of the gospel and a moral clergy and stood against only those practices of the Catholic church which they regarded as forbidden by the Bible. Another group was the Taborites who never realigned with the Catholic Church but were always a separate body. In Bohemia around the 15th century the Bohemian Brethren were formed. They seemed, as Latourette states “to have been made up of elements from the Utraquists, Taborites and Waldensees.” He also writes that his readers would meet them again as “spiritual ancestors of the Moravians.”
The Bohemian Brethren were terribly persecuted and were often an underground group. Many of them were influenced by Lutheranism, others by Swiss Calvinism. In 1722 some Protestants from both Bohemia and Moravia fled Catholic persecution and found refuge in what is now Germany. Nicolaus Ludwig, Count of Zinzendorf gave them refuge on his estates, “They founded the village of Herrnhut on his property, he identified himself with them and became a bishop of their church, and through him missionaries from among them went out to various parts of the world.” 
The Moravians still exist today and are in communion with the Presbyterian Church (U.S.A.). And they also are in battle over the authority of Scripture and homosexuality. They, in 1990-93, began seriously dealing with that issue. They did not come to a consensus as they must in their voting. But all of the horrible pushy agenda that has been aimed at the orthodox in all of the mainline churches is there.
Who do we listen to—that was one of the questions asked when I wrote about my church leaving while I stay on in a denomination which has forgotten, as Martin Luther put it, that their most important function as a Christian is to listen to the word of God, the Bible. We must listen to the Lord of the Church, Jesus Christ, and to his word the Bible.
