"Others arose from century to century to echo this protest. And those early teachers who, traversing different lands and known by various names, bore the character of the Vaudois missionaries, and spread everywhere the knowledge of the gospel, penetrated to the Netherlands. Their doctrines spread rapidly. The Waldensian Bible they translated in verse into the Dutch language. They declared “that there was great advantage in it; no jests, no fables, no trifles, no deceits, but the words of truth; that indeed there was here and there a hard crust, but that the marrow and sweetness of what was good and holy might be easily discovered in it.”— Ibid. 1:14 . Thus wrote the friends of the ancient faith, in the twelfth century. GC 238.1"
"Therefore they that were scattered abroad went every where preaching the word."
The EGW passage describes the Vaudois missionaries spreading the gospel, which directly parallels the scattering of believers in Acts 8:4 who went everywhere preaching the word. The connection is strong and meaningful.
