4th Church – Thyatira – Rev. 2. 18-29.
Period of the great Protestant Reform and the separation from Rome (invention of the press). The Bible started, in large scale, in only one book, in the hands of the people in 1517. In Germany, Luther, Catholic monk, protests against Rome’s leniency; followed by Calvin in Switzerland and King Henry VIII, in England, who wanted to get married again, and breaks with Rome, followed by other nations.
And the beginning of the reform is the choice of not being submissive to Jezebel (prostitute) Roman Catholic, that confirms.
22- Behold, I will cast her into a bed, and them that commit adultery with her into great tribulation, except they repent of their deeds.
23- And I will kill her children with death; and all the churches shall know that I am he which searcheth the reins and hearts: and I will give unto every one of you according to your works.

Means the plagues that hit Catholicism in that time, and the many persecutions of the Inquisition to countries and colonies that were still under Rome (their own sons) And Jesus says to the rest in Thyatira, those that were converted to the promise that if they kept the good work, will be prosperous the nations that choose the reform.
26- And he that overcometh, and keepeth my works unto the end, to him will I give power over the nations:
27- And he shall rule them with a rod of iron; as the vessels of a potter shall they be broken to shivers: even as I received of my Father.
28- And I will give him the morning star.
Like Jesus in 1st aprisco, spoke of 2nd aprisco. John 10.16-18 Jesus gave to the Angel Luther, the Protestant, a new beginning, the 2ºnd aprisco, with the Bible, after total domination of the beast, translating the Bible from Latin to German.
