The Period of Judges and the Period of Christian Churches under the Patriarchal System
The period of Judges is the 400-year period after the Israelites, led by Joshua and Caleb entered Canaan. In this period these judges each filled multiple functions of prophet, chief priest and king.
The period of Christian churches under the patriarchal system is when the Christians were led by the patriarchs, whose duties, from the standpoint of the restoration providence, corresponded to those of the judges.
The period of Judges is when the foundation of Israelite feudal society began centering on the judges in the new land allotted to each tribe.
Likewise, after Christianity's liberation from the Roman Empire, the Gospel was spread to the Germanic tribes who had moved to Western Europe because of the 4th century invasion of the Huns (from Mongolia). There, in the new land of Western Europe, they established the foundation of Christian feudal society.
