A change of identity is occurring in the international Church and in the Messianic remnant. The change is a switch from "them" to "us." This change of identity is to some degree a redefinition of the Ecclesia. It is the Church and Israel identifying one with another.
The books of Ruth and Esther describe real historic events, but may also be seen as parables with prophetic meaning. Ruth contains a message about the relationship between Israel and the Church. This is what we call "Ruth Ecclesiology." In a similar fashion, the book of Esther contains a message about the End Times. We call this: "Esther Eschatology."
