It's fine to talk about people having missions in life, being called out from pagan nations or whatever; the point I was making is that this is not what the word
ekklesia means. It definitively does
not mean "called out ones" and to take it further to say "some are called out of Israel," as someone else had posted (sorry for the paraphrase) etc. is building a theology on a linguistics of sand.
None of the believers who were Jews were called out from Israel. Israel was not a pagan nation as the other nations were (like the land of Ur in your example). The tree which is Israel may be pruned, but believers in the Messiah who came/come from Israel are not called out of Israel; they remain in their tree, in the solid trunk. Others may be pruned out of it, and those born Gentile
can be grafted in to the trunk (i.e. convert, study the word etc. to make a strong graft). Then they are as immigrants who have obtained their rightful place in the kingdom of Israel (I don't mean the secular nation only).
No a synagogue did not become a church when they all accepted the Messiah; it remained a synagogue.
church is a totally alien word. It's funny how some English translations will translate the Greek
synagogey "church" when it's positive like a body of believers and translate the identical word
synagogue when something bad is going on there "i.e. the
synagogue of Satan."
A synagogue is just a gathering, Greek
synagao means "I gather together."
There is no "church," there is the
qehal-Yisrael which many many
ethnoi (ethnics as Paul calls them) have joined.
Ekkleisia in all likelihood expressed the idea of a sub-group within the synagogue community.

Jews were not called out of the Jewish community; the
ekkleisia was/is the Jewish community; there just happen to be MANY immigrants now
Hope you at least found this interesting guys.
