Please explain "replacement theology". I've never heard of the term before now.
The term replacement theology is one given to your system by those who disagree with it.
I happen to completely agree with you; I would call it a covenantal understanding of Scripture. The Church did not REPLACE Israel; it is a partial fulfillment of the OT promises to Israel. A down payment on the ultimate conclusion to history; the New Heavens & New Earth.
The modern nation state of Israel has no more to do with the redemptive purposes of God than Argentina or Bosnia.
