Most Southern Baptist churches I went to taught that God would restore Israel to himself as he promised; and that the Church was made up of all believers from all tongues and tribes. However, the church was definitely not a replacement Israel in terms of what Israel becomes during the 1000 year reign of Christ!
The USA has the MOST Christians in the world who don’t go along with Replacement Theology, but it’s pretty much the norm for rest of the Christian world.
You’ll find Replacement Theology doctrine in the Catholic Church, in the Lutheran Church and in the Presbyterian Church.
Where you encounter “Covenant Theology” you’ll encounter the idea that Israel has NO PLACE in God’s plans for the future (i.e., in prophecy). In other words, Israel has no more significance in God’s prophetic plans than does Malaysia or Sweden, or South Africa or Botswana.
Covenant Theology is rabidly opposed to Dispensationalism ... and Dispensationalism is the strongest source of support for Israel as prophetically significant in God’s plans for the future.
