As we saw, from Abraham through David, Yahweh pledged that he would be Israel’s God and Israel would be his special people. However, despite God’s fidelity, the covenant consistently came apart due to the people’s sin.

And this is precisely what, in their more philosophically accented language, the fathers of the Council of Chalcedon were saying.
