Actually, Romans 9 1-13 is not quite as facile as just stating God is Sovereign.
Paul was concerned that he needed to explain to the Christian community the rejection of Christ by the Jews. He grieved over their unbelief. It also points to some concepts about election, Jacob who was chosen and Esau who was not.
Election in this case means that the gift of faith is an enactment of God’s mercy.
But, Lex, of course, you know passages.
I am interested in someone showing me how Marian devotions contradict scripture, because that is a very serious charge, and it is false. When that occurs, I will be happy to explain anything else.
