This is true, indeed, that God is not bound, neither to Jerusalem nor to any other place, and that He is able to save also elsewhere. No one will deny this. But try it and see what you will get! If you invent forms of worship according to your own judgment, you will be in danger of God’s wrath. By His almighty power God could save the human race without Christ, without Baptism, and without the Word of the Gospel. He could have illuminated men’s hearts inwardly through the Holy Spirit and forgiven their sins without the ministry of the Word and of ministers. But it was not His will to do so. And God very strictly prohibited all erring forms of devotion and worship.

Luther, AE 6
