Question. How do you call Christ the only Son of God, since the godly are also called the children of God?
Answer. Because Christ is the only natural Son of God, of one substance with the Father. And we, being by nature the children of old Adam, are made the children of God by adoption, grace, and favor through Christ our Savior.
