”The child to be born will be called holy, the Son of God”

In keeping with the season, Paul and Dan consider the concept of "the Son of God".  They consider examples of that phrase throughout the Bible, but concentrate on what it means for Jesus to be the only son of the Father. How can Jesus uniquely be called the Son of God?  Does calling him the Son of God make him Deity in any sense?  What is Jesus claiming when he says he is the Son of God?  All these questions and more are considered - including which are Paul and Dan's favourite carols!
