Is there an inverted structure for Mark 1. The chapter begins in the wilderness with John Baptist and ends in the wilderness with  Christ.  The call of Simon, Andrew , James and John in verse 16-20 matches the visit to the house “of Simon and Andrew, with James and John” in verse 30. The central pericope is the unclean spirit in the synagogue at Capernaum. 

A. 1:2-13 with John Baptist and Jesus “in the wilderness”.

B. 1:16-20 the call of Simon, Andrew, James and John by the shore of Galilee.

C. 1:21-29a. In the synagogue – the cleansing of a man with an unclean spirit. 

B’. 1:29b-34  In the house of Simon and Andrew with James and John

A’. 1:35-45 With Jesus “in desert places”.
