Adult Bible Study - Being Lutheran - Chapter 1: Closed

We've started a congregation wide Bible Study based on the book "Being Lutheran" by Rev. A. Trevor Sutton.  Each session will be based on one of the chapters of this book.

This bride of Christ, the Church, is open because of the Gospel.  But how much has it become a closed worship social group?  How can we be opened by the Gospel to proclaim it openly?
