As we come to chapter 23, and the last days, Chris Watkin starts with the framework of 'Giving to to Caesar what is Caesar's and to God what is God's', and demonstrating that giving to Caesar is a subset of Giving to God. From this he shows that we can give to culture what is cultures.
He says Christians should be unusually open because they are unusually closed, and their cultural critique should be characterised by a love that can take many forms.
