The topic I have been asked to address is impossibly broad, so I have narrowed it in order to do five things. In the first section, some of the acrimonious sexuality debates in various Protestant churches during the last decade are described. Attention to these might show, empirically, how Protestantism handles, or rather fails to handle, questions about sexuality. Secondly, some tentative conclusions are drawn. In section three, appeals to the Bible as a source of authority are examined. Some remarks are made about the models of authority and tradition in the recent ARCIC document, The Gift of Authority ¹ in the fourth section. Finally, it is suggested that the Catholic and Protestant traditions should address common problems afflicting both of them.
