On The Church and Doctrine - McGrath

A Church that takes doctrine seriously is a Church that is obedient to and responsible for what God has entrusted to it. Doctrine gives substance and weight to what the Christian Church has to offer the world. A Church that despises or neglects doctrine comes perilously close to losing its reason for existence and may simply lapse into a comfortable conformity with the world—or whatever part of the world it happens to feel most at home with. Its agenda is set by the world; its presuppositions are influenced by the world’ its outlook mirrors that of the world.
