For my theologising I have to read a chap called Patrick Miller
On the second command, and the tendency for us to make theological graven images, he says this:
theology is a very dangerous game and always teeters on the brink of idolatry, with the tendency, intentional or not, of seeking to get at God for our own well-being and program
P58
