Actually I should like to say that in this case too the words you utter or what you think as you utter them are not what matters, so much as the difference they make at various points in your life. How do I know that two people mean the same when each says he believes in God? And the same goes for belief in the Trinity. A theology which insists on the use of certain particular words and phrases, and outlaws others, does not make anything clearer (Karl Barth). It gesticulates with words, as one might say, because it wants to say something and does not know how to express it. Practice gives the words their sense.
