How is it that people who are quite obviously eaten up with Pride can say they believe in God and appear to themselves very religious? I am afraid it means they are worshipping an imaginary God. They theoretically admit themselves to be nothing in the presence of this phantom God, but are really all the time imagining how He approves of them and thinks them far better than ordinary people: that is,they pay a pennyworth of imaginary humility to Him and get out of it a pound's worth of Pride towards their fellow-men.
