Don't expect perfection in a man because he is a Freemason. If you do, you will be disappointed. Masonry makes a man better, but no human agency can make him perfect.
If he is a Mason, you have a right to presume he is a good man, but do not condemn Masonry even if a few Masons turn out bad. Even the Great Teacher Himself had a Judas.
The aim and purpose of Masonry is to receive none but good men, keep them good and make them better. Judge the institution not by a few failures, but by the average of its successes.
That average is high and it consequently gives standing to its members, but it cannot be an infallible guide.
