SCOTTISH FREEMASONS

"You must conceal all the crimes of your brother Masons, except murder and treason, and these only at your own option, and should you be summoned as a witness against a brother Mason be always sure to shield him. Prevaricate [falsify], don't tell the whole truth in his case, keep his secrets, forget the most important points. It may be perjury to do this, it is true, but you're keeping your obligations, and remember if you live up to your obligation strictly, you'll be free from sin." (Edmond Ronayne, "Masonic Handbook," page 183)
