I'll be joining the Knights of Columbus soon. They are a wonderful institution and I commend their history to you.
However, today I came across this picture of the Grand Master of the Knights of Malta, Fra Andrew Bertie, from his recent meeting with the Holy Father. This guy looks incredible. I also saw some of the Knights of Malta at the Installation Mass of Archbishop Wuerl of Washington, DC. These people know how to dress up.
The Knights of Malta have an interesting and long history. Here it is from Wikipedia.
