The most useless group in the Church.
Our family was involved with the Knights - and Fourth Degree at that.
It was meant to be a Catholic response to the Masons - in its day it did good work and it did give Catholic men a group foothold.
However, it went New Church lock, stock and barrel, and is indeed quite friendly with the Masons now (how the Masons laugh at this).
They were proud to wear the uniforms back in the day - but the younger folks probably don't go for it and so they tone down the entire design. Probably less expensive, too.
Another shame thanks to Vatican II.
