Scottish Rite has been called the “college of Freemasonry” for it’s further Masonic education of the 4°-32° degrees. They are not advanced degrees beyond that of Master Mason in the Blue Lodge; instead, the Scottish Rite Freemasonry degrees are further education on the principals of the Blue Lodge.
The Scottish Rite makes application of the doctrines of Freemasonry to every realm of human activity. The individual Mason is taught to put into practice in his personal life and thought the lessons learned in the Blue Lodge.
Socially, the Scottish Rite is Freemasonry Militant, not in the sense of propaganda and agitation, nor by endorsing specific causes or sponsoring particular political movements, but by showing through illustrations from history and human evolution how the Mason may make his influence felt for the principles of free thought, free government, free education, and free religion. The Scottish Rite Mason is the foe of intolerance, bigotry, and ignorance in all their forms. That is what the Scottish Rite Degrees are all about.
After the Blue Lodge, a Master Mason may receive further teachings through the Scottish Rite. The Scottish Rite can confer an additional 30 degrees to the Master Mason.
