There are organizations related to Masonry, usually called Concordant bodies, which, to join, require Masonic membership. The two most notable are the York Rite and the Scottish Rite. The 33rd degree is an honorary degree in Scottish Rite. It is NOT a higher degree. There is no degree higher than the Third Degree or Master Mason and no higher honor can be given to any Mason than the White Lambskin Apron that all Masons wear with pride.
