After joining 32nd Degree Scottish Rite Freemasonry™, you should not demit from your Masonic lodge. Termination of your membership in a Masonic lodge for any reason automatically terminates your membership in the Scottish Rite.
32nd Degree Scottish Rite Freemasonry™ is an appendant body of Blue Lodge Freemasonry and, as such, membership in the Blue Lodge is a requirement for membership in the Scottish Rite.
