What is the Master Craftsman II? Is it continuing education for blue lodge? Sounds interesting!
It's a program offered to Scottish Rite masons. Once you become a Scottish Rite mason and receive your degrees you can get in the program. Master Craftsman I can be obtained from the Scottish Rite website. For $35 you get a six session course and the necessary books. Once you've completed the six sections you receive a certification and pen. Usually your Valley will present it to you in a stated meeting. Upon completion of Master Craftsman I you can enroll, for another $35 in Master Craftsman II.
Master Craftsman I teaches you the ropes and history of the Scottish Rite with some of the allegory thrown in. Master Craftsman II takes you for a closer look at the 29 additional degrees of the Scottish Rite.
Here's my pitch. If you aren't a member of the Scottish Rite and you have interest in further explanation of masonry, history, or philosophy, you will enjoy the Rite. The Rite is not for everyone. But it is well worth the effort for the open-minded and seeker of allegory. Though called "Scottish" the degrees are mostly French with a few German influences.
Like masonry in general, you will find nothing in the Scottish Rite contrary to your own particular religious creed. You will, however, learn toleration of others. You will find all masonic tenants stressed and supported with each following degree.
