I want to know the answer to the following question:
What concept is based on adherence to Masonic Landmarks, basic membership requirements, and tenets and rituals of the craft?
All the background I'm provided with is that "Essentially, every Grand Lodge will hold that its landmarks (its requirements, tenets and rituals) are Regular, and judge other Grand Lodges based on those.". Is that enough to answer the question?
Answer: no
