Well, let's see:
1. Is the memorization and recitation of Masonic ritual a typical Lodge activity? Yes it is. Everyone with a speaking part in ritual is expected to be able to recite it from memory, though I'm sure many lodges fall short in this Masonic duty. This requires practice, much of which occurs in the lodge, thus making it 'typical.'
2. Does the new Mason have memory work he must accomplish and recite in open lodge? Yes, he does, at least in the normal process (see below). It's called the catechism, which may be long or short depending upon jurisdiction, and which must be satisfactorily completed before he can advance to the next degree. Perhaps your jurisdiction, whichever one that might be, no longer requires proficiency. If so, I'd say that would make it the exception.
3. Does each meeting involve quite a bit of recitation which must be in accordance with the ritual? Yes, it does. Opening and closing ceremonies, balloting, etc., are pretty formalistic and much of the meeting is from memory.
My comments were correct. Now let's look at your charges:
How true.
You cast a broad accusation which probably isn't true. Surely some of such men became Masons the traditional way.
Again, not sure if you are correct about that. According to Paul Bessel's website, some GL's do require proficiency (including memory work) for such men. It just depends on the GL in question.
Do I get tired of being wrong so often? I'll consider the question should it ever happen. Cordially, Skip.
