Re: The Eye and the Pyramid
"Invoke" can mean more than one thing: it has the traditional denotation of "To call upon for prayer or worship"; it can also mean "To summon a presence for a ritual or a specific purpose of the priest."
The latter meaning usually is the one used in occult practices, as in the invocation of Asmoday, etc. If this is truly the intention of the Freemason rituals then I would caution anyone not to open the door to demonic pacts or interplay of spirits.
On the other hand, if I had no knowlegde of Christ I would consider membership in a lodge very worthwhile and valuable.
