The Call

As a tangent to the Rose Cross, see this section from the wiki entry:

"On the back side of the rosy cross is inscribed the motto of the Zelator Adeptus Minor at the bottom, 'The master Jesus Christ, God and Man.'"

And "it is a glyph, in one sense, of the higher Genius to whose knowledge and conversation the student is eternally aspiring."

Or as I call it, talking with (being called by) Museque.

Which reminds me of calls for Cthulhu.
