Literally, "mystagogy" (pronounced mys-ta-go-gē) means leading those who have been initiated into a mystery into its deeper meaning and significance.
The early Church appropriated this term to refer to what was done during the great fifty days from Easter to Pentecost when they were leading newly-illumined converts into a deeper appreciation of the Sacred and Divine Mysteries they were experiencing (particularly through their Baptism and participation in the Eucharist) as it related to how they would live their lives and die their deaths.

"I teach them all the good I can, and recommend them to others from whom I think they will get some moral benefit. And the treasures that the wise men of old have left us in their writings I open and explore with my friends. If we come on any good thing, we extract it, and we set much store on being useful to one another." - Socrates
"In imitation of the method of the bee, I shall make my composition from those things which are conformable with the truth and from our enemies themselves gather the fruit of salvation. But I shall reject all that is worthless and falsely labeled as knowledge." - St. John the Damascene
