Have you read any of the writings of true mystics, peter? Sermons on The Song of Songs? Dark Night of the Soul/Saint John of the Cross? Bernard Clairvaux? Bother Lawrence? The Goad of Love/Walter Hilton? These are just a few. You will not find doctrinal arguments in their writings because they have moved beyond that into living a crucified life. Their longing is for holiness of heart before God. They've gone beyond what most of us have. They've left it behind. They want holiness so they can praise God WORTHILY. They have seen that there is something beyond "being saved." They don't believe Gods purpose was to save them from hell. They believe His purpose in saving them was to make them more like Christ. You won't find them at the places a lot of christians go. They live separated from the world because they have died to it. You won't find them at a football game, screaming in delight at touchdowns. You won't find them hiring designers to make their home look beautiful. Not that these things are something they would rant and rave and condemn others over. You just won't find THEM there. They won't look or talk like all of the other christians you see. They will look very odd to others. They won't defend themselves. They won't argue over doctrine but they can help those who have begun to die to self. The very church they have been in has often treated them harshly and not understood them. The only ones who understand them are others who have begun on this way of the crucified life. You won't find them defending voraciously any man or teacher, but you will find them listening and taking away only what parts of what another man says that will help them to die more so they can please God more. They understand that to choose this road of self-abegnation is hard and painful. They assume that anyone who might be even a little interested in what they have to say has already begun in this way. They would prefer that theological doctors and debaters not even read what they have written because they know it won't help them or anyone else for them to read it. In fact, anyone not having begun on this way will become bored very quickly by their writing. If something they read helps them to die more, they rejoice in it and thank God for giving the book or sermon to them. I can give you a more extensive list of writings that are considered mystical if you want to see that what I am saying is true. You won't find them rejoicing in being righteous or holy. You will find them rejoicing at great difficulties and struggles within themselves because they have seen it makes them more like their Lord. They have understood that the path to growing holiness is death to their wants, desires, defense of self, personal comfort, possessions, etc. Self fulfillment to them is contrary to what the world thinks of as self fulfillment. Self fulfillment to them is dying.
Wherefore if ye be dead with Christ from the rudiments of the world, why, as though living in the world, are ye subject to ordinances, (Touch not; taste not; handle not; Which all are to perish with the using after the commandments and doctrines of men? Which things have indeed a shew of wisdom in will worship, and humility, and neglecting of the body; not in any honour to the satisfying of the flesh. Colossians 2:20-23
