First of all it may be well to define the term we use. What is mysticism?
It deals largely with ourselves, and our own state and apprehension of the truth. It is occupied not with divine realities themselves, but with how we become conscious of those realities, and of the way they work out certain results in us.
The Word of God deals with the state of His saints. It throws light upon the progressive work of the Spirit in our souls. All this truth, which we speak of commonly as subjective, is of great importance, and we do well to maintain it, firmly holding it in its true connection with the great objective realities themselves, since every action of the Spirit within us subjectively is in strict accord with the objective reality by which He works.
Mysticism, however, does not preserve the Scriptural order and balance as between these two sides of truth. In its eyes the subjective side appears so great that the objective realities are largely obscured. We say largely because it does not deny God’s revelation in Christ, nor the reality of the work He accomplished for us, nor that which He will yet accomplish for us at His coming again. It admits these things theologically, and then relegates them into the background of the picture in order that the foreground may be the more effectually occupied with the Spirit’s work within us. Consequently to the mystic this subjective side of things becomes the only thing worth consideration. The consciousness of the thing becomes in his thoughts virtually the thing itself. He talks therefore continually about his consciousness, his apprehension, his experiences; which is only another way of saying he is wrapped up in himself. He speaks of Christ, but views Him as the One who produces these impressions.
Nor is this all. If people could be found marked only by these characteristics, it is doubtful if the term “mystics” could be properly applied to them. The essence of mysticism lies in this, that the seat of authority is transferred in the mind of the mystic from the external ” Word of God” to the spiritual consciousness — the “spiritual man” — internal to themselves. Homage of quite an orthodox kind may be verbally rendered to the Scriptures, and yet they may be largely displaced. The spiritual conception of the mystic, who flatters himself that he is indeed a spiritual man, are all important to him. He soars above and beyond the Scripture. Its letter he disdains, even if he does not speak against it. It has little or no restraining effect upon the flights of his imagination. He quotes it of course, but only as supporting or illustrating or adorning his own conceptions of truth. His conceptions become the primary things on which the main emphasis must be laid. Scripture must be interpreted in the light of those conceptions, and its words become of secondary importance.
At the opposite pole to mysticism lies a cold orthodoxy devoid of power. It is sadly possible to insist correctly on all the great objective verities of the faith without much exercise of conscience as to a positive entrance upon these realities in the power of the Spirit of God. Truth may thus be stated and Scripture correctly expounded without the warmth of the love of the truth. In this frame of mind people seem to fear what is subjective and experimental in ministry as though it in some way robbed them of truth itself, instead of it being only calculated to divest them of an easy-going mental acceptance of truth and of the self- complacency which goes with it, and plunge them into genuine exercise of heart before God. In all this tendency there is something poor and shallow, and earnest souls are by it repelled.
Mysticism has about it an apparent profundity of thought and utterance. It promises a far greater depth of understanding, which is alluring, and especially to minds of a certain contemplative type, fundamentally disposed towards introspection and self-occupation. Though the present age is one of turmoil and shallow reasoning, mysticism still makes its voice heard, and by its very contrast offers certain attractions. Hence we believe a few words of warning may be profitable, especially, as its ultimate tendencies have always been towards not only indefiniteness of doctrine and statement, but to the maintenance of teachings quite foreign to and astray from the Word of God. As before, so again it has led to grave and fundamental error.
