Few words have been used with a greater latitude of meaning than mysticism. It is here to be taken in a sense antithetical to speculation. Speculation is a process of thought; mysticism is a matter of feeling. The one assumes that the thinking faculty is that by which we attain the knowledge of truth. The other distrusting reason teaches that feelings alone are to be relied upon, at least in the sphere of religion.
Divine revelation appeals to preparation in the human spirit, which it explains and accounts for: first, the instinctive (intuitive) and indestructible sense of dependence on a First Cause; secondly, the consciousness of responsibility to a Supreme Authority; and third, the union of these in the deep desire to know and have fellowship with the Source and End of life.
Every science has two factors: facts and ideas, or facts and the mind. Science is more than knowledge. Knowledge is the persuasion of what is true on adequate evidence. If theology is a science, it must include something more than mere knowledge of facts. It must embrace an exhibition of the internal relation of those facts, one to another and each to all. It must be able to show that if one is admitted, others cannot be denied.
Jesus has confirmed and supplemented Natural Theology, or that which is independent of supernatural revelation. He has consummated the preliminary disclosures of His own earlier dispensations. He has discredited and condemned all teachers and teaching that reject His authority.
Christian Theology is the science of God and Divine things, based upon the revelation made to mankind in Jesus Christ and variously systematized within the Christian Church.
Theology is mainly concerned with the things of God as they are related to man and his [journey]. This statement, divine things made known to man, implies the capacity in our nature to receive Divine truth.
