“[T]rue Christian theology . . . does not present God to us in His majesty, as Moses and other teachings do, but Christ born of the Virgin as our Mediator and High Priest. Therefore when we are embattled against the Law, sin, and death in the presence of God, nothing is more dangerous than to stray into heaven with our idle speculations, there to investigate God in His incomprehensible power, wisdom, and majesty, to ask how He created the world and how He governs it. If you attempt to comprehend God this way and want to make atonement to Him apart from Christ the Mediator, making your works, fasts, cowl, and tonsure the mediation between Him and yourself, you will inevitably fall, as Lucifer did, and in horrible despair lose God and everything. For as in His own nature God is immense, incomprehensible, and infinite, so to man’s nature He is intolerable. Therefore if you want to be safe and out of danger to your conscience and your salvation, put a check on your speculative spirit. Take hold of God as Scripture instructs you: ‘Since, in wisdom, the world did not know God through wisdom, it pleased God through the folly of what we preach to save those who believe. We preach Christ crucified, a stumbling block to Jews and folly to Gentiles, but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God.’ Therefore begin where Christ began — in the Virgin’s womb, in the manger, and at His mother’s breasts. For this purpose He came down, was born, lived among men, suffered, was crucified, and died, so that in every possible way He might present Himself to our sight. He wanted us to fix the gaze of our hearts upon Himself and thus to prevent us from clambering into heaven and speculating about the Divine Majesty.
“Therefore when you consider the doctrine of justification and wonder how or where or in what condition to find a God who justifies or accepts sinners, then you must know that there is no other God than this Man Jesus Christ. Take hold of Him; cling to Him with all your heart, and spurn all speculation about the Divine Majesty; for whoever investigates the majesty of God will be consumed by His glory. I know from experience what I am talking about. . . . Christ Himself says: ‘I am the Way, and the Truth, and the Life; no one comes to the Father, but by Me.’ Outside Christ, the Way, therefore, you will find no other way to the Father; you will find only wandering, not truth, but hypocrisy and lies, not life, but eternal death. Take note, therefore, in the doctrine of justification or grace that when we all must struggle with the Law, sin, death, and the devil, we must look at no other God than this incarnate and human God.”
