161. Hence, God himself condescends to the low plane of our understanding and presents himself to us with childlike simplicity in representations, as in a guise, so that he may be made known to us in some way. Thus the Holy Spirit appeared in the form of a dove; not because he is a dove, but in this crude form he desired to be recognized, received and worshiped, for it was really the Holy Spirit. No one, to be sure, will say that the same passage defines God as a voice speaking from heaven, yet under this crude image, a human voice from heaven, he was received and worshiped. 162. When Scripture thus ascribes to God human form, voice, actions and state of mind, it is intended as an aid only for the uncultivated and feeble; we who are great and learned and of discernment in reference to Scripture, should likewise lay hold of these representations, because God has put them forth and revealed himself to us through them. The angels likewise, appear in human form, though it is certain that they are only spirits; spirits we cannot recognize when they present themselves as such, but likenesses we do recognize. 163. This is the simplest way of treating such passages, for the nature of God we cannot define; what he is not we can well define--he is not a voice, a dove, water, bread, wine. And yet in these visible forms he presents himself to us and deals with us. These forms he shows to us that we should not become wandering and unsettled spirits which dispute concerning God, but are completely ignorant concerning him, since in his unveiled majesty he can not be apprehended. He sees it to be impossible for us to know him in his own nature. For he lives, as the Scripture says in 1 Timothy 6, 16, in an inaccessible light, and what we can apprehend and understand he has declared. They who abide in these things will truly lay hold of him, while those who vaunt and follow visions, revelations and illuminations will either be overwhelmed by his majesty or remain in densest ignorance of God. 164. Thus the Jews also had their representations in which God manifested himself to them, as the mercy-seat, the ark of the covenant, the tabernacle, the pillars of smoke and fire. God says in Exodus 33, 20, "Man shall not see me and live," therefore he gives a representation of himself in which he so manifests himself to us that we may lay hold of him. In the new covenant we have Baptism, the Lord's Supper, absolution and the ministry of the Word.
