56. It may be supposed that the doctrine of genuine truth can be acquired by means of the spiritual sense of the Word which is obtained through a knowledge of correspondences. Doctrine, however, is not acquired by such means, but only illustrated and corroborated. For as was stated above in No. 26 no one comes into the spiritual sense of the Word by means of correspondences unless he is first in genuine truths from doctrine. If a man is not first in genuine truths, he may falsify the Word by means of some correspondences he may know, by connecting them together and explaining them to confirm what is firmly held in his mind from some principle which he has adopted. Moreover, the spiritual sense is not communicated to anyone except by the Lord alone; and He guards it as He guards heaven, for heaven is within it. It is important then that a man should study the Word in the sense of the Letter: from that sense only is doctrine derived.
