Spiritual knowledge is like a house built in the midst of secular and pagan knowledge, in which there is laid up, like a solid and well-secured chest, the knowledge of the inspired Scriptures and the inestimable riches they contain. Those who enter into the house will never at all be able to see those treasures unless this chest is opened for them. But it does not belong to human wisdom (cf. I Cor. 2:13) ever to be able to open it, so that the riches of the Spirit deposited in it remain unknown to all who are worldly.
