This last principle needs a little explication. Not only because Philosophy is condemned for vain, but because it is superfluous among inferior Christians, and impossible, as some think, unto them. We must distinguish therefore of philosophy and of Christians also. Some philosophy, as Saint Paul says, is vain, but then it is vain philosophy. But there is also a Divine Philosophy, of which no books in the world are more full than his own. That we are naturally the Sons of God (I speak of primitive and upright nature,) that the Son of God is the first beginning of every creature, that we are to be changed from glory to glory into the same Image, that we are spiritual Kings, that Christ is the express Image of His Father's person, that by Him all things are made whether they are visible or invisible, is the highest Philosophy in the world; and so is it also to treat, as he does, of the nature of virtues and Divine Laws. Yet no man, I suppose, will account these superfluous, or vain, for in the right knowledge of these Eternal Life consisteth. And till we see into the beauty and blessedness of God's Laws, the glory of His works, the excellency of our soul, &c. we are but children of darkness, at least but ignorant and imperfect: neither able to rejoice in God as we ought, nor to live in communion with Him. Rather we should remember that Jesus Christ is the Wisdom of the Father, and that since our life is hid with Christ in God, we should spend our days in studying Wisdom, that we might be like unto Him:that the treasures of Heaven are the treasures of Wisdom, and that they are hid in Christ. As it is written, In Him are hid all the treasures of Wisdom and Knowledge.
