3. Finally, there follow other acts, too many to number, though there are twelve usually given, which result from gifts and beatitudes. These are called the fruits of the Holy Ghost, for they represent in that metaphorical sense the ultimate result of the gifts. They are the last and sweetest consequences of the sevenfold habits infused by the Spirit. Indeed, just as trees are grown in an orchard because of their fruits, and, therefore, just as it can be said that the fruit is, from the gardener's point of view, the purpose for which the tree is cultivated (for of the fruitless fig Our Lord asked why it cumbered the ground), so these fruits of the Holy Ghost (charity, joy, peace, patience, benignity, goodness, longanimity, mildness, faith, modesty, continency, chastity--Gal. 5.22) can be looked upon as the very purpose for which the gifts were given, that I might, by seeing a new blessedness in life's very troubles, begin to find joy and peace and patience and faith, where else I had found only sorrow. Endlessly could the list of these be extended, for St. Paul has chosen only a very few; but these that he names are what a man delights in when he has received the gifts, and has understood and valued the beatitudes. Sweetness is what they add to virtue, ease, comfort. I not only hunger and thirst after justice, but enjoy the very pain of the pursuit. KNOWLEDGE 1. This gift of God illumines and perfects the intelligence. The purpose of the gifts, it has been already explained, is to make the soul more alive to, and more appreciative of, the whispered instinct of God; not to create new faculties, but to increase the power of those already existing. My mind, then, has to be supernaturalized and refined to that pitch of perception which will enable it to grasp and to understand God's message. Now the mind itself works upon a great variety of subjects. It has whole worlds to conquer, planes of thought which are very clearly distinguishable; yet in its every activity it needs this divine refinement, so that in all four gifts are allotted to perform this complete enlightenment of the mind. Knowledge overcomes ignorance and is concerned with the facts, visible and sense-perceived, in creation; for by the council of the Vatican it is laid down as part of the deposit of faith that human reason can prove the existence of God altogether apart from the supernatural motives which grace supplies. The visible world is held to contain ample proofs which in themselves are adequate logically to convince human understanding of the existence of God. Individual reason may fail to satisfy itself. People may declare truthfully that they are not convinced; the Church insists only that it can be done.
