3. And lastly, things that are contrary hinder one another. But the active and the contemplative life are contrary to one another; for the active life is occupied with many things, whereas the contemplative life dwells upon one object of contemplation; they are, then, in opposite camps. But all these arguments insist upon the occupation with external affairs which is but one feature in the active life, not upon its other feature--namely, its power to repress the passions. * * * * * _Cajetan: But the five foolish virgins, having taken their lamps, did not take oil with them. But the wise took oil in their vessels with the lamps._[478] By this oil is signified testimony to a man's goodness or love of God. For there is this difference between people who perform good works, that the only testimony which some men have to their goodness is without--namely, in the works themselves; within, however, they do not feel that they love God with their whole heart, that they repent of their sins because they are hateful to God, or that they love their neighbour for God's sake. But there are others who so perform good works that both their works that shine before men bear witness without to the good soul within, and also within their own conscience the Holy Spirit Himself testifies to their spirit that they are the sons of God; for such men feel that they love God with their whole heart, that they repent of their sins for God's sake, and that they love their neighbour and themselves for God's sake: in brief, they feel that God is the sole reason why they love, why they hope, fear, rejoice, or are sad: in a word, why they work both within and without: this is to have oil in one's own vessels (_On S. Matt._ xxv. 3, 4). _S. Augustine:_ See the life that Mary chose! Yet was she but a type of that life, she as yet possessed it not. For there are two kinds of life: one means delight; the other means a burden. And the burdensome one is toilsome, while the delightsome one is pleasurable. But enter thou within; seek not that delight without, lest ye swell with it and find yourself unable to enter by the narrow gate! See how Mary saw the Lord in the Flesh and heard the Lord by the voice of the Flesh--as ye have heard when the Epistle to the Hebrews has been read--as it were through a veil. (_A new and living way which He hath dedicated to us through the veil, that is to say, His Flesh_.[479]) But when we shall see Him face to Face there will be no "veil." Mary, then, sat--that is, she rested from toil--and she listened and she praised; but Martha was anxious about much serving. And the Lord said to her: _Martha, Martha, thou art careful and art troubled about many things; but one thing is necessary[480]_ (_Sermon_, CCLVI., v. 6).
