Luke 12:33

Sell what ye have, and give alms. This is a counsel, not a precept, as Pelagius would have it, who said that all Christians ought to be poor, from the precept of Christ. This is shewn by the words of Christ (Mat 19:21), "If thou wouldst be perfect, go sell that thou hast and give to the poor." That you may study evangelical perfection, sell what you possess and give the price to the poor, that you may follow Me who am poor in spirit in a like poverty, and with me despise earthly riches, that so you may obtain heavenly ones. Do this with the end that you may show yourselves not anxious for food and raiment, but that you depend solely on God, and look to Him for all those needs of life which He Himself has promised to all who seek His kingdom. For this reason the first Christians, following the counsel of Christ, sold all that they had and laid the price at the feet of the apostles, that they might distribute them among the poor believers (Acts ii 3, 4). So Bede: "Fear not that you will lack the needful things of life, but rather sell what you possess for alms. This is done worthily when he who lives by the labour of his hands, despises all things, and gives alms."

Provide yourselves bags which wax not old. Wax not old, and from which, therefore, the coin of spiritual alms cannot drop out and be lost, as the money of the world often falls from the old and worn-out purses of the rich. The purses that wax not old are the bosoms of the poor, and more especially the mind and memory of God, in which He keeps as in a purse your alms and good works, that He may return you the most ample rewards for them in the day of judgment. This He Himself explains, adding, a treasure in the heavens that faileth not, where no thief draweth near, neither moth destroyeth. From this Chrysologus rightly concludes, "What have they to do with the earth who possess heaven what with human affairs who have gained divine ones unless, perhaps, they find pleasure in lamentations, choose labours, delight in dangers, love the most cruel deaths, and find the evil things that are brought upon them more pleasing than the good ones?"
