Nine Homilies of Hexaemeron

⁷ But let us return to the examination of the ingenious contrivances of creation. How many trees then arose, some to give us their fruits, others to roof our houses, others to build our ships, others to feed our fires! What a variety in the disposition of their several parts! And yet, how difficult is it to find the distinctive property of each of them, and to grasp the difference which separates them from other species. Some strike deep roots, others do not; some shoot straight up and have only one stem, others appear to love the earth and, from their root upwards, divide into several shoots. Those whose long branches stretch up afar into the air, have also deep roots which spread within a large circumference, a true foundation placed by nature to support the weight of the tree. What variety there is in bark! Some plants have smooth bark, others rough, some have only one layer, others several. What a marvellous thing! You may find in the youth and age of plants resemblances to those of man. Young and vigorous, their bark is distended; when they grow old, it is rough and wrinkled. Cut one, it sends forth new buds; the other remains henceforward sterile and as if struck with a mortal wound. But further, it has been observed that pines, cut down, or even submitted to the action of fire, are changed into a forest of oaks. We know besides that the industry of agriculturists remedies the natural defects of certain trees. Thus the sharp pomegranate and bitter almonds, if the trunk of the tree is pierced near the root to introduce into the middle of the pith a fat plug of pine, lose the acidity of their juice, and become delicious fruits. Let not the sinner then despair of himself, when he thinks, if agriculture can change the juices of plants, the efforts of the soul to arrive at virtue, can certainly triumph over all infirmities.

Now there is such a variety of fruits in fruit trees that it is beyond all expression; a variety not only in the fruits of trees of different families, but even in those of the same species, if it be true, as gardeners say, that the sex of a tree influences the character of its fruits. They distinguish male from female in palms; sometimes we see those which they call female lower their branches, as though with passionate desire, and invite the embraces of the male. Then, those who take care of these plants shake over these palms the fertilizing dust from the male palm-tree, the psen as they call it: the tree appears to share the pleasures of enjoyment; then it raises its branches, and its foliage resumes its usual form. The same is said of the fig tree. Some plant wild fig trees near cultivated fig trees, and there are others who, to remedy the weakness of the productive fig tree of our gardens, attach to the branches unripe figs and so retain the fruit which had already begun to drop and to be lost. What lesson does nature here give us? That we must often borrow, even from those who are strangers to the faith, a certain vigour to show forth good works. If you see outside the Church, in pagan life, or in the midst of a pernicious heresy, the example of virtue and fidelity to moral laws, redouble your efforts to resemble the productive fig tree, who by the side of the wild fig tree, gains strength, prevents the fruit from being shed, and nourishes it with more care.
