For the earth of itself bringeth forth fruit; first the blade, then the ear, afterwards the full corn in the ear. Arabic, Because the earth alone bringeth forth fruit; . . . afterwards the ear is filled, and when the fruit is perfect, then the sickle is applied, because it is harvest. Thus, in like manner, by the preaching of the Gospel, the faith of Christ and His Church grew by various degrees of increase.
Moraliter: Expositors adapt these three expressions, blade, ear, full corn, to a threefold increment of virtues and merits. For the earth of our heart germinates, first, the blade, when it conceives good desires; secondly, the ear, when it proceeds to earnest working; thirdly, the grain, when it brings the works of virtue to full maturity and perfection. Theophylact says, "The blade is the beginning of good; the ear is when we resist temptations; the fruit is perfect work."
Hear S. Gregory (Hom15 , in Ezek.), "To produce the blade is to hold the first tender beginning of good. Th...
To produce “the blade” is to hold the first tender beginning of good. The “blade” arrives at maturity when virtue conceived in the mind leads to advancement in good works. The “full corn” fructifies in “the ear” when virtue makes such great progress that it comes into its fullest possible expression.
And the cup His blood, if they do not call Himself the Son of the Creator of the world, that is, His Word, through whom the wood fructifies, and the fountains gush forth, and the earth gives "first the blade, then the ear, then the full corn in the ear."
Observe how the created order has advanced little by little toward fruitfulness. First comes the grain, and from the grain arises the shoot, and from the shoot emerges the shrub. From there the boughs and leaves gather strength, and the whole that we call a tree expands. Then follows the swelling of the germen, and from the germen bursts the flower, and from the flower the fruit opens. The fruit itself, primitive for a while, and unshapely, keeping the straight course of its development, is matured, little by little, to the full mellowness of its flavor. In just this way has righteousness grown in history. The proximate righteousness found in the created order is grounded in the holy God whose righteousness first emerged in a rudimentary stage as an undeveloped natural apprehension in the presence of the holy One. Then it advanced through the law and prophets to childhood. At long last through the gospel, God’s righteousness has been personally manifested with the vital energies of you...
First comes the grain, and from the grain arises the shoot, and from the shoot struggles out the shrub: thereafter boughs and leaves gather strength, and the whole that we call a tree expands: then follows the swelling of the germen, and from the germen bursts the flower, and from the flower the fruit opens: that fruit itself, rude for a while, and unshapely, little by little, keeping the straight course of its development, is trained to the mellowness of its flavour.
