Patristic Wisdom: Looking to the Fifteenth Sunday after Pentecost

At that time the disciples came to Jesus, saying, “Who then is greatest in the kingdom of heaven?” Then Jesus called a little child to Him, set him in the midst of them, and said, “Assuredly, I say to you, unless you are converted and become as little children, you will by no means enter the kingdom of heaven. Therefore whoever humbles himself as this little child is the greatest in the kingdom of heaven. Whoever receives one little child like this in My name receives Me. But whoever causes one of these little ones who believe in Me to sin, it would be better for him if a millstone were hung around his neck, and he were drowned in the depth of the sea. Woe to the world because of offenses! For offenses must come, but woe to that man by whom the offense comes! “If your hand or foot causes you to sin, cut it off and cast it from you. It is better for you to enter into life lame or maimed, rather than having two hands or two feet, to be cast into the everlasting fire. And if your eye causes you to sin, pluck it out and cast it from you. It is better for you to enter into life with one eye, rather than having two eyes, to be cast into hell fire. Take heed that you do not despise one of these little ones, for I say to you that in heaven their angels always see the face of My Father who is in heaven. For the Son of Man has come to save that which was lost. What do you think? If a man has a hundred sheep, and one of them goes astray, does he not leave the ninety-nine and go to the mountains to seek the one that is straying? And if he should find it, assuredly, I say to you, he rejoices more over that sheep than over the ninety-nine that did not go astray. Even so it is not the will of your Father who is in heaven that one of these little ones should perish. Moreover if your brother sins against you, go and tell him his fault between you and him alone. If he hears you, you have gained your brother. But if he will not hear, take with you one or two more, that ‘by the mouth of two or three witnesses every word may be established.’ And if he refuses to hear them, tell it to the church. But if he refuses even to hear the church, let him be to you like a heathen and a tax collector. Assuredly, I say to you, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven. Again I say to you that if two of you agree on earth concerning anything that they ask, it will be done for them by My Father in heaven. For where two or three are gathered together in My name, I am there in the midst of them.” (Matthew 18:1–20)

Every one that gives his adherence to Jesus as the Son of God according to the true history concerning Him, and by deeds done according to the Gospel, is on the way to living the life which is according to virtue, is converted and is on the way towards becoming as the little children; and it is impossible for him not to enter into the kingdom of heaven. There are, indeed, many such; but not all, who are converted with a view to becoming like the little children, have reached the point of being made like unto little children; but each wants so much of the likeness to the little children, as he falls short of the disposition of little children towards the passions, of which we have spoken. In the whole multitude, then, of believers, are also those who, having been, as it were, just converted in regard to their becoming as the little children, at the very point of their conversion that they may become as the little children, are called little; and those of them, who are converted that they may become as the little children, but fall far short of having truly become as the little children, are capable of being caused to stumble; each of whom falls so far short of the likeness to them, as he falls short of the disposition of children towards the passions, of which we have spoken, to whom we ought not to give occasions of stumbling-block; but, if it be otherwise, he who has caused him to stumble will require, as contributing towards his cure, to have “an ass’s millstone hanged about his neck, and be sunk into the depths of the sea.” For, in this way, when he has paid the due penalty in the sea, where is “the dragon which God formed to play in it,” and, so far as is expedient for the end in view, has been punished and undergone suffering, he shall then have his part in those troubles which belong to the depths of the sea, which he endured when he was dragged down by the ass’s millstone. For there are also differences of millstones, so that one of them may be, so to call it, the millstone of a man, and another that of an ass; and that is human, about which it is written, “Two women shall be grinding at the mill; one is taken and one is left;” but the millstone of the ass is that which shall be put round him who has given occasion of stumbling-block. But some one might say—I know not whether he would speak soundly or erroneously—that the ass’s millstone is the heavy body of the wicked man, which is sunken downwards, and which he will receive at the resurrection that he may be sunk in the abyss which is called the depth of the sea, where “is the dragon which God formed to play therein.” But another will refer the creating of a stumbling-block to one of the little ones to the powers that are unseen by men; for from these arise many stumbling-blocks to the little ones pointed out by Jesus. But when they cause to stumble one of the little ones pointed out by Jesus, who are believers in Him, he shall assume an ass’s millstone, the corruptible body which presses heavily on the soul, which is itself hung from the neck, which is dragged down to the affairs in this life, that by means of these their conceit may be taken away, and having paid the penalty, they shall come, through means of the ass’s millstone, to the condition expedient for them.
