19 Then, again, as regards the parable of the sower in the Gospel, we read that the good ground brought forth fruit, some a hundred fold, some sixty fold, and some thirty fold; and, on the other hand, that the bad ground admitted of three degrees of sterility: but Jovinianus makes only two classes, the good soil and the bad. And as in one Gospel our Lord promises the Apostles a hundred fold, in another seven fold, for leaving children and wives, and in the world to come life eternal; and the seven and the hundred mean the same thing: so, too, in the passage before us, the numbers describing the fertility of the soil need not create any difficulty, particularly when the Evangelist Mark gives the inverse order, thirty, sixty, and a hundred. The Lord says, “He that eats my flesh and drinks my blood abides in me, and I in him.” As, then, there are not varying degrees of Christ's presence in us, so neither are there degrees of our abiding in Christ. “Every one that loves me will keep my word: and my Father will love him, and we will come unto him, and make our abode with him.” He that is righteous, loves Christ: and if a man thus loves, the Father and the Son come to him, and make their abode with him. Now I suppose that when the guest is such as this the host cannot possibly lack anything. And if our Lord says, “In my Father's house are many mansions,” His meaning is not that there are different mansions in the kingdom of heaven, but He indicates the number of Churches in the whole world, for though the Church be seven-fold she is but one. “I go,” He says, “to prepare a place for you,” not places. If this promise is peculiar to the twelve apostles, then Paul is shut out from that place, and the chosen vessel will be thought superfluous and unworthy. John and James, because they asked more than the others, did not obtain it; and yet their dignity is not diminished, because they were equal to the rest of the apostles. “Do you not know that your bodies are a temple of the Holy Ghost?” A temple, He says, not temples, in order to show that God dwells in all alike. “Neither for these only do I pray, but for them also that believe in me through their word; as thou, Father, in me, and I in you, are one, so they may be all one in us. And the glory which you have given me I have given unto them. I have loved them, as you have loved me. And as we are Father, Son, and Holy Ghost, one God, so may they be one people in themselves, that is, like dear children, partakers of the divine nature.” Call the Church what you will, bride, sister, mother, her assembly is but one and never lacks husband, brother, or son. Her faith is one, and she is not defiled by variety of doctrine, nor divided by heresies. She continues a virgin. Whithersoever the Lamb goes, she follows Him: she alone knows the Song of Christ.
20. “If you tell me,” says he, “that one star differs from another star in glory, I reply, that one star does differ from another star; that is, spiritual persons differ from carnal. We love all the members alike, and do not prefer the eye to the finger, nor the finger to the ear: but the loss of any one is attended by the sorrow of all the rest. We all alike come into this world, and we all alike depart from it. There is one Adam of the earth, and another from heaven. The earthly Adam is on the left hand, and will perish: the heavenly Adam is on the right hand, and will be saved. He who says to his brother, ' thou fool,' and ' raca,' will be in danger of Gehenna. And the murderer and the adulterer will likewise be sent into Gehenna. In times of persecution some are burnt, some strangled, some beheaded, some flee, or die within the walls of a prison: the struggle varies in kind, but the victors' crown is one. No difference was made between the son who had never left his father, and his brother who was welcomed as a returning penitent. To the labourers of the first hour, the third, the sixth, the ninth, and the eleventh, the same reward of a penny was given, and what may perhaps seem still more strange to you, the first to receive the reward were they who had toiled least in the vineyard.”
