BEDE . Our Lord had told His disciples above that their names were written in Heaven; from this it seems to me the lawyer took occasion of tempting our Lord, as it is said, And, behold, a certain lawyer stood up, and tempted him.
CYRIL OF ALEXANDRIA . For there were in fact certain men who then went about the whole country of the Jews bringing charges against Christ, and saying that He spoke of the commands of Moses as useless, and Himself introduced certain strange doctrines. A lawyer then, wishing to entrap Christ into saying something against Moses, comes and tempts Him, calling Him Master, though not bearing to be His disciple. And because our Lord was wont to speak to those who came to Him concerning eternal life, the lawyer adopts this kind of language. And since he tempted Him subtly, he receives no other answer than the command given by Moses; for it follows, He said unto him, What is written in the law? how readest thou?
AMBROSE . For he was one of those who think themselves skilled in the law, and who keep the letter of the law, while they know nothing of its spirit. From a part of the law itself our Lord proves them to be ignorant of the law, shewing that at the very first the law preached the Father and the Son, and announced the sacraments of the Lord’s Incarnation; for it follows, And he answering said, Thou shall love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind.
BASIL . (in Ps. 44.) By saying, with all thy mind, he does not admit of any division of love to other things, for whatever love you cast on lower things necessarily takes away from the whole. For as a vessel full of liquid, whatever flows therefrom must so much diminish its fulness; so also the soul, whatever love it has wasted upon things unlawful, has so much lessened its love to God.
GREGORY OF NYSSA . (de Hom. Opif. c. 8.) the soul is divided into three faculties; one merely of growth and vegetation, such as is found in plants; another which relates to the senses, which is preserved in the nature of irrational animals; but the perfect faculty of the soul is that of reason, which is seen in human nature. By saying then the heart, He signified the bodily substance, that is, the vegetative; by the soul the middle, or the sensitive; but by saying the mind, the higher nature, that is, the intellectual or reflective faculty.
THEOPHYLACT . We must hereby understand that it becomes us to submit every power of the soul to the divine love, and that resolutely, not slackly. Hence it is added, And with all thy strength.
MAXIMUS . To this end then the law commanded a threefold love to God, that it might pluck us away from the threefold fashion of the world, as touching possessions, glory, and pleasure, wherein also Christ was tempted.
BASIL . (Reg. fus. ad int. 2.) But if any one ask how the love of God is to be obtained, we are sure that the love of God cannot be taught. For neither did we learn to rejoice in the presence of light, or to embrace life, or to love our parents and children; much less were we taught the love of God, but a certain seminal principle was implanted in us, which has within itself the cause, that man clings to God; which principle the teaching of the divine commands is wont to cultivate diligently, to foster watchfully, and to carry on to the perfection of divine grace. For naturally we love good; we love also what is our own, and akin to us; we likewise of our own accord pour forth all our affections on our benefactors. If then God is good, but all things desire that good, which is wrought voluntarily, He is by nature inherent in us, and although from His goodness we are far from knowing Him, yet from the very fact that we proceeded forth from Him, we are bound to love Him with exceeding love, as in truth akin to us; He is likewise also a greater benefactor than all whom by nature we love here. (ad int 3.). And again. The love of God then is the first and chief command, but the second, as filling up the first and filled up by it, bids us to love our neighbour. Hence it follows, And thy neighbour as thyself. But we have an instinct given us by God to perform this command, as who does not know that man is a kind and social animal? For nothing belongs so much to our nature as to communicate with one another, and mutually to need and love our relations. Of those things then of which in the first place He gave us the seed, He afterwards requires the fruits.
CHRYSOSTOM . (Hom. 32. in 1 Cor.) Yet observe how, almost to the same extent of obedience he requires the performance of each command, For of God he says, with all thy heart. Of our neighbour, as thyself. Which if it were diligently kept, there would be neither slave nor free man, neither conqueror nor conquered, (or rather, neither prince nor subject,) rich nor poor, nor would the devil be even known, for the chaff would rather stand the touch of fire than the devil the fervour of love; so surpassing all things is the constancy of love.
GREGORY . (19. Moral. c. 14.) But since it is said, Thou shalt love thy neighbour as thyself, how is he merciful in taking compassion upon another, who still, by unrighteous living, is unmerciful to himself?
CYRIL OF ALEXANDRIA . When the lawyer had answered the things contained in the law, Christ, to whom all things were known, cuts to pieces his crafty nets. For it follows, And he said to him, Thou hast answered right: this do, and thou shalt live.
ORIGEN . From these words it is undoubtingly gathered, that the life which is preached according to God the Creator of the world, and the Scriptures given by Him, is life everlasting. For the Lord Himself bears testimony to the passage from Deuteronomy, Thou shalt love the Lord thy God; (Deut. 6:5.) and from Leviticus, Thou shalt love thy neighbour as thyself. (Lev. 19:18.) But these things were spoken against the followers of Valentinus, Basil, and Marcion. For what else did he wish us to do in seeking eternal life, but what is contained in the Law and the Prophets?
10:29–37
29. But he, willing to justify himself, said unto Jesus, And who is my neighbour?
30. And Jesus answering said, A certain man went down from Jerusalem to Jericho, and fell among thieves, which stripped him of his raiment, and wounded him, and departed, leaving him half dead.
31. And by chance there came down a certain Priest that way: and when he saw him, he passed by on the other side.
32. And likewise a Levite, when he was at the place, came and looked on him, and passed by on the other side.
33. But a certain Samaritan, as he journeyed, came where he was; and when he saw him, he had compassion on him,
34. And went to him, and bound up his wounds, pouring in oil and wine, and set him on his own beast, and brought him to an inn, and took care of him.
35. And on the morrow when he departed, he took out two pence, and gave them to the host, and said unto him, Take care of him; and whatsoever thou spendest more, when I come again, I will repay thee.
36. Which now of these three, thinkest thou, was neighbour unto him that fell among the thieves?
37. And he said, He that shewed mercy on him. Then said Jesus unto him, Go, and do thou likewise.
CYRIL OF ALEXANDRIA . The lawyer, when praised by our Saviour for having answered right, breaks forth into pride, thinking that he had no neighbour, as though there was no one to be compared to him in righteousness. Hence it is said, But he willing to justify himself said unto Jesus, And who is my neighbour? For somehow first one sin and then another takes him captive. From the cunning with which he sought to tempt Christ, ho falls into pride. But here when asking, who is my neighbour, he proves himself to be devoid of love for his neighbour, since he did not consider any one to be his neighbour, and consequently of the love of God; for he who loves not his brother whom he sees, cannot love God whom he does not see. (1 John 4:20.)
AMBROSE . He answered that he knew not his neighbour, because he believed not on Christ, and he who knows not Christ knows not the law, for being ignorant of the truth, how can he know the law which makes known the truth?
THEOPHYLACT . Now our Saviour defines a neighbour not in respect of actions or honour, but of nature; as if He says, Think not that because thou art righteous thou hast no neighbour, for all who partake of the same nature are thy neighbours. Be thou also their neighbour, not in place, but in affection and solicitude for them. And in addition to this, he brings forward the Samaritan as an example. As it follows, And Jesus answering him said, A certain man went down, &c.
