Luke 10:25

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.

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 as 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 to him, What is written in the law? how read you?

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, showing 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, you shall love the Lord your God with all your heart, and with all your soul, and with all your strength, and, with all your mind.

By saying, with all your 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 fullness; so also the soul, whatever love it has wasted upon things unlawful, has so much lessened its love to God.

Now 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.

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 your strength.

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.

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. 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 neighbor. Hence it follows, And your neighbor as yourself. 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.

Yet observe how, almost to the same extent of obedience he requires the performance of each command. For of God he says, with all your heart. Of our neighbor, as yourself: Which if it were diligently kept, there would be neither slave nor free man, neither conqueror nor conquered, (or rasher, 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 fervor of love; so surpassing all things is the constancy of love.

But since it is said, You shall love your neighbor as yourself, how is he merciful in taking compassion upon another, who still, by unrighteous living, is unmerciful to himself?

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, you have answered right: this do, and you shall live.

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, You shall love the Lord your God; and from Leviticus, You shall love your neighbor as yourself: But these things were spoken against the flowers 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?

The fact that certain rich women clave to Christ, “which ministered unto Him of their substance,” amongst whom was the wife of the king’s steward, is a subject of prophecy. By Isaiah the Lord called these wealthy ladies, “Rise up, ye women that are at ease, and hear my voice”, that He might prove them first as disciples, and then as assistants and helpers: “Daughters, hear my words in hope; this day of the year cherish the memory of, in labour with hope.” For it was “in labour” that they followed Him, and “with hope” did they minister to Him. On the subject of parables , let it suffice that it has been once for all shown that this kind of language was with equal distinctness promised by the Creator. …

But whenever a dispute arises about the nativity, all who reject it as creating a presumption in favour of the reality of Christ’s flesh, wilfully deny that God Himself was born, on the ground that He asked, “Who is my mother, and who are my brethren?” Let, therefore, Apelles hear what was our answer to Marcion in that little work, in which we challenged his own (favourite) gospel to the proof, even that the material circumstances of that remark (of the Lord’s) should be considered. …

142. Luke, on the other hand, not indeed in this order, but in a widely different connection, introduces something which resembles this. But whether in that passage he is actually recording this same incident, or whether the person with whom the Lord [is represented to have] dealt in a similar manner there on the subject of those two commandments is quite another individual, is altogether uncertain. At the same time, it may appear right to regard the person who is introduced by Luke as a different individual from the one before us here, not only on the ground of the remarkable divergence in the order of narration, but also because he is there reported to have replied to a question which was addressed to him by the Lord, and in that reply to have himself mentioned those two precepts. …

But just as when we see a child crying, and pertinaciously wishing to get something from us that is not expedient for him, we hide the thing, and show him our empty hands, and say, “See, we have it not:” the like has Christ here done with the Apostles. But as the child, even when we show him [our empty hands], persists with his crying, conscious he has been deceived, and then we leave him, and depart, saying, “Such an one calls me:” and we give him something else instead, in order to divert him from his desire, telling him it is a much finer thing than the other, and then hasten away; in like manner Christ acted. The disciples asked to have something, and He said He had it not. And on the first occasion he frightened them. …
