Nicodemus said unto him, How can a man be born when he is old? can he enter the second time into his mother's womb, and be born?

John Chrysostom
AD 407
Callest thou Him Master, do you say that He is come from God, and yet do you not receive His words, but usest to your Teacher a manner of speaking which expresses much perplexity? For the How, is the doubting question of those who have no strong belief, but who are yet of the earth. Therefore Sarah laughed when she had said, How? And many others having asked this question, have fallen from the faith.
3. And thus heretics continue in their heresy, because they frequently make this enquiry, saying, some of them, How was He begotten? others, How was He made flesh? and subjecting that Infinite Essence to the weakness of their own reasonings. Knowing which, we ought to avoid this unseasonable curiosity, for they who search into these matters shall, without learning the How, fall away from the right faith. On this account Nicodemus, being in doubt, enquires the manner in which this can be, (for he understood that the words spoken referred to himself,) is confused, and dizzy, and in perplexity, having come as to a man, and hearing more than man's words, and such as no one ever yet had heard; and for a while he rouses himself at the sublimity of the sayings, but yet is in darkness, and unstable, borne about in every direction, and continually falling away from the faith. And therefore he perseveres in proving the impossibility, so as to provoke Him to clearer teaching.
Can a man, he says, enter into his mother's womb, and be born?
Do you see how when one commits spiritual things to his own reasonings, he speaks ridiculously, seems to be trifling, or to be drunken, when he pries into what has been said beyond what seems good to God, and admits not the submission of faith? Nicodemus heard of the spiritual Birth, yet perceived it not as spiritual, but dragged down the words to the lowness of the flesh, and made a doctrine so great and high depend upon physical consequence. And so he invents frivolities, and ridiculous difficulties. Wherefore Paul said, The natural man receives not the things of the Spirit. 1 Corinthians 2:14 Yet even in this he preserved his reverence for Christ, for he did not mock at what had been said, but, deeming it impossible, held his peace. There were two difficulties; a Birth of this kind, and the Kingdom; for neither had the name of the Kingdom ever been heard among the Jews, nor of a Birth like this. But he stops for a while at the first, which most astonished his mind.
Let us then, knowing this, not enquire into things relating to God by reasoning, nor bring heavenly matters under the rule of earthly consequences, nor subject them to the necessity of nature; but let us think of all reverently, believing as the Scriptures have said; for the busy and curious person gains nothing, and besides not finding what he seeks, shall suffer extreme punishment. You have heard, that (the Father) begot (the Son): believe what you have heard; but do ask not, How, and so take away the Generation; to do so would be extreme folly. For if this man, because, on hearing of a Generation, not that ineffable Generation, but this which is by grace, he conceived nothing great concerning it, but human and earthly thoughts, was therefore darkened and in doubt, what punishment must they deserve, who are busy and curious about that most awful Generation, which transcends all reason and intellect? For nothing causes such dizziness as human reasoning, all whose words are of earth, and which cannot endure to be enlightened from above. Earthly reasonings are full of mud, and therefore need we streams from heaven, that when the mud has settled, the clearer portion may rise and mingle with the heavenly lessons; and this comes to pass, when we present an honest soul and an upright life. For certainly it is possible for the intellect to be darkened, not only by unseasonable curiosity, but also by corrupt manners; wherefore Paul has said to the Corinthians, I have fed you with milk, and not with meat; for hitherto you were not able to bear it, neither yet now are you able, for you are yet carnal; for whereas there is among you envying, and strife, and divisions, are you not carnal? 1 Corinthians 3:2 And also in the Epistle to the Hebrews, and in many places, one may see Paul asserting that this is the cause of evil doctrines; for that the soul possessed by passions cannot behold anything great or noble, but as if darkened by a sort of film suffers most grievous dimsightedness.
Let us then cleanse ourselves, let us kindle the light of knowledge, let us not sow among thorns. What the thorns are, you know, though we tell you not; for often you have heard Christ call the cares of this present life, and the deceitfulness of riches, by this name. Matthew 13:22 And with reason. For as thorns are unfruitful, so are these things; as thorns tear those that handle them, so do these passions; as thorns are readily caught by the fire, and hateful by the husbandman, so too are the things of the world; as in thorns, wild beasts, and snakes, and scorpions hide themselves, so do they in the deceitfulness of riches. But let us kindle the fire of the Spirit, that we may consume the thorns, and drive away the beasts, and make the field clear for the husbandman; and after cleansing it, let us water it with the streams of the Spirit, let us plant the fruitful olive, that most kindly of trees, the evergreen, the light-giving, the nutritious, the wholesome. All these qualities has almsgiving, which is, as it were, a seal on those that possess it. This plant not even death when it comes causes to wither, but ever it stands enlightening the mind, feeding the sinews of the soul, and rendering its strength mightier. And if we constantly possess it, we shall be able with confidence to behold the Bridegroom, and to enter into the bridal chamber; to which may we all attain, through the grace and lovingkindness of our Lord Jesus Christ, with whom to the Father and the Holy Ghost be glory, for ever and ever. Amen.
