Jesus was speaking to the Jєωs who were finding fault with what He did, that is, He healed a man on the sabbath. He was not speaking of anyone's presentation or looks. You can't just drag out scripture and make say what you want it to say.

If you ever think that Our Lord's wisdom and a Saint's wisdom are contradicting each other, please consult a Traditional Catholic Priest.  The writings of the saints should complement the words of Our Lord, those saints and their writings have been carefully reviewed by truly great minds.

Ver. 24.—Judge not according to appearance, but judge righteous judgment. He charges the Jєωs with acceptance of persons, in acquitting Moses, or rather themselves, in a like matter, but accusing and condemning Jesus. Ye accuse Me as a Sabbath-breaker only for healing a sick man by my divine power, whereas ye think it lawful by the law of Moses to circuмcise and wound a child, to heal his wound by applying plasters, and to staunch the blood, which is much more tedious, painful and horrible. And this is because ye judge not according to the truth of things, but according to the dignity of the persons. For Me ye contemn as vile, poor and hated; but ye set up yourselves with Moses as the chiefs and teachers of the people. For were ye to judge according to our doings, ye ought to acquit Me as well as Moses and yourselves; or if ye condemn Me, ye should condemn both Moses and yourselves. For I healed the man on the Sabbath, but ye with Moses on the very same day first wound and afterwards heal the child. And my object was even more holy, because I did it only for the glory of God, to show that I was the Messiah. So say S. Augustine, S. Chrysostom, and others. Many think that Christ here put Himself above Moses. But it would be more fitly said that Christ here compared Himself with the Jєωs, who, according to the law of Moses, circuмcised on the Sabbath. But Moses never expressly commanded this. It was merely inferred from his words.

John 7:24

"Judge not according to appearance."

What is, "according to appearance"? "Do not, since Moses has the greatest honor among you, give your decision according to your estimation of persons, but according to the nature of things; for this is to judge rightly. Wherefore has no one of you reproved Moses? Wherefore has no one disobeyed him when he orders that the Sabbath be broken by a commandment introduced from without into the Law? He allows a commandment to be of more authority than his own Law; a commandment not introduced by the Law, but from without, which is especially wonderful; while you who are not lawgivers are beyond measure jealous for the Law, and defend it. Yet Moses, who orders that the Law be broken by a commandment which is not of the Law, is more worthy of confidence than you." By saying then, (I have made) "a whole man (healthy)," He shows that circuмcision also was "partial" health. And what was the health procured by circuмcision? "Every soul," It says, "that is not circuмcised, shall be utterly destroyed." Genesis 17:14 "But I have raised up a man not partially afflicted, but wholly undone." "Judge not," therefore, "according to appearance."

Be we persuaded that this is said not merely to the men of that time, but to us also, that in nothing we pervert justice, but do all in its behalf; that whether a man be poor or rich, we give no heed to persons, but enquire into things. "You shall not pity," It says, "the poor in judgment." Exodus 23:3 What is meant? "Be not broken down, nor bent," It says, "if he that does the wrong be a poor man." Now if you may not favor a poor man, much less a rich. And this I say not only to you who are judges, but to all men, that they nowhere pervert justice, but preserve it everywhere pure. "The Lord," It says, "loves righteousness"; and, "he that loves iniquity hates his own soul." Psalm 11:7, Septuagint Let us not, I entreat, hate our own souls, nor love unrighteousness. For certainly its profit in the present world is little or nothing, and for the world to come it brings great damage. Or rather, I should say, that not even here can we enjoy it; for when we live softly, yet with an evil conscience, is not this vengeance and punishment? Let us then love righteousness, and never look aside from that law. For what fruit shall we gain from the present life, if we depart without having attained unto excellence? What there will help us? Will friendship, or relations, or this or that man's favor? What am I saying? This or that man's favor? Though we have Noah, Job, or Daniel for a father, this will avail us nothing if we be betrayed by our own works. One thing alone we need, that is, excellency of soul. This will be able to carry you safe through, and to deliver you from everlasting fire, this will escort you to the Kingdom of Heaven. To which may we all attain, through the grace and lovingkindness of our Lord Jesus Christ, by whom and with whom, to the Father and the Holy Ghost be glory, now and ever and world without end. Amen.

6. "Judge not according to personal appearance, but judge righteous judgment." What is this? Just now, you who by the law of Moses circuмcise on the Sabbath day are not angry with Moses; and because I made a man whole on the Sabbath day you are angry with me. You judge by the person; give heed to the truth. I do not prefer myself to Moses, says the Lord, who was also the Lord of Moses. So consider us as you would two men, as both men; judge between us, but judge a true judgment; do not condemn him by honoring me, but honor me by understanding him. For this He said to them in another place: "If you believed Moses ye would certainly believe me also, for he wrote of me." John 5:46 But in this place He willed not to say this, Himself and Moses being as it were placed before these men for judgment. Because of Moses' law you circuмcise, even when it happens to be the Sabbath day, and will you not that I should show the beneficence of healing during the Sabbath? For the Lord of circuмcision and the Lord of the Sabbath is the same who is the Author of health; and they are servile works that you are forbidden to do on the Sabbath; if you really understand what servile works are, you sin not. For he that commits sin is the servant of sin. Is it a servile work to heal a man on the Sabbath day? You do eat and drink (to infer somewhat from the admonition of our Lord Jesus Christ, and from His words); at any rate, why do you eat and drink on the Sabbath, but because that what ye do pertains to health? By this ye show that the works of health are not in any wise to be omitted on the Sabbath. Therefore "do not judge by person, but judge righteous judgment." Consider me as you would a man; consider Moses as a man: if you will judge according to the truth, you will condemn neither Moses nor me; and when you know the truth you will know me, because I am the Truth.

7. It requires great labor in this world, brethren to get clear of the vice which the Lord has noted in this place, so as not to judge by appearance, but to keep right judgment. The Lord, indeed, admonished the Jєωs, but He warned us also; them He convicted, us He instructed; them He reproved, us He encouraged. Let us not imagine that this was not said to us, simply because we were not there at that time. It was written, it is read; when it was recited we heard it; but we heard it as said to the Jєωs; let us not place ourselves behind ourselves and watch Him reproving enemies, while we ourselves do that which the truth may reprove in us. The Jєωs indeed judged by appearance, but for that reason they belong not to the New Testament, they have not the kingdom of heaven in Christ, nor are joined to the society of the holy angels; they sought earthly things of the Lord; for a land of promise, victory over enemies, fruitfulness of child-bearing, increase of children, abundance of fruit — all which things were indeed promised to them by God, the True and the Good, promised to them, however, as unto carnal men, — all these things made for them the Old Testament. What is the Old Testament? The inheritance, as it were, belonging to the old man. We have been renewed, have been made a new man, because He who is the new man has come. What is so new as to be born of a virgin? Therefore, because there was not in Him what instruction might renew, because He had no sin, there was given Him a new origin of birth. In Him a new birth, in us a new man. What is a new man? A man renewed from oldness. Renewed unto what? Unto desiring heavenly things, unto longing for things eternal, unto earnestly seeking the country which is above and fears no foe, where we do not lose a friend nor fear an enemy; where we live with good affection, without any want; where no longer any advances, because none fails; where no man is born, because no man dies; where there is no hungering nor thirsting; where immortality is fullness, and truth our aliment. Having these promises, and pertaining to the New Testament, and being made heirs of a new inheritance, and co-heirs of the Lord Himself, we have a far different hope from theirs: let us not judge by appearance, but hold right judgment.

8. Who is he that judges not according to the person? He that loves equally. Equal love causes that persons be not accepted. It is not when we honor men in diverse measure according to their degrees that we ought to fear lest we are accepting persons. For where we judge between two, and at times between relations, sometimes it happens that judgment has to be made between father and son; the father complains of a bad son, or the son complains of a harsh father; we regard the honor which is due to the father from the son; we do not make the son equal to the father in honor, but we give him preference if he has a good cause: let us regard the son on an equality with the father in the truth, and thus shall we bestow the honor due, so that equity destroy not merit. Thus we profit by the words of the Lord, and that we may profit, we are assisted by His grace.

You're the one who needs to study more. St. Thomas Aquinas rejected the Immaculate Conception. That's not a straw being grasped. The IC inevitably became affirmed and defined as dogmatic truth by the Church. His rejection of IC was not a compliment of scripture.

I suppose Sr. Lucia's poor teeth and gummy smile also indicated character faults and hidden sin? Our Lady did not seem to agree.
