Matt 6:2 · Douay-Rheims
“Therefore when thou dost an almsdeed, sound not a trumpet before thee, as the hypocrites do in the synagogues and in the streets, that they may be honoured by men. Amen I say to you, they have received their reward.”

“Let not thy left hand know what thy right hand doeth, is said as an extreme expression, as much as to say, If it were possible, that you should not know yourself, and that your very hands should be hid from your sight, that is what you should most strive after.”

Augustine of Hippo Patristic

“(ubi sup.) As then the hypocrites, (a word meaning ‘one who feigns,’) as personating the characters of other men, act parts which are not naturally their own—for he who personates Agamemnon, is not really Agamemnon, but feigns to be so—so likewise in the Churches, whosoever in his whole conduct desires to seem what he is not, is a hypocrite; he feigns himself righteous and is not really so, seeing his only motive is praise of men.”

“(ubi sup.) This refers to what He had said above, Otherwise ye shall have no reward of your Father which is in heaven; and He goes on to shew them that they should not do their alms as the hypocrites, but teaches them how they should do them.”

Augustine of Hippo Patristic

“(ubi sup.) But according to this interpretation, it will be no fault to have a respect to pleasing the faithful; and yet we are forbidden to propose as the end of any good work the pleasing of any kind of men. Yet if you would have men to imitate your actions which may be pleasing to them, they must be done before unbelievers as well as believers. If again, according to another interpretation, we take the left hand to mean our enemy, and that our enemy should not know when we do our alms, why did the Lord Himself mercifully heal men when the Jews were standing round Him? And how too must we deal with our enemy himself according to that precept, If thy enemy hunger, feed him. (Prov. 25:21.) A third interpretation is ridiculous; that the left hand signifies the wife, and that because women are wont to be more close in the matter of expense out of the family purse, therefore the charities of the husband should be secret from the wife, for the avoiding of domestic strife. But this command is addressed to women as well as to men, what then is the left hand, from which women are bid to conceal their alms? Is the husband also the left hand of the wife? And when it is commanded such that they enrich each other with good works, it is clear that they ought not to hide their good deeds; nor is a theft to be committed to do God service. But if in any case something must needs be done covertly, from respect to the weakness of the other, though it is not unlawful, yet that we cannot suppose the wife to be intended by the left hand here is clear from the purport of the whole paragraph; no, not even such an one as he might well call left. But that which is blamed in hypocrites, namely, that they seek praise of men, this you are forbid to do; the left hand therefore seems to signify the delight in men’s praise; the right hand denotes the purpose of fulfilling the divine commands. Whenever then a desire to gain honour from men mingles itself with the conscience of him that does alms, it is then the left hand knowing what the right hand, the right conscience, does. Let not the left hand know, therefore, what the right hand doeth, means, let not the desire of men’s praise mingle with your conscience. But our Lord does yet more strongly forbid the left hand alone to work in us, than its mingling in the works of the right hand. The intent with which He said all this is shewn in that He adds, that your alms may be in secret; that is, in that your good conscience only, which human eye cannot see, nor words discover, though many things are said falsely of many. But your good conscience itself is enough for you towards deserving your reward, if you look for your reward from Him who alone can see your conscience. This is that He adds, And your Father which seeth in secret shall reward you. Many Latin copies have, openlya.”

Gregory the Great Patristic

“(Mor. xxxi. 13.) It should be known, that there are some who wear the dress of sanctity, and are not able to work out the merit of perfection, yet who must in no wise be numbered among the hypocrites, because it is one thing to sin from weakness, another from crafty affectation.”

Isidore of Seville Patristic
c. A.D. 560–636
“(Etym. x. ex Aug. Serm.) The name ‘hypocrite’ is derived from the appearance of those who in the shows are disguised in masks, variously coloured according to the character they represent, sometimes male, sometimes female, to impose on the spectators while they act in the games.”

Pseudo-Chrysostom Patristic
“(Hom. xv.) He opposes three chief virtues, alms, prayer, and fasting, to three evil things against which the Lord undertook the war of temptation. For He fought for us in the wilderness against gluttony; against covetousness on the mount; against false glory on the temple. It is alms that scatter abroad against covetousness which heaps up; fasting against gluttony which is its contrary; prayer against false glory, seeing that all other evil things come out of evil, this alone comes out of good; and therefore it is not overthrown but rather nourished of good, and has no remedy that may avail against it but prayer only.”

“(Comm. in Tim. 4, 8.) The sum of all Christian discipline is comprehended in mercy and piety, for which reason He begins with almsgiving.”
Pseudo-Chrysostom Patristic
“The trumpet stands for every act or word that tends to a display of our works; for instance, to do alms if we know that some other person is looking on, or at the request of another, or to a person of such condition that he may make us return; and unless in such cases not to do them. Yea, even if in some secret place they are done with intent to be thought praiseworthy, then is the trumpet sounded.”

Glossa Ordinaria Medieval
“(non occ.) In the words, in the streets and villages, he marks the public places which they selected; and in those, that they may receive honour of men, he marks their motive.”
Pseudo-Chrysostom Patristic
“The Apostles in the book of the Constitutions, interpret thus; The right hand is the Christian people which is at Christ’s right hand; the left hand is all the people who are on His left hand. He means then, that when a Christian does alms, the unbeliever should not see it.”
Pseudo-Chrysostom Patristic
“For it is impossible that God should leave in obscurity any good work of man; but He makes it manifest in this world, and glorifies it in the next world, because it is the glory of God; as likewise the Devil manifests evil, in which is shewn the strength of his great wickedness. But God properly makes public every good deed only in that world the goods of which are not common to the righteous and the wicked; therefore to whomsoever God shall there shew favour, it will be manifest that it was as reward of his righteousness. But the reward of virtue is not manifested in this world, in which both bad and good are alike in their fortunes.”
