You hypocrite, first cast out the beam out of your own eye; and then shall you see clearly to cast out the speck out of your brother's eye.
Read Chapter 7
Augustine of Hippo
AD 430
Rarely, therefore, and in a case of great necessity, are rebukes to be administered; yet in such a way that even in these very rebukes we may make it our earnest endeavour, not that we, but that God, should be served. For He, and none else, is the end: so that we are to do nothing with a double heart, removing from our own eye the beam of envy, or malice, or pretence, in order that we may see to cast the mote out of a brother's eye. For we shall see it with the dove's eyes—such eyes as are declared to belong to the spouse of Christ, whom God has chosen for Himself a glorious Church, not having spot or wrinkle, i.e. pure and guileless.
As if he perhaps have sinned in anger, and you correct him with settled hate. For as great as is the difference between a beam and a mote, so great is the difference between anger and hatred. For hatred is anger become inveterate. It may be if you are angry with a man that you would have him amend, not so if you hate him.
Serm. in Mont., ii, 19: For to reprove sin is the duty of the good, which when the bad do, they act a part, dissembling their own character, and assuming one that does not belong to them.
For having removed from our own eye the beam of envy, of malice, or hypocrisy, we shall see clearly to cast the beam out of our brother’s eye.
Otherwise; The sin against the Holy Spirit is to take from God power which has influences, and from Christ substance which is of eternity, through whom as God came to man, so shall man likewise come to God. As much greater then as is the beam than the mote, so much greater is the sin against the Holy Spirit than all other sins. As when unbelievers object to others carnal sins, and secrete in themselves the burden of that sin, to wit, that they trust not the promises of God, their minds being blinded as their eye might be by a beam.
Here His will is to signify the great wrath, which He has against them that do such things. For so, wheresoever He would indicate that the sin is great, and the punishment and wrath in store for it grievous, He begins with a reproach. As then unto him that was exacting the hundred pence, He said in His deep displeasure, Thou wicked servant, I forgave you all that debt; Matthew 18:32 even so here also, Thou hypocrite. For not of protecting care comes such a judgment, but of ill will to man; and while a man puts forward a mask of benevolence, he is doing a work of the utmost wickedness, causing reproaches without ground, and accusations, to cleave unto his neighbors, and usurping a teacher's rank, when he is not worthy to be so much as a disciple. On account of this He called him hypocrite. For thou, who in other men's doings art so bitter, as to see even the little things; how have you become so remiss in your own, as that even the great things are hurried over by you?
First cast out...
Many do this, if they see a Monk having a superfluous garment, or a plentiful meal, they break out into bitter accusation, though themselves daily seize and devour, and suffer from excess of drinking.
Otherwise; This is spoken to the doctors. For every sin is either a great or asmall sin according to the character of the sinner. If he is a laic, it is small and a mote in comparison of the sin of a priest, which is the beam.
That is, with what face can you charge your brother with sin, when yourself are living in the same or a yet greater sin?.
Otherwise; “How sayest thou to thy brother;” that is, with what purpose? From charity, that you may save your neighbour? Surely not, for you would first save yourself. You desire therefore not to heal others, but by good doctrine to cover bad life, and to gain praise of learning from men, not the reward of edifying from God, and you are a hypocrite; as it follows, “Thou hypocrite, cast first the beam out of thine own eye.”.
And it is to be noted,...
. He who would rebuke others ought to be blameless himself. If he himself has a plank in his eye, that is, some great sin, and he finds fault with another who has only a speck, he causes that man to be even more shameless in his sin. The Lord shows that he who has sinned greatly is not even able to see clearly the sin of his brother. For how could one who has a plank in his eye even see another man who is only slightly injured.
