8 But now ye also put off all these; anger, wrath, malice, blasphemy, filthy communication out of your mouth.
[AD 407] John Chrysostom on Colossians 3:8
"But now put ye also away all these."

He speaks always both universally and particularly; but this is from earnestness.

"Anger, wrath, malice, railing, shameful speaking out of your mouth. Lie not one to another."

"Shameful speaking," he saith, "out of your mouth," clearly intimating that it pollutes it.

[AD 407] John Chrysostom on Colossians 3:8
But against others he advanceth his discourse. Under the head of "passion and railing" he means revilings, just as under "wrath" he means wickedness. And in another place, to shame them, he says, "for we are members one of another." He makes them out to be as it were manufacturers of men; casting away this one, and receiving that. He spoke of a man's "members"; here he saith, "all." He spoke of his heart, wrath, mouth, blasphemy, eyes, fornication, covetousness, hands and feet, lying, the understanding itself, and the old mind.

[AD 500] Desert Fathers on Colossians 3:8
A hermit said, ‘A monk ought not to listen to disparagement; he ought not to be disparaging, and he ought not to be scornful.’

[AD 1107] Theophylact of Ohrid on Colossians 3:8
How is this? He just said: "you once walked," showing by this that they no longer live that way, and suddenly he says again: put off all these things! How can they put off what they no longer have? To this one can answer that the phrase "you once walked" serves for the understanding of what is now being said. For by this it is suggested that "once," that is, before baptism, sin ruled in you, possessed your entire life, and tyrannized over you, and freedom from the passions was impossible for you; but now, when through baptism sin has been put to death in you, it has become easy for you to put off the passions like a garment. And you cannot put forward as an excuse that you live under the power of sin and the passions, for you have died to them.

By "malice" he means bearing grudges, which some have called resentment, when someone holds malice within himself against another, as if to take revenge.

The apostle speaks about abusive speeches.

Expressively he said: "your mouths," for your mouths are sanctified by partaking of the body of the Lord. Therefore it is extremely unfitting for you to defile with slander and foul language the mouths that receive Christ the Lord.

[AD 1274] Thomas Aquinas on Colossians 3:8
Above, the Apostle warned the faithful about sins of the flesh; here he warns them about spiritual sins. First, he lays down a general admonition; and secondly, he divides it into parts.

So he says: At one time you walked in sins, but now put them all away, not only sins of the flesh, but all sin: "So put away all malice and all guile and insincerity and envy and all slander" (1 Pet. 2:1).

He divides the spiritual sins into two groups: first, into sins of the heart, secondly, into sins of the mouth, spoken sins. First of all, he mentions anger: "For the anger of man does not work the righteousness of God" (Jas. 1:20); and this must be avoided. Secondly, he mentions wrath, which springs from anger, and occurs when a person considers someone unworthy of what he has, or in comparison with another: "I have no wrath" (Is 27:4). Malice then follows after these two, when a person tries to cause injury to his neighbor: "Put away all filthiness and rank growth of wickedness" (Jas. 1:21).

Then he mentions those sins committed by word; and there are three kinds. Such sins indicate a spiritual disorder. First, such a sin in relation to God is blasphemy: "Bring out of the camp him who blasphemed; and let all who hear him lay their hands upon his head, and let all the congregation stone him" (Lev 24:14). And thus all blasphemy is a grievous sin. But what if it is sudden? I answer that if it is so sudden that a person does not realize that he is blaspheming, it is not a grievous sin. But I believe that however suddenly, if a person realizes that he is speaking blasphemous words, he sins in a grievous way. Secondly, he mentions a disorder concerning concupiscence, when he says, put foul talk from your mouth: "Let no evil talk come out of your mouths" (Eph 4:29). Thirdly, he mentions a disorder in relation to our neighbor, lying: "A false witness will not go unpunished" (Prov 19:5).
