BROTHERS and SISTERS, when Christ, Who is our life, is revealed, then you also will be revealed with Him in glory. Put to death, therefore, what is earthly in you: sexual immorality, impurity, passion, lust, and greed, which is idolatry. Because of these things, the wrath of God is coming upon the sons of disobedience. You also once walked in these things when you lived in them. But now, you must get rid of all such things – anger, wrath, malice, blasphemy, and abusive language from your mouth. Do not lie to one another, since you have put off the old man with his practices and have put on the new man, who is renewed in knowledge according to the image of his Creator. In that renewal, there is no longer Greek or Jew, circumcised or uncircumcised, barbarian, Scythian, slave or free, but Christ is all and in all.
Saint Dorotheos of Gaza on "do not lie to one another, since you have put off the old man with his practices":
Forasmuch as all sins arise through a love of pleasure or avarice or vainglory, we can say that lying has its roots in these three vices: a person has to avoid blame and humiliation to fulfill his own desires or to gain something. A person whose very life is a lie is one who is licentious and pretends to be temperate, or a miser and speaks of almsgiving and compassion, or ostentatious and goes in raptures over poverty, not wanting to acquire the virtue he praises. A person whose very life is a lie: he is not a simple but a two-faced man. He is one thing on the inside and another on the outside.
