I wish to remind you, O brethren, about lying, for I see that you do not strive very hard to restrain your tongues and from this we are easily drawn into much evil. Make note my brethren that in every matter, as I constantly tell you, one may acquire a habit either for the good or for the evil; and so one needs great heedfulness so that we will not be robbed by lying, for one who lies has no union with God. Lying is foreign to God. In the scripture it is said that Lying is from the evil one, and for he is a liar, and the father of it (Jn. 8:44). See how the devil is called the father of lies, while truth is God, for He Himself said, I am the way, the truth and the life (Jn. 14:6). Therefore you see from whom we separate ourselves, and with whom we join ourselves by lying: evidently with the evil one. And so if in truth we wish to be saved, we must with our whole soul and all our striving love the truth and keep ourselves from every lie, lest it separate us from truth and from life.
There are three forms of lies: one lies in thought, another lies by word, and another lies by his very life. He lies by thought who takes for truth his own suppositions, that is, vain suspicions against his neighbor; when he sees someone conversing with a brother, he makes his own conjectures and says, "He is speaking about me." If they stop talking he again supposes that it is for his sake that they have stopped. If someone says a word, he suspects that it was said in order to insult him. All the time and in every matter he takes note of his neighbor, saying, "He did this for my sake, he said this because of me, he did this for such and such a reason. A man like this lies in thought, for he says nothing true, but everything out of suspicion alone, and from this proceed: curiosity, evil speaking, eavesdropping, enmity, condemnation.
