If you continue in my word, you shall be my disciples indeed: And you shall know the truth, and the truth shall make you free.” (St. John viii, 31-32)

Now this is life everlasting, that they may know thee, the only true God, and Jesus Christ, whom thou hast sent… I have given them thy word, and the world hath hated them, because they are not of the world: as I also am not of the world. I do not ask that thou take them away out of the world, but that thou preserve them from evil. They are not of the world: as I also am not of the world. Sanctify them in truth. Thy word is truth.” (St. John xvii, 3, 14-17)
