But you have an unction. When he was speaking of heretics, turning suddenly to his own, he says that they have an unction from the Holy One, so that on the contrary he may show that the heretics and all Antichrists are deprived of the gift of spiritual grace, and do not belong to him who is called Holy by the prophets. You know all things. You know the truth of faith and of life, taught by the unction of the Spirit, and you have no need to be taught, except that you persist in that which you have begun.
