O Spirit of all-perfect purity, before whose light an angel veils his face, cleanse our hearts and minds, thou who didst cleanse the lips of the prophet Isaiah with a burning coal from Thine altar. O all-purifier help us to keep our souls unspotted from the world, aid us so that we may walk lightly on the dusty path of life and return unsoiled into the heavenly city, there to be united with God our parent.
The lesson is taken from the words of the Holy Prophet Mani:
When the immortal light is led up to the gods, then will both the zenith and the nadir of heaven be brought together, for the custody of splendor will seize the topmost heaven. Then will appear the kingdom of the God of Wisdom; those gods who are in all the regions of the heavens and the earths, and they will bestow a blessing on the men who are righteous and they will become rulers in the kingdom. They shall themselves see him, the Image of the Light, all rejoicing and being glad over him. Desire shall depart from them with all other kinds of temptation. When they wish they shall clothe themselves with their body and gain the victory over it, and they shall find the way from it to the kingdom of life made smooth.
The gospel is taken from the Gospel according to St. John:
And Jesus said: Holy Father, keep through Thine own Name those whom Thou hast given Me, that they may be one, as We are. I pray not that Thou shouldest take them out of the world, but that Thou shouldest keep them from the evil. They are not of the world, even as I am not of the world. Sanctify them through Thy truth; Thy word is truth. Neither pray I for these alone, but for them also who shall believe on Me through their word; that they all may be one, as Thou, Father art in Me, and I in Thee, and they also may be one in Us. The glory which Thou gavest Me I have given them; that they may be as one, as We are one. I in them, and Thou in Me, that they may be perfect in one; and that the world may know that Thou hast loved them, as Thou hast loved Me. I will that they also, whom Thou hast given Me, be with Me where I am. I have declared unto them Thy Name, that the love wherewith Thou hast loved Me may be in them, and I in them.
