You have an anointing from the Holy One, and you know the truth.
The Gnostics claimed to have an "anointing." Gerald Paden says: "In a document cited by Hippolytus as representing a Gnostic sect known as Naassenes, we read: We alone of all men are Christians who complete the mystery at the third portal and are anointed there with speechless chrism. (Philosophuma, vol. 9, pp. 121-122)" (17). John meets the Gnostics on their own ground with their own terms. The "anointing" did not belong to the Gnostics "alone," as they claimed, but to Christians in general. The anointing is plainly the all sufficient word of God that has been entrusted into the care of every child of God.
