8 Do you understand what I have said? Attend carefully my beloved. There are divine names, and there are human names. God has received from me, and He Himself has given to me. Give me yours, and take mine He says. You have need of mine: I have no need of yours, but you have of mine inasmuch as my nature is unmixed, but you are a human being encompassed with a body, seeking also corporeal terms in order that, by borrowing expressions which are familiar to you, thou who art thus encompassed with a body, may be able to think on thoughts which transcend your understanding.
What kind of names has He received from me, and what kind has He given to me? He Himself is God, and He has called me God; with Him is the essential nature as an actual fact, with me only the honour of the name: “I have said you are gods, and you are all children of the most highest.” Here are words, but in the other case there is the actual reality. He has called me god, for by that name I have received honour. He Himself was called man, he was called Son of man, he was called the Way, the Door, the Rock.
These words He borrowed from me; the others He gave from Himself to me. Wherefore was He called the Way? That you might understand that by Him we have access to the Father. Wherefore was He called the Rock? That you might understand the secure and unshaken character of the faith. Wherefore was He called the Foundation? That you might understand that He upholds all things. Wherefore was He called the Root? That you might understand that in Him we have our power of growth. Wherefore was He called the Shepherd?
Because He feeds us. Wherefore was He called a sheep? Because He was sacrificed for us and became a propitiatory offering. Wherefore was He called the Life? Because He raised us up when we were dead. Wherefore was He called the Light? Because He delivered us from darkness. Why was He called an Arm? Because He is of one substance with the Father. Why was He called the Word? Because He was begotten of the Father. For as my word is the offspring of my spirit, even so was the Son begotten of the Father.
Wherefore is He called our raiment? Because I was clothed with Him when I was baptized. Why is He called a table? Because I feed upon Him when I partake of the mysteries. Why is He called a house? Because I dwell in Him. Why is He called an inmate of the house? Because we become His Temple. Wherefore is He called the Head? Because I have been made a member of His. Why is He called a Bridegroom? Because He has taken me as His bride. Wherefore is He called undefiled? Because He took me as a virgin. Wherefore is He called Master? Because I am His bondmaid.
