The notion of anointing suggests . . . 

that there is no distance between the Son and the Spirit. 

Indeed, just as between the surface of the body and the anointing with oil 

neither reason nor sensation recognizes any intermediary, 

so the contact of the Son with the Spirit is immediate, 

so that anyone who would make contact with the Son by faith 

must first encounter the oil by contact. 

In fact there is no part that is not covered by the Holy Spirit. 

That is why the confession of the Son's Lordship is made in the Holy Spirit 

by those who receive him, the Spirit coming from all sides 

to those who approach the Son in faith.
