1 John 2:20 - Coke's Commentary on the Holy Bible

But ye have an unction, &c.— Both kings and priests were consecrated to their offices by anointing; and in the New Testament, wherein the title of kings and priests is given to true believers, by anointing we are to understand any divine grace imparted to true believers. The apostle's meaning therefore is to this effect: "The Spirit of truth and holiness, which Christ the Holy One of God hath poured forth upon you, is to guide you into all truth; so that you havean experimental knowledge of all things relating to the pure gospel, at least so far as is necessary to salvation."
