23 Now let us recur to the proof out of the Prophets which I spoke of. The Lord was crucified; you have received the testimonies. You see this spot of Golgotha! You answer with a shout of praise, as if assenting. See that you recant not in time of persecution. Rejoice not in the Cross in time of peace only, but hold fast the same faith in time of persecution also; be not in time of peace a friend of Jesus, and His foe in time of wars. You receive now remission of your sins, and the gifts of the King's spiritual bounty; when war shall come, strive thou nobly for your King.
Jesus, the Sinless, was crucified for you; and will you not be crucified for Him who was crucified for you? You are not bestowing a favour, for you have first received; but you are returning a favour, repaying your debt to Him who was crucified for you in Golgotha. Now Golgotha is interpreted, “the place of a skull.” Who were they then, who prophetically named this spot Golgotha, in which Christ the true Head endured the Cross? As the Apostle says, Who is the Image of the Invisible God; and a little after, and He is the Head of the body, the Church. And again, The Head of every man is Christ; and again, Who is the Head of all principality and power. The Head suffered in “the place of the skull.”
O wondrous prophetic appellation! The very name also reminds you, saying, “Think not of the Crucified as of a mere man; He is the Head of all principality and power. That Head which was crucified is the Head of all power, and has for His Head the Father; for the Head of the man is Christ, and the Head of Christ is God.”
