Here is a breakdown of the key symbolic elements:
At the heart of the image is Jesus Christ, standing upon the "True Rock." He is depicted as the fulfillment of the law and the prophets, standing between the tablets of the Law and under the descent of the Holy Spirit (the dove). This reinforces the verse: "One is your Master, even Christ; and all ye are brethren." His position above all other figures signifies His role as the sole Head of the Church.
On the left, King David is shown in his royal robes, holding his harp. Crucially, he is not sitting on a throne but is pointing toward Christ. This illustrates the idea that even the greatest earthly kings of Israel were merely "types" or pointers to the true King. He isn't claiming authority for himself; he is deferring to the "Rock" that is God alone.
On the right, you see an empty, ornate throne that has been pushed aside. This represents the "human office" or the "papacy" that the previous discussion critiqued. The people are not looking at the throne or a human leader; they are gathered in an "assembly of saints," bowing in devotion to Christ. This visually depicts the shift from a centralized human hierarchy back to a "plurality of brethren."
The scrolls and text floating in the sky act as divine decrees, weaving the specific KJV verses into the atmosphere of the scene:
"Cursed be the man...": A warning against putting ultimate trust in human leaders.
"The Lord our King": Reaffirming that salvation and law come from God, not an institution.
"All ye are brethren": Emphasizing the equality of believers under the Lordship of Jesus.
The large stone upon which Christ stands is inscribed with the question: "Who is the Christ, Son of the Living God?" This represents Peter’s confession from Matthew 16. By placing Christ directly on this "Rock," the image argues that the "foundation of the house" is the truth of who Jesus is, rather than the person of Peter himself.
