“I also say to you that you are Peter, and upon this rock I will build My church; and the gates of Hades will not overpower it. I will give you the keys of the kingdom of heaven; and whatever you bind on earth shall have been bound in heaven, and whatever you loose on earth shall have been loosed in heaven.” (Matthew 16:18–19)
Having been a believer in Jesus Christ for over a half Century, something in these verses recently elicited my attention: the word keys—and the fact that it is plural. If I were to say that I had keys to my house I might be referring to front and back door locks that were keyed differently. Therefore, was Our Lord inferring that there were additional entrances to the kingdom of heaven? And if we could prove that there are many entrances into heaven, could those who proclaim that “all roads lead to heaven” be correct?
However, that would present a conflict of Scripture, for Jesus Christ stated that “I am the way, and the truth, and the life; no one comes to the Father but through Me.” (John 14:6). This concludes that the only way into God’s plan for salvation is by faith in His Son, Jesus Christ.
Explaining the Keys
The Greek verb from which ‘key’ is derived means to shut or close.1 We find that the noun ‘key’ (singular and plural) is used in the New Testament only 6 times. But it was used in ancient writings as early as the 8th Century B.C., as Dr. Beetham confirms that,
The noun occurs in Homer over 30 times to denote the bar to shut a door or, more specifically, a hook used to manipulate that bar. The term was then applied to a special wooden or metal instrument that served to move or unlock a bolt; thus the meaning “key.”2
However, observing the usage of ‘key’ in the New Testament, Greek scholars consistently state that it is used “metaphorically,”3 in a figurative manner. According to Dr. Unger, “the key is often used in Scripture as a symbol of power and authority, whether in church or state.”4 In this manner, Dr. Zodhiates explains its figurative meaning in the passage quoted at the outset:
The Lord designated Peter as the one who at Pentecost was going to open the kingdom of heaven to a great crowd which was of the Jewish stock (Acts 2) and later at Caesarea Maritime, which was of the Gentiles (Acts 10).5
Our Lord gave to Peter the keys—plural, being a dual authority. First, he declared the gospel of the grace of God to the Jews and secondly, he announced that this same gospel of grace was offered to the Gentiles. This is what the Apostle Paul would later proclaim as “the mystery which for ages has been hidden in God” (Ephesians 3:9).
This idea of power and authority is what shall be noted in the other uses of the word ‘key’ in the New Testament.
Key of Knowledge
“Woe to you lawyers! For you have taken away the key of knowledge; you yourselves did not enter, and you hindered those who were entering.” (Luke 11:52)
In the passage of Luke 11:45-52, Our Lord charges the lawyers with their malpractice in interpreting the Law. These lawyers are the Jewish scribes who were purportedly the experts in the interpretation of the Mosaic Law. Our Lord declared three ‘woes’ upon them, most notably that their interpretation of the Law “weigh men down with burdens hard to bear” (11:46) which they don’t even follow. The third ‘woe’ is that they “have taken away the key of knowledge” (11:52; cf. Malachi 2:7)—the power of knowledge. They withheld the correct knowledge of God’s Word pertaining to the attainment of eternal life. Instead they substituted “their wretched traditions”6 of a salvation obtained by works, which contradicted the grace of God (Ephesians 2:8).
Keys of Death and Hades
“And I have the keys of death and of Hades.” (Revelation 1:18b)
In John’s initial vision of the Revelation, Our Lord stated that He was in possession of the “keys of death and of Hades.” These are not physical keys but instead it follows the figurative meaning of the word—power and authority. This power and authority He has over the administration of these two realms: over the physical death of His creatures (Hebrews 9:27) and determining who is to be cast into the Lake of Fire (Revelation 21:15).
Key of David
And to the angel of the church in Philadelphia write: He who is holy, who is true, who has the key of David, who opens and no one will shut, and who shuts and no one opens, says this. (Revelation 3:7)
The mention of the “key of David” refers to a passage in Isaiah 22:22 where the key (power and authority) over the house of David was placed on the shoulder of Eliakim, the household administrator. Kiel and Delitzsch note:
The power of the keys consisted not only in the supervision of the royal chambers, but also in the decision who was and who was not to be received into the king’s service.7
The placement of the key on the shoulder of Eliakim alludes to Isaiah’s prophesy concerning the Christ: “And the government will rest on His shoulders” (Isaiah 9:6). And now by this declaration in Revelation 3:7, Jesus Christ, the son of David will have total power and authority over the Messianic Kingdom of David.
Key of the Bottomless Pit
Then the fifth angel sounded, and I saw a star from heaven which had fallen to the earth; and the key of the bottomless pit was given to him. (Revelation 9:1)
Here the angel is given the authority to open the bottomless pit and dispense the Fifth Trumpet judgment of locusts and scorpions.
Key of the Abyss
Then I saw an angel coming down from heaven, holding the key of the abyss and a great chain in his hand. (Revelation 20:1)
In this verse we observe an angel, not physically holding an actual key, but instead possessing the power and authority to access the abyss along with a chain in order to “handcuff” and restrain Satan in order to throw him into the abyss. This abyss is defined as “a prison in which evil powers are confined and out of which they can at times be let loose.”8 Satan will stay in the abyss and be released after the thousand years of the Millennium Kingdom (Revelation 20:7).
Conclusion
The word key is never used in Scripture as an instrument for unlocking a door or a padlock. Nor is it used to describe an essential (key) person or a fundamental (key) point in a discussion. It is used figuratively of a given power or authority to open a divinely administered realm or knowledge of truth.
