To understand the gospel in a macro perspective best there is an important launching point in the word “Christ”. The Greek word for it is christos. This was a Greek word used in the pagan world for one anointed with favor shown in oil to rule or command. This Greek word makes its way into the New Testament from early Christians who used that in the Greek translation of the Old Testament. But when they called Jesus the Christ, they meant also like how Jews turned Christians had the Hebrew term meshiach (Messiah). This was also seen through the lens of kingdom; but not just any kingdom but the kingdom, but of David.
This was shown in the Gospel of Mathew which says, “This is the genealogy of Jesus the Messiah the son of David, the son of Abraham (Mathew 1:1). In fact, there is much scholarship that suggests that the Gospel of Mathew was originally written in Hebrew, Aramaic or Syriac (the latter two being close derivatives of Hebrew) and then translated into Greek.
A good view of the kingdom of God in Christ is that the “Old is revealed in the New and the New is concealed in the Old” (St. Augustine). The gospel of Jesus Christ is articulated in covenantal language not embedded by shadows of covenantal promises like the law of Moses. Instead it is a matter of covenantal love with Jesus as the fulfillment of the Law of Moses. With this accomplished Jesus has a magnified expression of David’s line of succession and true worship. The following is a gospel proclamation of Jesus as the Anointed One. Notice that David is pointed to due to God’s covenantal faithfulness and an agenda that unfolds over the centuries.
Today in the town of David a Savior has been born to you; he is the Messiah, the Lord. This will be a sign to you: You will find a baby wrapped in cloths and lying in a manger.” Suddenly a great company of the heavenly host appeared with the angel, praising God and saying, “Glory to God in the highest heaven, and on earth peace to those on whom his favor rests.” (Luke 2:11-14).
A king is not really a king without a kingdom. But does the David reference extend to Christianity? And if so, what would it look like?
The writer of Hebrews touches on this with the reference of Mount Zion which is where King David was anointed king after all question of rivals was put aside. Writing to Christians it is described as transcendent stating, “But you have come to Mount Zion, to the city of the living God, the heavenly Jerusalem. You have come to thousands upon thousands of angels in joyful assembly (Hebrews 12:22).
The kingdom of God in Christ glorifies Christ, transcends earth, is universal for application and holistic to the person. Paul, a fulfilled Jew in Jesus as the Messiah, connected the gospel of Jesus to David.
the gospel he promised beforehand through his prophets in the Holy Scriptures regarding his Son, who as to his earthly life was a descendant of David, and who through the Spirit of holiness was appointed the Son of God in power by his resurrection from the dead: Jesus Christ our Lord (Romans 1:2-4).
In a way, one could say exactly where the “Mt. Zion” is for Christianity: the tomb of the Resurrection. The preaching of this is the whole gospel of the kingdom, for the whole person for the whole world. As of the term “appointed” this makes sense in light of the Isaiah prophecy that the “government shall be upon his shoulders” (Isaiah 9:6)).
Jesus as the son of David rules a kingdom now with the logical consequences of being who he is in a Davidic pattern of kingdom. On the fourth day of Jesus’ ministry Apostle Nathanael called him the King of Israel. Like King David, Jesus chose someone to have the keys over the household of faith as the chief steward. The chief steward also served the kings descended from David who were like a vice president or a chief of staff. The first for Christianity was born Simon son of John but was renamed Peter on the fifth day of his ministry. Peter could bind and loose like a household manager and chief teacher and there has been someone in that same chair for 2,000 years. The kingdom of Jesus has a Queen Mother named Mary instead of Bathseeba mother of Solomon. People came to the Queen Mother in each generation of David’s descendants for their intercession. Likewise, Mary interceded for his first miracle (John 2:1-11) on the seventh day of Jesus’s ministry. The Bible says that all generations will call her blessed. All of this is also what comes with the fulness o the gospel of the Lord Jesus Christ. Yes, King David is one more part of the tapestry in salvation history that inspired me to become Catholic.
