Well, the word ‘gospel’ literally means “good news”. For a summary of the Good News Christ taught I would suggest reading Matthew, chapters 1-28, Mark, chapters 1-16, Luke, chapters 1-24, and John, chapters 1-21. =)
If the question is, why did Christ not write anything down, I would answer that He never needed to. The gospel writers, through the inspiration of the Holy Spirit, did the job well enough.
From the Catholic Encyclopedia “Gospel”
…It is very likely derived from the Anglo-Saxon god (good) and spell (to tell), and is generally treated as the exact equivalent of the Greek euaggelion (eu well, aggello*, I* bear a message), and the Latin Evangelium, which has passed into French, German, Italian, and other modern languages. The Greek euaggelion originally signified the “reward of good tidings” given to the messenger, and subsequently “good tidings”.
Thanks for bringing this up. In fact, this should be the starting point for any discussion on the Gospel – defining the word itself. Many people are unaware that the word “Gospel” literally means good news or good tidings. The etymology of the word is revealing. There has to be a bearer, or messenger, of this good news.
The question, “What was Christ’s Gospel?” implies Jesus’ role as a messenger of some good news. Was Jesus really a messenger? What was His message of good tidings? Where did this message come from and for whom was it intended?
The prophet Malachi tells us that it was God the Father who promised to send a messenger into this world from heaven, bearing a message from Him: “Behold, I will send my messenger, and he shall prepare the way before me [and that messenger was John the Baptist, preparing the way before Jesus Christ, as explained in Mark 1:2]: and the Lord, whom ye shall seek, shall suddenly come to his temple, EVEN THE MESSENGER OF THE COVENANT [this “Messenger” now refers Jesus Christ], whom ye shall delight in” (Mal. 3:1).
Now, how do we know what was Jesus’ message – His Gospel – as the “messenger of the [new] covenant”?
When Peter first preached this Gospel to the Gentiles, he gives us very explicit directions for locating it. Peter said in Acts 10:36-37, “The word which God sent unto the children of Israel, preaching peace by Jesus Christ: (he is Lord of all) That word, I say, ye know, which was published throughout all Judea, and began from Galilee, after the baptism which John preached.”
Peter’s statement answers many questions which would help us identify Christ’s Gospel:
- With whom did this message [the Gospel] originate?
Peter said: “The word which God sent.” It came from God the Father.
- To whom did God send the message?
Peter said, “unto the children of Israel.” Although, at the time Peter made the statement, the Gospel was being opened up to Gentiles.
- By whom was it sent? Who was the messenger who brought and preached the message?
Peter said: “by Jesus Christ.” Jesus was the divine Messenger. Malachi called Him the Messenger of the New Covenant. The message, then, is the New Covenant Message – or the New Covenant Gospel. Moses was the mediator of the Old Covenant, and Jesus Christ of the New.
- Where was it first preached?
Peter said: It “began from Galilee.”
- When did Jesus begin to preach this Gospel in Galilee?
Peter said: “after the baptism which John preached.”
Now, we use these very definite directions to identify Christ’s Gospel message of the New Covenant. We go to the first chapter of Mark. Notice:
Verse 1: “The beginning of the gospel of Jesus Christ, the Son of God.”. – This clearly tells us of the record of the BEGINNING of Christ’s preaching of the Gospel.
V. 2-3: “As it is written in the prophets, Behold I send my messenger…” – acknowledging the fulfillment of Malachi’s prophecy in Mal. 3:1.
V. 4-13: “John did baptize in the wilderness…” – This relates the baptizing ministry of John, preaching, not the Gospel, but “the baptism of repentance,” which prepares the way for the Gospel.
V. 14: “Now after that John was put in prison” – there is the exact TIME for the beginning of the preaching of Christ’s Gospel – “Jesus” – there is the divine Messenger by whom God sent it – “came into Galilee” – the PLACE of the first preaching.
Now we have the TIME, the Israelites to WHOM God sent the Message, the PLACE, and the MESSENGER – so whatever we find Jesus preaching here must be Christ’s Gospel message of the New Covenant.
What do we read? “Jesus came into Galilee, PREACHING THE GOSPEL OF THE KINGDOM OF GOD.”
Christ’s Gospel then was the good news of the coming Kingdom of God, the same Gospel He instructed His disciples to preach to the world before He left them to be with the Father in heaven: “Go ye into all the world, and preach the gospel to every creature” (Mark 16:15).
The Gospel is not man’s gospel about the person of Christ. The Gospel, or specifically the Gospel of Jesus Christ, is the Gospel Christ brought as God’s Messenger. The Gospel He proclaimed is the Gospel of the coming Kingdom of God, as these Scriptures show. Christ came to the world not only to die for our sins but also to announce to the world the good news from the Father that “the kingdom of God is at hand” – that it will soon be a reality because His coming has paved the way for its establishment.
God bless.
