Now I am reminding you, brothers, of the gospel I preached to you, which you indeed received and in which you also stand. Through it you are also being saved, if you hold fast to the word I preached to you, unless you believed in vain. For I handed on to you as of first importance what I also received: that Christ died for our sins in accordance with the scripture s that he was buried; that he was raised on the third day in accordance with the scripture s, that he appeared to Cephas, then to the Twelv e. After that, he appeared to more than five hundred brothers at once, most of whom are still living, though some have fallen asleep. After that he appeared to James, then to all the apostles. Last of all, as to one born abnormally, he appeared to m e. For I am the least of the apostles, not fit to be called an apostle, because I persecuted the church of God. 1 Cor. 15:1-9
The Acts of the Apostles describe the preaching and the signs and wonders that the Apostles performed. The preaching of the apostles formed the basis for the Gospel accounts of Jesus’ life that are generally not recounted in the various epistles of the early Church. Paul assumed that his audience had already heard the oral Gospel.Brothers and sisters: If then you were raised with Christ, seek what is above, where Christ is seated at the right hand of God. Think of what is above, not of what is on earth. For you have died, and your life is hidden with Christ in God. When Christ your life appears, then you too will appear with him in glory. Col. 3:1-4.
Luke was not making a story up, but was probably recounting the Gospel that Paul preached. Pastoral letters like Paul’s letters continued to be written and were included in the New Testament by the early Church, even after St. Paul was executed. In fact, Christians from the earliest times produced volumes of literature concerning the faith. That is why we know so much about the divisions in the early Church. The Gospels, however, tried to compile the apostolic preaching as each community that produced a Gospel understood that story.Since many have undertaken to compile a narrative of the events that have been fulfilled among us , just as those who were eyewitnesses from the beginning and ministers of the word have handed them down to us . I too have decided, after investigating everything accurately anew, to write it down in an orderly sequence for you, most excellent Theophilus, so that you may realize the certainty of the teachings you have received. Lk. 1:1-6
