Why are there four Gospels?

There are four Gospels because God chose to give the Church four inspired, complementary testimonies to Jesus Christ. Together they proclaim one Gospel, the saving good news of His life, death, and Resurrection.

One Gospel in four accounts. Matthew, Mark, Luke, and John do not teach four different faiths. Each announces the same Lord and the same saving events. The Church therefore speaks of the fourfold Gospel. The Gospels occupy a unique place in Scripture because Jesus Christ is their center (CCC 125). Their differences give a fuller picture than a single account would provide.

Different purposes and audiences. Matthew frequently shows how Jesus fulfills the Old Testament and presents Him as the promised Messiah and authoritative teacher. Mark emphasizes Jesus' mighty deeds, His suffering, and the demanding call to discipleship. Luke highlights God's mercy, prayer, the Holy Spirit, the poor, and the universal reach of salvation. John speaks especially clearly about Christ's divine identity, His relationship with the Father, and the gift of eternal life (Jn 1:1-18; 20:30-31). These are emphases, not contradictions.

Why some details differ. The evangelists selected and arranged true material according to their purposes and the needs of their communities. One may summarize a speech while another gives a longer form. One may group teachings by theme while another places them in a different narrative setting. Ancient historical writing did not require modern transcript style. The Church teaches that the evangelists faithfully handed on what Jesus truly did and taught for our salvation (CCC 126; Dei Verbum 19).

Why only these four. Other writings about Jesus appeared in the ancient world, but the Church recognized Matthew, Mark, Luke, and John as apostolic, faithful to the rule of faith, and widely received in Christian worship. By the late second century, St. Irenaeus defended the fourfold Gospel as the Church's established inheritance. Later councils formally listed the same four within the canon of inspired Scripture. The Church did not create their inspiration. Guided by the Holy Spirit, she recognized the books God had given her (CCC 120).

How to read them. Matthew, Mark, and Luke are called the Synoptic Gospels because they share much material and can be viewed together. John often presents different events and extended discourses. Read each Gospel on its own terms before combining every detail. Start with Mark for a fast overview, then read Matthew or Luke, and finish with John. The four voices will lead you to the one Jesus whom they all proclaim.
