In the last few centuries, historians, for whatever reasons, began to doubt Jesus Christ as God and man who really lived on earth two thousand years ago. The work therefore has an apologetic purpose: to justify the historicity of Jesus Christ and the historical foundation of the Christian faith using the historical-scientific method. The first part of the paper analyzes the Holy Scriptures as a historical document from which data on the historical existence of Jesus Christ could be extracted. The problem of approach to Jesus research is analyzed. This is followed by a critical analysis of the Gospels as reliable historical documents and an analysis of the Epistles of the Apostle Paul as a confirmation of the truthfulness of the contents of the Gospels. At the end of the first part, the event of the Resurrection itself was analyzed and critically examined as a supernatural but certain event in the history of mankind. The second part of the paper compares extra-biblical testimonies about Jesus, Christian and non-Christian sources. Church figures and Christian documents of the first centuries clearly confirm the truth and authority of the Gospel and tradition. Then the testimonies of Roman, Jewish and Syrian writers are listed, who clearly mention Jesus Christ in their works and thus confirm the truthfulness of the events described in the Gospels. The third part of the paper talks about the consensus of contemporary historiography, according to which there is no doubt that Jesus Christ is a historical person. At the end of the paper, a short and basic chronology of Jesus' life is given.
