Two broad approaches
Many conservative Christians hold that the New Testament presents an accurate, divinely guided account of Jesus as both human and divine. From this perspective, similarities with earlier traditions do not determine the meaning or truth of the Christian story.
Other Christian and non-Christian scholars emphasize the development of oral tradition, literary shaping and the distance between Jesus' lifetime and the composition of the Gospels. They may interpret some Gospel episodes as narratives influenced by the religious world of the ancient Mediterranean and Near East.
Read comparisons carefully
A shared motif does not by itself prove direct borrowing. Similar stories can arise through cultural contact, common human concerns, independent development or later interpretation. Each proposed parallel needs attention to dates, sources, language and context.
