Astrological theorists argue that the story of Jesus is actually a solar myth, claiming that because the sun enters into each sign of the zodiac at 30 degrees, the "Sun of God" is said to begin his ministry at "age" 30. However, Luke 3:23 explicitly tells us that Jesus was about thirty years of age, not exactly thirty. Furthermore, beginning one's public service at age thirty was a standard cultural and religious milestone in ancient Judaism (such as for priests), not a coded reference to astrology.
