I’ve seen atheists say that Christianity is based off of Mithraism, noting that many of the details between Mithra and Christ are the same.
Some of the supposed similarities are born of a virgin (on December 25th), teacher, 12 disciples, known as the “good shepherd,” “the way, the truth and the light.” Died, was buried in a tomb. Resurrected after three days.
Also, many say that Mithras was based on Horus. Horus was born on December 25th under an eastern star, was visited by three wise men, walked on water, and healed the sick.
How do we refute the claim that Christianity is just an evolution of Mithraism or Horus worship?
