God... Truth or fiction?

:) Nowizard, what does the authenticity of the writings have to do with it? Firstly, we will never be able to verify this, and secondly, there is no need to verify it. What has come down to us from the history of both Christianity and paganism provides a quite complete picture of both. I am referring to a much deeper antiquity, about which there is also considerable evidence. In addition, many Orthodox holidays continue to be interpreted in their pre-Christian equivalent: Red Hill, Protection of the Theotokos, Presentation of Jesus at the Temple, Maslenitsa, etc. Ivan Kupala remains Ivan Kupala.
