Actually he has a point , they are pretty sure Jesus was born in the summer . The church decided to make the celebration in December in order to counter a pagan holiday of the time . Think of it like presidents day , neither president was born on that day , but that is when we decide to celebrate it . Germany surrendered officially on May 8th , but the Soviet Union decided to have the official celebrations observed on the 9th , I could go on , but in the end , what difference does it make ? it doesnt . Its not a betrayal , its a celebration by choice , the bible also doesnt require us to celebrate it at all , no reason why we shouldnt either . Where is the betrayal ?
