The Nativity : Chapter 12-75

I realized that the Primitive Roman Catholic Church’s calendar were different from the Primitive Greek Orthodox Church’s calendar for every thirteen days.
September 8: Mary was born. (The Primitive Roman Catholic Church had this theory).
→ September 21: Mary was born. (The Primitive Greek Orthodox Church had this theory. Its calendar was the Julian calendar).
June 24: John the Baptist was born. (The Primitive Roman Catholic Church had this theory).
→ July 7: John the Baptist was born. (The Primitive Greek Orthodox Church had this theory. Its calendar was the Julian calendar).
December 25: Jesus was born. (The Primitive Roman Catholic Church had this theory).
→ January 7: Jesus was born. (The Primitive Greek Orthodox Church had this theory. Its calendar was the Julian calendar).
Therefore, I realized that the Primitive Roman Catholic Church’s scholars knew that Jesus Christ was born on December 25 by the Holy Tradition.
