Pope Julius I Elected
A pope who set Christmas on December 25
The Christian community of Rome elected Julius I as their new bishop and pope. His pontificate would be defined by bold assertions of papal authority, particularly in his defense of Athanasius against the powerful Arian bishops of the East. Julius is also credited with establishing December 25 as the official date of Christ's birth, a decision that would shape the rhythm of the Western calendar for all centuries to come.
