Maureen Mullarkey confirms Puritans’ objections (via Rorate Caeli):
It is easy to forget that Christmas as we know it is something of a latecomer. It was not celebrated in the early Church. Christians in the first two or three centuries understood themselves to be an Easter people, persecuted inheritors of the promise of the Resurrection. The death and resurrection of Jesus was the heartsblood of the faith. Within a community marked for martyrdom, it was the death date that earned commemoration. Death marked the day of initiation into eternal life, into the stunning mystery of Christ’s victory over death.
Absent the Resurrection, there was no counter to the words of Jeremiah: “Cursed be the day on which I was born.” Origen was emphatic on the matter:
Not one from all the saints is found to have celebrated a festive day or a great feast on the day of his birth. No one is found to have had joy on the day of the birth of his son or daughter. Only sinners rejoice over this kind of birthday.
Prior to the fourth century, there is scarce, if any, written evidence of an annual celebration of the Nativity on December 25th. Not until the fourth century—as newly unshackled Christianity spread northward from Jerusalem, north Africa, and the Mediterranean, into central and northern Europe—did popular custom ingest facets of those pre-Christian winter festivals that greeted its arrival.
