...baptism.
John Chrysostom gave a sermon in Antioch on December 20th, 386 AD which gives us a nice insight into how the Christmas date and celebration began to develop more:
For from this feast [that is, the Nativity], the Theophany and the holy Pascha and the Ascension and the Pentecost take their origin and foundation, for if Christ had not been born according to the flesh, he could not have been baptised, which is the Theophany; he could not have been crucified, which is the Pascha; he could not have sent the Spirit, which is the Pentecost.
We see here that the reason for celebrating the Nativity flows logically out of the recognition of the other events...
