Easter is "the first [month] of the year and the beginning of every age": ancient homily of Second Century Christianity

excerpt included by Markus Vinzent for his tome Christ's Resurrection in Early Christianity and the Making of the New Testament (Ashgate, 2011):

Let us say first then why this month is 'the beginning of months' and why the month of Pascha 'is the first of the months of the year.'  Now the esoteric Doctrine of the Hebrews says that this is the season in which the divine craftsman and maker of all things created the universe. . . I do not refuse to believe this explanation, but I think, or rather am convinced, that the spiritual feast of the Pascha is the reason why the beginning and head and supreme authority of all time and of the whole age is considered to be this month of the Pascha, in which this great mystery is accomplished and celebrated, so that, as the Lord is the first-begotten (John 1:18) and the first born of all the intelligible and invisible beings from the beginning (Colossians 1:15), so this month, which celebrates the sacred rite, has become the first of the year and the beginning of every age. (Homily on the Holy Pascha, 17, 1 - 3)
