Advent Approaches

 It cannot be determined with any degree of certainty when the celebration of Advent was first introduced into the Church. The preparation for the feast of the Nativity of Our Lord was not held before the feast itself existed, and of this we find no evidence before the end of the fourth century, when, according to Duchesne [Christian Worship (London, 1904), 260], it was celebrated throughout the whole Church, by some on 25 December, by others on 6 January. Of such a preparation we read in the Acts of a synod held at Saragossa in 380, whose fourth canon prescribes that from the seventeenth of December to the feast of the Epiphany no one should be permitted to absent himself from church. We have two homilies of St. Maximus, Bishop of Turin (415-466), entitled "In Adventu Domini", but he makes no reference to a special time. The title may be the addition of a copyist. There are some homilies extant, most likely of St. Caesarius, Bishop of Arles (502-542), in which we find mention of a preparation before the birthday of Christ; still, to judge from the context, no general law on the matter seems then to have been in existence. A synod held (581) at Mâcon, in Gaul, by its ninth canon orders that from the eleventh of November to the Nativity the Sacrifice be offered according to the Lenten rite on Monday, Wednesday, and Friday of the week. The Gelasian Sacramentary notes five Sundays for the season; these five were reduced to four by Pope St. Gregory VII (1073-85). The collection of homilies of St. Gregory the Great (590-604) begins with a sermon for the second Sunday of Advent. In 650 Advent was celebrated in Spain with five Sundays. Several synods had made laws about fasting to be observed during this time, some beginning with the eleventh of November, others the fifteenth, and others as early as the autumnal equinox. Other synods forbade the celebration of matrimony. In the Greek Church we find no documents for the observance of Advent earlier than the eighth century. St. Theodore the Studite (d. 826), who speaks of the feasts and fasts commonly celebrated by the Greeks, makes no mention of this season. In the eighth century we find it observed not as a liturgical celebration, but as a time of fast and abstinence, from 15 November to the Nativity, which, according to Goar, was later reduced to seven days. But a council of the Ruthenians (1720) ordered the fast according to the old rule from the fifteenth of November. This is the rule with at least some of the Greeks. Similarly, the Ambrosian and the Mozarabic Rites have no special liturgy for Advent, but only the fast.

In short, Christmas, via Advent, was already impinging on November (with observances starting as early as November 11th for Christmas Day on December 25th, or maybe even January 6th) by the 6th century.

The more things change....

The next day John was there again with two of his disciples, and as he watched Jesus walk by, he said, "Behold, the Lamb of God." The two disciples heard what he said and followed Jesus. Jesus turned and saw them following him and said to them, "What are you looking for?"  They said to him, "Rabbi (which translated means Teacher), "where are you staying?" He said to them, "Come, and you will see."  So they went and saw where he was staying, and they stayed with him that day.  It was about four in the afternoon. Andrew, the brother of Simon Peter, was one of the two who heard John and followed Jesus.
