The introduction of Christmas and its appointment on the 25th December brought about the establishment of three other festivals: 1. the feast of the _Circumcisio Domini_, eight days after the Nativity, according to St Luke ii. 21, (_postquam consummati sunt dies octo, ut circumcideretur puer, vocatum est nomen ejus Jesus_). 2. The Annunciation on the 25th March, which is also the day of Christ’s conception, and so is placed nine months before the 25th December. The historical evidence for this day is on a par with that for Christmas. 3. The Nativity of St John the Baptist, on the 24th June. Another consequence was that the festival of the _Occursus Domini_ (ὑπαπάτη), _i.e._ the meeting of our Lord with Simeon in the Temple, on Candlemas Day, which was observed in Jerusalem before the introduction of Christmas, had to be transferred to another day. According to the regulations of the Jewish Law in Lev. xii. 6, the period of uncleanness after birth lasted forty days. And according to St Luke ii. 22, Mary submitted to the Law in this respect. So long as our Lord’s birth was commemorated at Epiphany on the 6th January, the 15th February was the fortieth day after the Nativity, and so, as a matter of fact, the festival of the _Occursus Domini_ was celebrated in Jerusalem on this day in 385.[350] But when the Nativity came to be celebrated on the 25th December, the other festival had to be placed thirteen days earlier, on the 2nd February, as it is at the present time.[351] 2. _Advent and the Sundays until Septuagesima_ Christmas, like Easter, besides its Vigil and Octave, has also a considerable period of preparation. This, naturally, could only come into existence after the institution of the festival, and indeed a certain time had to elapse before it was organised. Since Christmas itself was first observed in the middle of the fourth century, it is not remarkable that the earliest clear reference to Advent, from an official source, dates from the end of the sixth century. Some sort of preparatory season to Christmas, however, existed before this. As in the case of Easter, this preparatory season was marked by a fast commencing on St Martin’s Day (11th November), and lasting until Christmas. All Mondays, Wednesdays, and Fridays were fasted as in Lent. Such was the preparation observed in Gaul since the appointment of the festival by Bishop Perpetuus of Tours († 491). The same observance existed in other parts of Gaul, for the first Council of Maçon (581) prescribes exactly the same order, and also that from St Martin’s Day to Christmas the Mass shall be the same as during Lent—the first sign of the liturgy for Advent. In the province of Tours there was a similar enactment, although affecting the monks alone, ordering them to fast through the whole of December.[352] The Roman Church did not observe the fast, although she treated Advent as a liturgical portion of the Church’s year and incorporated it therein.
