St James was commemorated in the East on the 27th December. This is his date in the Arian martyrology, which is followed by the very ancient Carthaginian Calendar. Although the latter incorrectly adds that he was killed by Herod, it is evident that St James the Less is intended, for all the Eastern documentary sources place the commemoration of St James the Less in the Christmas season. They differ as to the day, some commemorating him on the 26th, some on the 28th, the Neapolitan and Mozarabic Calendars on the 29th, and the Syrian lectionary has his name both on the 28th December and on the 23rd October. In accordance with these ancient witnesses we would willingly place his death on the 27th December, but there are strong reasons against this. First, in these documents he is coupled for the most part with St John the Evangelist, and it is unlikely that both of them died on the same day. Secondly, in the most ancient document of all, the Arian martyrology, immediately after St James and St John, on the 28th December, come St Peter and St Paul, who suffered death on a different date altogether; the compiler simply placed the chief personages connected with our Lord on the days after Christmas. Thirdly, the church built by Helena on the Mount of Olives, in which St James and St John received special veneration, was dedicated on the 27th December.[632] Here again, as in so many other cases, the date of the church’s consecration became the date of the festival of the saint specially connected with it. Of course it may be thought that the church was consecrated on the day of the saint’s death, but for this there is, at any rate, no proof concerning this particular church. And so we must give up the 27th December as the real day of St James’s death. It may have been the day of his appointment to the episcopate.[633] That this is so is further confirmed by the accounts written by pilgrims, in which it is stated that St James was buried in the church on the Mount of Olives, and that he had owned a house in Jerusalem and a burial place, in which he had buried Zachary and Simeon.[634] It is true that later Latin authorities expressly give his _dies natalis_, _i.e._ the actual day of his death, on the 27th December,[635] but their evidence is not conclusive. In marked distinction from the Eastern tradition, the _Hieronymianum_ gives his death on the 25th March: “Hierosolyma passio Jacobi Justi,” or, as in the Bern codex, “fratris Domini.” This date coincides strikingly with the statement of Eusebius (_Hist. Eccl._, 2, 23, 11), that the death of St James happened during the season of Easter.
