The fact is plain. The later Frankish recension of the Gregorian Sacramentary contained for the Sunday after Pentecost a Mass in honour of the Holy Trinity, with the same preface which is still in use.[269] In addition to this, Bishop Stephen of Liège drew up a suitable office, and so all was in readiness for the institution of an especial feast in honour of the Trinity, which, in the natural course of things, was fixed for the first Sunday after Pentecost. The custom of regarding it as a festival became more and more popular in the Netherlands, England, Germany, and France. Several diocesan synods expressed themselves in favour of it, _e.g._, that of Arles in 1260. As we have found in other instances, so here, it was the monasteries which prepared the way for the adoption of the festival. Thus, for example,[270] the Cistercians adopted the festival in 1270, the Cluniacs still earlier. The introduction of the festival into each diocese followed gradually in course of time, and it belongs to local historians to investigate the circumstances in each case. Although Alexander II. had officially declared the festival to be superfluous,[271] it nevertheless continued to increase in popularity in ever-widening circles. Its adoption did not follow any uniform law, for in several places it was observed on the last Sunday after Pentecost, as in several dioceses of France, until on in the seventeenth century, and here and there we find it kept with an octave. Uniformity was at length attained when the Roman Church under John XXII., in 1334, accepted the festival and ordered it to be generally observed. The Franciscan, John Peckham, Canon of Lyons, and, from 1278 to 1292, Archbishop of Canterbury, composed a new office. The one actually in use dates from the times of Pius V.,[272] and is one of the most beautiful in the breviary, remarkable alike for sublimity of thought, depth, and elegance of form. Although the first Sunday has thus been placed in a rank by itself, the Roman rite still continues the older enumeration of the Sundays from Pentecost. In Germany and elsewhere it was the custom to reckon the Sundays from Trinity, and so each Sunday is one less than the corresponding Sunday according to the Roman enumeration. The Greeks on this Sunday commemorate All Saints, and on this account call it All Saints’ Sunday (κυριακὴ τῶν ἁγίων πάντων). 12. _Corpus Christi. The Forty Hours’ Prayer.
