It was not until a late date that the first Sunday after Pentecost was raised to a higher rank, for in the Gregorian Sacramentary it has no special name, while in the Gelasian Sacramentary, and in the appendixes to the Gregorian,[265] it is called merely the Sunday after the octave of Pentecost, or the Sunday after Pentecost. In the Latin Church, it is now a festival devoted to the honour of the Most Holy Trinity. Concerning the introduction of this new feast into the Church’s year, we learn from the Micrologus that, the Sunday after Pentecost being a _dominica vacans_ without any special office of its own, many used on this day the office of the Trinity drawn up by Bishop Stephen of Liège (903-20). When Pope Alexander II. († 1073) was questioned on the point, he replied that it was not the Roman custom to set apart any particular day in honour of the Holy Trinity, since the Trinity was honoured every day by the _Gloria Patri_ in the psalmody. It is to be noted, continues the Micrologus,[266] that Alcuin, at the request of the Saint Boniface, composed a Mass in honour of the Holy Trinity. Binterim speaks sarcastically of this reference, because Boniface had died long before the time when Alcuin flourished. The reference is not to be passed over on this account, for the mistake arose merely from a misunderstanding. Alcuin had put together from the missal employed in his Abbey Church a number of Masses—votive Masses, as they would now be called—for each day of the week, to be used under certain conditions, and to these was added, amongst others, a Mass in honour of St Boniface for the monks of Fulda.[267] This explains the misunderstanding in the Micrologus. Alcuin had also arranged a collection of prayers drawn from the Gregorian Sacramentary to form a prayer-book. This, by itself, enables us now to appreciate Alcuin’s share in the matter.[268] It merely means that he recommended the Mass of the Trinity should be said on Sundays, in case a priest had not a complete missal, or through ignorance was unable to use it properly.
