With reference to the first decision, it is to be remarked, how the observance of the Memoriale Rituum is inculcated, and that even in case the clerics cannot be had, the parish priest cannot celebrate a low Mass unless he gets permission to do so from the bishop each year (petita quotannis venia), and we may here observe that the only reasons which would warrant the bishop to grant permission for a low Mass on Holy Thursday, are two: first, to give an opportunity to the faithful of making their Easter Communion; and second, to give Communion to the sick. In these two circumstances the bishop can give permission for a low Mass, if he thinks it necessary, on Holy Thursday, but the parish priest, or, much less, any other priest, cannot say Mass even in these circumstances, without the permission sought and obtained every year from the bishop (venia quotannis petita). Gardellini, in a very valuable dissertation on this decree, has the following words: "Rem tamen noluit in Parochorum ruralium arbitrio relinquere, sed demandavit ut iidem quotannis et peterent et ab episcopo celebrandi veniam obtinerent". In another passage he (Gardellini) quotes the authority of Benedict XIV., who, when Archbishop of Bologna, had granted permission to some of the parish priests to say a low Mass under the circumstances above referred to, and then he adds: "Praeter parochum in sua parochia, si sacerdos aliquis cujuscumque conditionis aut dignitatis Missam privatam Feria quinta, sexta, ac Sabbato majoris hebdomodae celebrare ausus fuerit, ipsum graviter puniemus et a Divinis etiam interdicemus". With regard, however, to Holy Saturday, the case is quite different. For a private Mass cannot now be celebrated on that day without a special indult from the Holy See, as appears from a decree of the 11th March, 1690: "Firmo in reliquis remanente praedicto decreto edito die 11 Februarii nempe in Sabbato Sancto celebrationes Missarum privatarum omnino prohibentur in quibuscumque Ecclesiis et oratoriis privatis, non obstante quacumque contraria consuetudine, et unica tantum Missa Conventualis una cum officio ejusdem Sabbati sancti celebretur". Gardellini, in his dissertation already mentioned, speaking of this decree, says: "Quum autem hoc Decretum Summus Pontifex sua auctoritate firmaverit et ope typorum evulgari jusserit, vim habet legis universalis quae relaxari nequit nisi ab eo a quo lata est".
