3. The Memoriale Rituum requires for Holy Thursday an altar set apart from the high altar at which the ceremonies are performed, which is called the altar of repose, and which is to be decorated and adorned with the greatest pomp. There is not much difficulty in complying with this particular, which is clearly pointed out by the Rubrics of the Missal; and we may here observe that we have heard with surprise that the altar of repose on Holy Thursday in some Churches is the same as the high altar, and not distinct from it, where the ceremonies could and ought to be carried out with the greatest solemnity and accuracy. 4. The Memoriale Rituum enters into many details about the function of Good Friday and Holy Saturday, and for this latter day many things are to be procured by the parish priest which are clearly laid down in the Missal and the Memoriale so often referred to. We deem it unnecessary to mention all the details, particularly as while we are writing on these subjects we have been favoured with a copy of a letter of his Grace the Archbishop of Dublin to the clergy of his diocese, which we annex here as confirming our views on these points, and also as a summary of what we have been stating in this article. PAULUS, _Dei et Apostolicae sedis gratia, Archiepiscopus Dublinensis, etc., Venerabili Clero Dublinensi Tam Saeculari quam Regulari_. Maximi momenti esse ut leges ecclesiasticae ad sacras caeremonias peragendas spectent, accuratissime observentur, nemo est qui ignoret. Itaque, cum Nobis relatum fuerit in quibusdum hujus dioecesis Ecclesiis quasdam leges rituales praecipue ad hebdomadam sanctam spectantes, diversam et variam interpretationem accipere, adeoque in omnibus eandem disciplinam non vigere, cum que maximopere optandum sit ut non tantum idem spiritus sed et eadem agendi ratio ubique servetur, nostrim uneris esse existimavimus pauca quaedam que ad unitatem promovendam opportuna videntur, in omnium memoriam revocare, non quasi nova aliqua decernentes, sed eo tantum fine ut quam accuratissime Ecclesiae leges jam latae observentur. Haec vero sunt quae ab omnibus servari volumus:-- 1mo. In oratoriis domesticis, missa celebranda non est in Feria Quinta in Coena Domini, neque in duobus sequentibus diebus, neque in die Paschatis. 2do. In Feria quinta praedicta, unica tantum celebrandi est Missa in singulis Ecclesiis, quae solemnis aut conventualis esse debet. In ea vero Missa clerus qui ad ecclesiam spectat, Communionem inter Missarum solemnia a manu celebrantis recipere debet, juxta veterem et constantem Ecclesiae usum. 3tio. Altare in quo reponendum est SS. Sacramentum, quod Feria Sexta in Missa Praesanctificatorum sumi debet a celebrante, omni cura ornandum est. Caeterum, Sacra Hostia includenda est in capsula, seu in sepulchro, ut vulgo dicitur, quod clave a sacerdote custodienda claudi debet, nec licet sacram Hostiam ita exponere ut videatur a fidelibus.
