Of Doubles, (fo called because the Anthems are repeated entire both before and after the Pfalms at Vefpers) fome are of the firft Clafs, marked thus in the Calendar, D. 1 Cl. others of the second Class, and are marked thus, D. 2 Cl. others are greater Doubles, marked with a capital D. others Common Doubles, marked with a common d. 2. Doubles are always kept on the day marked in the Calendar, unless they chance to fall on fome Sunday of the firft Clafs, fome privileged Feria, or within certain Octaves, which take place of the Festivals: In which cafe they are transferred to the first day not taken up with a Double or Semidouble. The Sundays of the firft Clafs, which take place of all Doubles whatsoever, are, The first Sunday of Advent; the first Sunday of Lent; Paffion-Sunday; Palm-Sunday; Eafter-Sunday; Low-Sunday; Whitfunday; Trinity-Sunday. The Sundays of the fecond Clafs, which take place allo of all Doubles, except thofe of the first Class, and of which, in that cafe, a Commemoration is made at Mafs and in both Vefpers, are, the Second, Third, and Fourth of Advent; Septuagefima, Sexagefima, and Quinquagefima; the Second, Third, and Fourth of Lent. The Ferias, which enjoy the fame privilege as Sundays of the first Class, are, Afb-Wednesday; all A 2 Holy Holy-Week; Whitfun-Eve; the whole Octaves of Eafter and Whitfuntide. In like manner, within the Octave of the Epiphany, no feaft lefs than a firft Class can be kept. On all other Sundays of the year, if a Double chance to occur, it is kept with a Commemoration of the Sunday at Mafs, and at Vefpers too, except the following day be a feaft of the first Class. 3. A Semidouble (fo called because only part of the Anthem is faid before each Pfalm at Vefpers) is marked in the Calendar thus, fem. and occurring on any Sunday whatsoever, is put off to the first vacant day; that is, the firft day on which there is neither Double nor Semidouble marked in the Calendar. The fame is to be obferved with regard to all Semidoubles occurring within the Octave of Corpus Chrifti. 4. Simples have no mark in the Calendar, and are never transferred; but if they fall on a Sunday, or on any other day, when the office cannot be faid of them, a Commemoration is made at the first Vefpers, and at Mass; unless it be a Feast of the first Glafs, (on which no notice is taken of Simples) or of the fecond Clafs, in which cafe a Commemoration of them is made in the first Vefpers, and at Low Mafs only. 5. The following Ferias, called Greater Ferias, take place of all Simples, and there is only a Commemoration made of them at Mafs, viz. the Ferias of Advent and of Lent, the Ember-Days, Tuesday in Rogation-Week. A Commemoration is alfo made of the Ferias of Advent and Lent at Vefpers and Mass, whatever feaft happens; but, of the Ember-Days and Tuesday in Rogation-Week, only at Mass. 6. If a Vigil happens within an Octave, the Mafs is of the Vigil with a Commemoration of the Octave, unless there be a Double or Semidouble feast that day; in which case the Mafs is of the feaft with a Com memoration memoration of the Octave and of the Vigil: But if a Vigil occur on a feaft of the first Class, there is no Commemoration made of it. If a Festival, that hath a Vigil, fall on a Monday, the Mafs of the Vigil is faid on the foregoing Saturday, except the Vigil of Christmas and of the Epiphang. If a Vigil happen in Advent, the Mass is of the Vigil with a Commemoration of the Feria, except the Vigil of Christmas. If a Vigil happen in Lent, or on an Ember-Day, the Mafs is of the Feria with the Commemoration of the Vigil. In the Pafchal-time there is no office of a Vigil, except that of the Afcenfion-Eve, which however is no faft. 7. When a Double of the first or fecond Clafs (which is a holiday of obligation, printed in the Calendar in CAPITALS) falling on any day, is to be transferred, the obligation of the holiday is never transferred, but the faithful are obliged to affift at Mafs on the day marked in the Calendar. 8. When feveral feftivals have been tranflated from their proper days, they are afterwards to be kept in this order: First thofe that are Doubles, and then thofe that are Semidoubles; and among the Doubles or Semidoubles, thofe, whofe proper days first occurred, are to be kept first. 9. Upon all Doubles one COLLECT, SECRET, and POSTCOMMUNION only is faid; except it happens on a Sunday, or within fome Octave, or upon fome Vigil, or in the time of Lent or Advent, or except it occurs with fome Simple: In all which cafes two COLLECTS, &c. are faid; one of the Double, the other of the Sunday, O&ave, &c. 10. Upon Sundays and all Semidoubles are faid three COLLECTS, SECRETS, and PosтCOMMUNIONS; excepting Sundays, which occur within an A 3 Oc |
