The General Instruction to the Roman Calendar states: “Christ’s saving work is celebrated in sacred memory by the Church on fixed days throughout the year. Each week, on the day called the Lord’s Day, the Church commemorates the Lord’s resurrection. Once a year at Easter the Church honors this resurrection and passion with the utmost solemnity. In fact, through the yearly cycle the Church unfolds the entire mystery of Christ and keeps the anniversaries of the saints.”
This calendar is based upon the Roman Calendar, promulgated by Pope Paul VI on 14 February 1969, and subsequently amended by Pope John Paul II, and the Particular Calendar of the Canons Regular of the Order of the Holy Cross, approved 6 February 1974 by the Sacred Congregation for Divine Rites.
The Ordo is the Liturgical Calendar of the Church according to a given calendar year. So, the Crosier Liturgical Ordo contains a listing of what should be celebrated on a particular day (e.g. ferial, feast), and it also lists the liturgical rank and color of the day, together with the liturgical readings and specific rituals to be observed in the celebration of the Eucharist and the Liturgy of the Hours.
Accompanying the Crosier Liturgical Calendar or Ordo are proper liturgical texts and adaptations for the celebration of the feasts and memorials of the respective religious family. The Crosiers have used proper liturgical texts throughout their 800 years of religious life. Proper liturgical texts for the Eucharist and the Liturgy of the Hours are currently available in most of the languages used in the Order. These texts and adaptations should be available in each community for the celebration of the conventual liturgy. They are also most likely available from the Order’s province and general offices. They may also be available, along with this calendar and other liturgical resources on the Generalate website[ oscgeneral.org ] under “Liturgical Resources”.
In this calendar, the liturgical readings from the Proper of Seasons and Proper of the Saints have been used for all solemnities and all feasts since they must take the place of the weekday readings for those respective days. The readings from the current year’s weekday cycle generally have been used on days on which a memorial or optional memorial of a saint occurs. The exceptions to this rule are the memorials or optional memorials which have proper readings (usually only the Gospel) assigned to them in the Lectionary for Mass. These readings are marked with an asterisk (*) and should normally be used on those days. Substitutions from the Common of Saints may be made for the other readings suggested for those memorials or optional memorials (See the Introduction to the Lectionary for Mass, number 83). Optional memorials are designated by brackets.
