General Roman Calendar of Pope Pius XII

In 1955, Pope Pius XII made several changes to the General Roman Calendar of 1954; those changes remained in force until 1960, when Pope John XXIII decreed a new revision of the General Roman Calendar (see General Roman Calendar of 1960). The changes made by Pope Pius XII thus remained unaltered for only five years.

Pius XII made those changes by the decree "Cum nostra hac aetate" of 23 March 1955. ^[1]

The General Calendar of Pope Pius XII is not authorized for liturgical use by traditional groups in communion with the Holy See, and most sedevacantists prefer to use the General Roman Calendar of 1954, ^{[2] [3] [4] [5]} as well as Old Roman Catholics, as their members consider it to be the last calendar untainted by the revisions that began in 1955. However, a few sedevacantists do observe the revisions beginning in 1955, while excluding those of the John XXIII, such as the Congregation of Mary Immaculate Queen. ^{[6] [7]} The celebrations including the revisions according to General Roman Calendar of Pope Pius XII starting in 1955 are listed here below. ^{[8] [9]}

Changes to the Calendar

Rank of feasts

The grade and rite of "Semi-Double" was suppressed, and the liturgical days formerly celebrated as that rite were to be celebrated in the simple rite except the Vigil of Pentecost which was raised to the double rite. ^[10]

Sundays

The Sundays of Advent and Lent and those that follow up to Low Sunday, and also Pentecost Sunday, were to be celebrated as doubles of the first class, outranking all feasts; but when feasts of the first class occurred on the second, third or fourth Sunday of Advent, Masses of the feast were permitted except the conventual Mass. Sundays previously celebrated in the Semi-Double rite were raised to the Double rite. An impeded Sunday Office and Mass was to be neither anticipated nor resumed. A feast or title or any mystery of Our Lord falling on a Sunday per annum was thenceforth to take the place of the Sunday, with the latter merely commemorated. ^[11]

Vigils

The Vigil of the Nativity of the Lord and the vigil of Pentecost were privileged vigils. The Vigils of the Ascension of Our Lord, the Assumption of the Blessed Virgin Mary, Saint John the Baptist, Saints Peter and Paul and Saint Lawrence were to be common vigils and, if they occurred on a Sunday, were not to be anticipated, but simply omitted. All other vigils, including those marked in particular calendars, were suppressed. ^[12]

Octaves

Only the Octaves of Easter, Christmas and Pentecost were to be celebrated; all others occurring either in the universal or in particular calendars were suppressed. The days within the Easter and Pentecost octaves were raised to the Double rite, had precedence over all feasts, and did not admit commemorations. But the days of the Octave of Christmas, although of the Double rite, continued to be celebrated as before. ^[13]

From 2 to 5 January, unless some feast occurred, the Office was to be of the current feria in the simple rite. The Mass was to be the same as that of 1 January but without the Credo and the special "Communicantes". ^[14]

With the suppression of the Octave of Epiphany, the days from 7 to 12 January became feriae per annum (in the Simple rite); up to the Sunday following Epiphany, the Mass was to be the same as that of the Epiphany, but without the Credo and without the special "Communicantes"; after the Sunday, the mass was to be that of the Sunday (which on that Sunday itself remained continually impeded by the Feast of the Holy Family). On 13 January the Commemoration of the Baptism of our Lord was to be celebrated in the major double rite, using for the Office and the Mass those previously said on the Octave of the Epiphany. But if 13 January occurred on Sunday, the Office and Mass were to be those of the "Feast of the Holy Family" without any commemoration of the Baptism of Our Lord. ^[15]

The days from the Ascension of Our Lord to the Vigil of Pentecost exclusive became feriae of Eastertide (in the Simple rite); the Mass was to be that of the Feast of the Ascension, but without the Credo and the special Communicantes (even on the Friday before Pentecost, where hitherto the Mass of the Sunday had to be taken). The days of the suppressed Octaves of Corpus Christi and the Most Sacred Heart of Jesus became feriae per annum. ^[16]

Feasts of the Saints

Saints' feasts previously celebrated in the Semi-Double rite were to be treated as Simple feasts, and those previously celebrated in the Simple rite were reduced to a commemoration. If any feast not of the first or second class occurred on the ferias of Lent and Passiontide, from Ash Wednesday to the Saturday before Palm Sunday, the Office (if recited privately) and the Mass could be either of the feria or of the feast. ^[17]

Changes related to St. Joseph and others

By a separate decree of the same year 1955, Pope Pius XII instituted the feast of "Saint Joseph the Worker" on 1 May (moving the feast of "Saints Philip and James Apostles" from 1 May, where it had been since the sixth century, to 11 May, and suppressing the "Solemnity of Saint Joseph, Spouse of the Blessed Virgin Mary" that, since Pope Pius IX's decree of 10 September 1847, had been celebrated on the second Wednesday after the Octave of Easter). ^[18]

Moveable feasts

The moveable feasts are those connected with the Easter cycle, and Easter is the date relative to which their position is ultimately determined. The date of Easter is determined relative to the lunar calendar as used by the Hebrews. The rule has since the Middle Ages been phrased as "Easter is observed on the Sunday after the first full moon on or after the day of the vernal equinox." However, this does not reflect the actual ecclesiastical rules precisely. One reason for this is that the full moon involved (called the Paschal full moon) is not an astronomical full moon, but an ecclesiastical moon. Another difference is that the astronomical vernal equinox is a natural astronomical phenomenon, which can fall on 20 or 21 March, while the ecclesiastical vernal equinox is a fixed March 21 (on the Gregorian calendar). Easter is determined from tables which determine Easter based on the ecclesiastical rules described above, which do not always coincide with the astronomical full moon. The moveable feasts are given below:

Septuagesima Sunday (9th Sunday before Easter)
Sexagesima Sunday (8th Sunday before Easter)
Quinquagesima Sunday (7th Sunday before Easter)
Ash Wednesday (Wednesday after Quinquagesima Sunday)
Passion Sunday (Sunday 2 weeks before Easter)
Feast of the Seven Sorrows of the Virgin Mary (Friday after 2nd Sunday before Easter)
Palm Sunday (Sunday before Easter)
Holy Thursday (Thursday before Easter)
Good Friday (Friday before Easter)
Holy Saturday (Saturday before Easter)
Easter Sunday, the Solemnity of Solemnities, the Resurrection of Our Lord Jesus Christ
Low Sunday (Sunday after Easter)
The Lesser Litanies at St. Mary Major (Monday after the 5th Sunday after Easter)
The Lesser Litanies at St. John Lateran (Tuesday after the 5th Sunday after Easter)
The Vigil of the Ascension of our Lord Jesus Christ and the Lesser Litanies at St. Peter's (Wednesday after the 5th Sunday after Easter)
The Ascension (Thursday after the 5th Sunday after Easter)
The Vigil of Pentecost (Saturday after the 6th Sunday after Easter)
Pentecost (7th Sunday after Easter)
Holy Trinity and the Octave of Pentecost (8th Sunday after Easter)
Corpus Christi (Thursday after the 8th Sunday after Easter)
Sacred Heart of Jesus (Friday after the 9th Sunday after Easter)

The 1955 calendar assigned special celebrations also to the days within the Octaves of Easter and Pentecost, as to the days within the Octave of Christmas.

20. It is perhaps unclear when the identification of the Saint Felix of 29 July with Antipope Felix II was abandoned. The identification is still found in the 1920 typical edition of the Roman Missal, with feasts updated to the late 1920s Archived 2020-03-01 at the Wayback Machine , but does not appear in the 1962 typical edition, which calls him simply a martyr (see General Roman Calendar of 1960). The 1952 Marietti printing of the Missal, which precedes 1955, the reference year for this article, also omits the numeral "II" and the word "Papae", however, the 1952 Pustet and the 1956 Typis Polyglottis Vaticanis printings of the Breviary still list Felix as a Pope and with the numeral II. The baselessness of the identification was recognized long before: in its 1909 article on Felix II the Catholic Encyclopedia referred to this identification as a "distortion of the true facts".
