This feast, like many others, was local before it was placed in the Roman calendar
It was not one of the feasts retained in the Pian breviary, published in 1568; but among the earliest petitions from particular churches to be allowed, as a supplement to this breviary, the canonical celebration of local feasts, was a request from Cordova in 1579 for permission to have a feast in honour of the guardian angels. (Bäumer, “Histoire du Breviaire”, II, 233.)
Bäumer, who makes this statement on the authority of original documents published by Dr. Schmid (in the “Tübinger Quartalschrift”, 1884), adds on the same authority that “Toledo sent to Rome a rich proprium and received the desired authorization for all the Offices contained in it,Valencia also obtained the approbation in February, 1582, for special Offices of the Blood of Christ and the Guardian Angels.”
So far the feast of Guardian Angels remained local. Paul V placed it (27 September, 1608) among the feasts of the generalcalendar as a double “ad libitum” (Bäumer, op. cit., II, 277). Nilles gives us more details about this step. “Paul V”, he writes, “gave an impetus to the veneration of Guardian Angels (long known in the East and West) by the authorization of a feastand proper office in their honour. At the request of Ferdinand of Austria, afterwards emperor, he made them obligatory in all regions subject to the Imperial power; to all other places he conceded them ad libitum, to be celebrated on the first available day after the Feast of the Dedication of St. Michael the Archangel.
It is believed that the new feast was intended to be a kind of supplement to the Feast of St. Michael, since the Church honoured on that day (29 September) the memory of all the angels as well as the memory of St. Michael (Nilles, “Kalendarium”, II, 502). Among the numerous changes made in the calendar by Clement X was the elevation of the Feast of Guardian Angels to the rank of an obligatory double for the whole Church to be kept on 2 October, this being the first unoccupied day after the feast of St. Michael (Nilles, op. cit., II, 503). Finally Leo XIII (5 April, 1883) favoured this feast to the extent of raising it to the rank of a double major.
Such in brief is the history of a feast which, though of comparatively recent introduction, gives the sanction of the Church’sauthority to an ancient and cherished belief. The multiplicity of feasts is in fact quite a modern development, and that theguardian angels were not honoured with a special feast in the early Church is no evidence that they were not prayed to and reverenced. There is positive testimony to the contrary (see Bareille in Dict. de Theol. Cath., s.v. Ange, col. 1220).
It is to be noted that the Feast of the Dedication of St. Michael is amongst the oldest feasts in the Calendar. There are five propercollects and prefaces assigned to this feast in the Leonine Sacramentary (seventh century) under the title “Natalis BasilicaeAngeli in Salaria” and a glance at them will show that this feast included a commemoration of the angels in general, and also recognition of their protective office and intercessory power.
In one collect God is asked to sustain those who are labouring in this world by the protecting power of his heavenly ministers (supernorum . . . . praesidiis . . . . ministrorum). In one of the prefaces, God is praised and thanked for the favour of angelic patronage (patrociniis . . . . angelorum). In the collect of the third Mass the intercessory power of saints and angels is alike appealed to (quae [oblatio] angelis tuis sanctisque precantibus et indulgentiam nobis referat et remedia procuret aeterna” (Sacramentarium Leonianum, ed. Feltoe, 107-8).
These extracts make it plain that the substantial idea which underlies the modern feast of Guardian Angels was officially expressed in the early liturgies. In the “Horologium magnum” of the Greeks there is a proper Office of Guardian Angels(Roman edition, 329-334) entitled “A supplicatory canon to man’s Guardian Angel composed by John the Monk” (Nilles, II, 503), which contains a clear expression of belief in the doctrine that a guardian angel is assigned to each individual. Thisangel is thus addressed “Since thou the power (ischyn) receivest my soul to guard, cease never to cover it with thy wings” (Nilles, II, 506).
For 2 October there is a proper Office in the Roman Breviary and a proper Mass in the Roman Missal, which contains all the choice extracts from Sacred Scripture bearing on the three-fold office of the angels, to praise God, to act as His messengers, and to watch over mortal men. “Let us praise the Lord whom the Angels praise, whom the Cherubim andSeraphim proclaim Holy, Holy, Holy” (second antiphon of Lauds). “Behold I will send my angel, who shall go before thee, and keep thee in thy journey, and bring thee into the place that I have prepared. Take notice of him, and hear his voice” (Exodus 23; capitulum ad Laudes). The Gospel of the Mass includes that pointed text from St. Matthew 18:10: “See that you despise not one of these little ones: for I say to you that their angels in heaven always see the face of my Father who is in heaven.” Although 2 October has been fixed for this feast in the Roman calendar, it is kept, by papal privilege, in Germanyand many other places on the first Sunday (computed ecclesiastically) of September, and is celebrated with specialsolemnity and generally with an octave (Nilles, II, 503)
