Our next five sections deal with “Divine Worship.” We start off with what seems to be a curiously-worded regulation on feast days:
It belongs only to an ecumenical council or to the Apostolic See to determine, transfer or suppress feast days common to all the Eastern Churches. On the other hand, to determine, transfer or suppress the feast days of any of the individual churches is within the competence not only of the Apostolic See but also of the patriarchal or archiepiscopal synod, due regard being had to the whole area and the other individual churches.(Cfr. S. Leo M., Litt. Quod saepissime, 15 apr. 454: Petitionem autem; S. Nicephorus CP., cap. 13; Syn. Sergii Patriarchae 18 sept. 1596; can. 17; Pius VI Litt. Ap. Assueto paterne, 8 apr. 1775; etc.)
Essentially, the patriarch or synod of archbishops may make determinations on liturgical feasts as well as Rome. Any comments? Why wouldn’t this work in the West?
