Unity candle: in or out? The third subsection, “Preparation of Local Rituals” would seem to speak to it:
12. In addition to the faculty spoken of below in no. 17 for regions where the Roman Ritual for matrimony is used, particular rituals shall be prepared, suitable for the customs and needs of individual areas, according to the principle of art. 63b and 77 of the Constitution on the Sacred Liturgy. These are to be reviewed by the Apostolic See.
I don’t know that Rome has ever “reviewed” this ritual. What do you think its assessment would be? I probably don’t need to ask my readership, eh?
