From a priest…
A devout Catholic couple would like to get married using the EF vows (in English), but would like to have an Ordinary Form Latin Mass. Could I do their vows in the EF outside of Mass, and then celebrate a non-wedding Mass in the OF?
As much as I am a proponent of using as much of the Extraordinary Form as possible, it seems to me that in this situation, you should choose one or the other. Do the whole thing, either in the EF or in the OF.
If you want, you can have the whole of the Ordinary Form in Latin or in English, ad orientem with vestments that please and Gregorian chant, etc.
That said, it is possible to do the Extraordinary nuptial rites outside of Mass as you find them in the Ritual (with the nuptial blessing, etc.) and, then, after an – at least – logical (if not chronological) break, launch into a Mass in the Ordinary Form.
However, that still seems to me to be a less than optimal option, provoking questions that devolve into needless explanations. If the marriage rite, then why not the Mass too? Etc.
I am not sure about the reasoning behind such a collision of the rites. Perhaps this needs to be thought through a bit more.
