I am as averse to gratuitous changes in the Mass as anyone, especially those that distort or prescind from the Faith as so many ICEL translations seem designed to do. But this priest's change is not gratuitous. Though in order to uphold the authority of the Church, one may deplore any change in the approved text, doing so does not mean that the texts are what they should be. Further, one might argue that changes that bring the translation into line with the original language and meaning are essentially different from changes that yield political correctness or compliance with some other diktat of the Zeitgeist. But that does not mean it is best.
Possible translations abound for almost every word.
This too was a possible translation. But it was evidently chosen precisely in order to denigrate the Infancy Narrative by associating that narrative with unsavory elements of contemporary culture. We should rather think in terms of Providence. In this meaning the word denotes an absence of design or intention in the state of things. But not so.
