I don’t know how deeply the word will spread. Many parishes do not sing an acclamation at all, though the Church cites such singing as “appropriate.” A total of 21 acclamations are listed at nos. 225-245 at the Order of Baptism of Children. Many are short enough for a quick intonation followed by the singing of all present.
I’ve found Gospel Acclamations useful, especially when I’ve been called upon to offer music at an unfamiliar parish or a new location. With so many unchurched people attending a baptism, especially outside of Mass, it seems something conveniently easy and known has been a good thing.
Often, I use one of the longer acclamation texts as a verse between the first and second singing of the people’s alleluia.
So, a good thing to omit the alleluia? Does it matter much or little?
