The point is, you can’t generalize that it’s either all bad or all good. I will grant you that for the “typical parish” (architecturally, especially) a screen would be/will be/ is distracting, annoying. But let me tell you I would be way more annoyed by a bishop demanding to advertise himself (his activities) during the Mass, as if the Mass is some kind of media opportunity, than I am even annoyed to watch those who used to be perfectly fine without handheld electronics suddenly stating that they absolutely cannot attend Mass without them. (Someone posted on this thread that on their large screen there’s some kind of moving/crawling message, or some news about the local bishop in giant font. There are plenty of places for bishops and other clergy to announce their own news, to publish opinion pieces and policy statements. There always have been those outlets, and those have not disappeared. Usually they’re in the local diocesan newspaper (weekly, monthly, etc.) and/or the parish bulletin – most of which are now available both in paper and electronic versions.
The situation in one of my local parishes is exceptional, if not unique. The architecture is unlike most any Catholic Church (or any Christian Church) architecture most of you have ever seen, probably. In such a vast space, a screen which completely blends in with that architecture, is illumined only during the hymns, contains only text, is not in color, and is way over to the side – not competing with the centrality of the sanctuary – and which allows everyone to look up and to be aware of what is going on, rather than fumbling with paper or books, looking down, and being preoccupied – is really a tremendous liturgical benefit relative to the smoothness of the celebration, the focus of the congregation, and, paradoxically, the silence it encourages. A side benefit is the assistance it provides to elderly people, who often have much more trouble locating a hymnal page (or who haven’t heard the page number because it was announced too softly or quickly) – not to mention reading the words.
This O.F. Mass is the most reverential Mass of any in my local area all week. Everyone attending is very clear that they are there for one purpose only, which does not include any of the personal distractions so many people busy themselves with at a “typical” O.F. Sunday Mass.
But in other settings, such as most traditional Church environments, I do not imagine it working well.
