I use my iPad or iPhone for the Liturgy of the Hours when I pray it privately or informally with others.
I despise when these are used for formal recitation or chanting in a church, oratory or chapel setting, especially if the Presider uses it.
I am horrified by the use of these for Mass and on the altar and I think the laity using these devises to participate at Mass makes people think they are texting or watching something inappropriate in a Church setting.
The liturgical books of the Church, especially the Liturgy of the Hours and the Roman Missals are sacramental and should be treated with dignity and only for sacred use.
What do you think?
