The Mass and the liturgy · Question 10
Is watching Mass online or on television the same as going to church?

The question: “If I concentrate better in front of a screen, haven't I met the Sunday obligation too?”
The Church's answer: A broadcast Mass is a precious help for anyone who is sick or unable to travel, letting them hear the word and join their heart to the prayer of the community, and it can help someone far away learn the liturgy as well. But a screen cannot actually stand in for the eucharistic community gathered in one place, and it cannot transmit sacramental Communion. The Church teaches plainly that in ordinary circumstances watching a broadcast is not by itself carrying out the obligation to take part in Sunday Mass.
If illness, disability, caregiving, the absence of a Mass, or another grave reason makes being there in person impossible, you may already be excused from the obligation. In that case a broadcast Mass, the Scripture of the day, and personal or family prayer are precious ways of keeping Sunday holy. Rather than treating it as a transaction — “I watched the screen, so the obligation is covered” — receive it as a help for joining the prayer of Christ and the Church from a situation you can't get out of.
If they press further: “If I say a Communion prayer in front of the screen, is that the same as receiving the Eucharist?” — the prayer of spiritual Communion is a true prayer, expressing faith in the Eucharist and longing for it, but it is not the same as sacramental Communion. Don't look down on anyone who cannot receive; where it is possible, talk with the parish about Communion for the sick or about help getting there safely in person.
In one sentence: “A broadcast Mass is a precious help in prayer for someone who can't be there, but it doesn't carry the gathered community and sacramental Communion across as they are. In ordinary circumstances, watching a screen doesn't stand in for the Sunday obligation.”
