The Catholic Church considers attending Mass on Sundays and Holy Days of Obligation a serious obligation for all Catholics who are able to do so. This is rooted in the Third Commandment ("Keep holy the Sabbath day") and the Church's understanding of the Eucharist as the source and summit of the Christian life.
However, the Church also recognizes that there are legitimate reasons why someone might be excused from this obligation. These include:
* Illness: If someone is sick or has a condition that makes it difficult or risky to attend Mass.
* Caregiving responsibilities: Caring for someone who is ill or unable to care for themselves.
* Other grave reasons: This could include situations where attending Mass would create an undue hardship or danger.
Ultimately, individual Catholics are expected to make a conscientious decision about attending Mass, taking into account their own circumstances and consulting with a priest or spiritual advisor if needed.
