According to S. Thomas Aquinas, the desire to engage in Communion with Christ is more important than the actual practice. There are many circumstances when actual Communion at Mass might not be possible: Infirmity, imprisonment, being stranded on a desert island or a Russian Gulag or the isolation required to prevent the spread of COVID-19 Coronavirus.
In these circumstances, intention far outweighs practical circumstances, and a Mass celebrated with Whisky and Pringles (as happened when one Bishop was at the deathbed of another Bishop) or Water and a scrap of bread in the Gulag is as valid as one celebrated in the Sistine Chapel or Westminster Abbey. If a person is unable to receive but is desirous to, then it is as good as actually receiving.
In these times of extreme measures to limit social contact and the fear of the risk of spreading the COVID-19 Coronavirus it is important to recognise the benefits of Spiritual Communion in these times of Pandemic. If you are unable to make it to Mass because you have decided to self-isolate or because you are in a high-risk category, then be assured: your desire for Communion is enough.
I wold like to go further, and offer via digital media, an opportunity to hear a Mass, even if you cannot receive via this digital medium, you can partake in a Spiritual Communion and receive the same benefits as being in Church as well as hearing the lessons and a homily. Pray along with us, be a part of a Eucharistic Digital Community and do not be excluded from the Community of the Faithful who even in these difficult times, find relationship with each other as a part of the Body of Christ as transformative.
