Is it a Mortal Sin to Miss Mass?

Must I go to confession if I miss Mass without a good reason? Can I still receive the Eucharist?

Dear O,

Yes, it is a mortal sin to deliberately miss Sunday Mass when one could have atteded and chose not to. Yes, you must go to Confession first before receiving Holy Communion.

Pray for a greater appreciation for what the Mass. It is the celebration of His Passion, Death and Resurrection. There is nothing that happens on this earth to equal it.

Fr. Vincent Serpa, O.P.
