A Mass intention is the Church’s way of applying the spiritual fruits of the Eucharist to a specific person or intention. Every Mass is offered for the whole Church, but the priest may also offer that particular celebration for:

• A deceased loved one
• A living person (birthday, anniversary, illness, thanksgiving)
• A special intention (conversion, healing, gratitude, vocations)

This practice is ancient. The early Church prayed for the living and the dead during the Eucharist, and inscriptions in the Roman catacombs show Christians asking that the Mass be offered for the repose of souls. Saints like Augustine, Monica, Ambrose, and Chrysostom all testify to the power of these prayers. 

The Church teaches that the Mass is the most powerful prayer we can offer. When a Mass is celebrated for someone, special graces are applied to that person or intention in a unique way. 

Mass intentions are governed by Canons 945–958, which regulate how intentions and offerings are handled. Key principles include:

1. One Intention per Mass (Normally)

Canon Law allows one intention per Mass, unless the faithful explicitly consent to a “collective intention” Mass—multiple intentions combined into one celebration. Consent cannot be presumed. 

2. Offerings Are Not Payments

A stipend is a freewill offering, not a fee. It supports the priest and the parish, but grace cannot be bought. The Church condemns simony and requires transparency. 

3. Intentions Must Be Compatible with Catholic Teaching

Parishes may not accept intentions that contradict the faith or moral teaching. 

4. Accurate Record‑Keeping

Priests and parishes must keep careful records of intentions, stipends, and fulfilled Masses. 

5. Surplus Intentions May Be Sent to Mission Priests

If a parish cannot schedule all intentions within a year, they may be forwarded to priests in mission territories who can offer them sooner. 

6. Some Masses Cannot Take Individual Intentions

Certain liturgies—such as Holy Thursday, Easter, Christmas, Mother’s Day, Father’s Day, and All Souls—are offered for all parishioners and do not take individual intentions. 

• The repose of the soul of someone who has died
• A living person who is sick or suffering
• A birthday, anniversary, or milestone
• Thanksgiving to God
• A general prayer intention (as long as it aligns with Catholic teaching)
