I read an article on liturgical absues from
ourladyswarriors.com yesterday.
According to them, there are only four abuses that invalidate the Mass:
- If the person consecrating the Host is not a male, legitimately ordained priest - this includes when the lay congregation “co-consecrates” the Eucharist with the priest
,
- If the priests uses anything but unleavened wheat bread or grape wine (or low-gluten bread and mustum for wheat allergies and alcoholism respectively),
- If the priest does not say the words “This is my Body…This is my Blood…Do this in memory of me”, and therefore does not say the words Christ did,
- This surprised me: If the priest does not INTEND to turn the Bread and Wine into the Body and Blood, it does not become Christ’s Body and Blood.
These are the only liturgical abuses that invalidate a Mass. The rest are illegal, but do not put in jeopardy your right to the consecrated Host. They do, however, give less reverence to the Mass than is right and proper.

This is fairly correct. There is also an exception to #2. If the priest uses wheat bread that is leavened, the mass is valid and can be licit in some situations, but most of the time it’s not licit. I’m remembering those priests in prison under the Nazis and Communists who had to celebrate mass in their cells with a piece of bread from their meal. One of them being St. Maximilian Kolbe. The friars who were in prison with him did say that he would celebrate mass for them with regular table bread or whatever they call table bread in a concentration camp.

There is also a famous Vietnamese Cardinal whose name escapes me right now. He too was in prison for many years and he tells how he would save a piece of bread from his meal and when he could get even a drop of wine, he would consecrate them. These masses are valid and licit.
It is not invalid to use leavened bread. It is the tradition of the Latin Church. Not is not a universal tradition. If it were invalid, none of the Catholic Churches would be able to use leavened bread. In the Latin Church it would be ilicit to do so. However, ilicit means illegal. The Church does not apply this law to situations such as the ones mentioned above.
**Can. 924 §1. The most holy eucharistic sacrifice must be offered with bread and with wine in which a little water must be mixed.
§2. The bread must be only wheat and recently made so that there is no danger of spoiling.
§3. The wine must be natural from the fruit of the vine and not spoiled.
Can. 926 According to the ancient tradition of the Latin Church, the priest is to use unleavened bread in the eucharistic celebration whenever he offers it.**
There is an exception to #3. The Anaphora of Addai and Mari does not contain the words of institution, but the meaning of the Eucharist and the intent to consecrate it there. The Chaldean Catholics are allowed to use it as it is. In some places the insert the words of institution and in other places they do not. The Church allows them to do either. Bl. John Paul II decreed that the words of the institution of the Eucharist are in fact present in a euchological and disseminated manner.
The article is not precise in its terms. It is better to use the Code of Canon Law for the Latin Church and the Code of Canon Law for the Oriental Churches than to use internet articles, unless they are by legitimate Catholic sources.
The minute you see words such as “abuse, modernist, modernism” you can be sure that the writer is not an authorized Catholic writer. The Church does not use such language in her delivery. The Church’s delivery is always very matter of fact and the language is usually very legal or very philosophical when it comes to such matters. For example the term “euchological” is a perfect example of philosophical language to explain why this particular anaphora is valid. She rarely uses the common man’s rhetoric. Those signs should send red flags that the writer has an agenda or is angry about something.
Be careful with such writings. Read them for your information, but verify with authoritative Catholic resources. At the end of the day, the the Sacred Congregation for the Faith said in an interview last week, the final word always rests with the pope and those whom he delegates, not with us or anyone else. Only the pope or his delegates can authoritatively interpret Sacred Tradition. Even in delegation, there are limits that the papacy places on Prefects and Presidents.
