Here are Fr. Z’s recommendations:
- BE BRIEF. Make your cover letter no longer than one side of one sheet of paper.
- Avoid writing long-hand. Make it easy to read. Type or use your computer.
- Include relevant documents: Vatican dicasteries can’t act solely on the basis of Mrs. Joe Bagofdonuts’s description of events. The best thing you can do is send concrete evidence, printed. If someone wrote and distributed something, send a copy.
- If you have relevant past correspondence, such as previous responses from priests or bishops, send copies.
- Do not tell them their job! Don’t quote canons, blah blah, as if they didn’t know them already. Leave the incredibly obvious unsaid.
- Do not engage in character assassination. State FACTS with as little editorializing as possible. Blathering on and on about how “disobedient” priests or bishops are will not strengthen your case. State facts. They will know if they are disobedient.
- If you must talk about your feelings, keep it incredibly short, and do not be mean-spirited. If something made you sad or angry, okay, say it, but don’t DWELL on it. The nastier you are, the weaker your letter will be.
- At the end thank the one you are writing to for his service, and promise your prayers. And mean it.
Since you are asking for clarification on a specific topic and not writing to report an abuse, some of these would obviously not apply. I believe I read somewhere that one should use the address “Your Emminence” rather than “Dear _____”, though I can’t remember where I read it. Anyway, here’s the address:
His Eminence
Antonio Card. Canizares Llovera
Prefect of the Congregation
for Divine Worship and Discipline of the Sacraments
Palazzo delle Congregazioni
P.za Pio XII
00120 VATICAN CITY
