Dear Sirs and Madams:

I have just paid the registration fee to the Church of Satan, and now I must send my data by regular postal mail.

My question is: must I write the whole words "Church of Satan" in the envelope, or could I write just "C.o.S."?

It is for security reasons.

Yours sincerely,
H.A.
