Ecclesiastical crime is the term used to refer to crimes (Delictum) related to the clergy where the crime is against canon law. Compare Civil law.
The crime of Simony is the ecclesiastical crime of paying for offices or positions in the hierarchy of a church. The crimes of Schism and Heresy are also ecclesiastical crimes.
Older examples include "perjury", the breaking of a promissory oath (contractual promises made by oath or pledge of faith), and this was treated as an ecclesiastical crime. Some crimes have or have had both an ecclesiastical and a civil element to the crime; suicide and witches are counted here.
Financial and donation related
The term is also specifically used today for misappropriation of donation monies. In the International Bulletin of Missionary Research, January 2009, David B. Barrett, Todd M.

Unchecked this crime will be valued at USD$65 Billion by 2025
