Symonic heresy of the Coptic Church

Two Coptic bishops sold the Holy Spirit to the monk Matawes Antoni and paid 180,000 pounds sterling and became the Bishop of Sydney in the name of Daniel. This is a heretical heresy. The Ninth Law of the Council of Nicea, signed by the Coptic Church,
Canon 9
If any presbyters have been advanced without examination, or if upon examination they have made confession of crime, and men acting in violation of the canon have laid hands upon them, notwithstanding their confession, such the canon does not admit; for the Catholic Church requires that which is blameless.

Comments:

The examination mentioned here is not a written test, but a questioning done by other bishops.

Some of the more heinous sins (blasphemy, bigamy, heresy, idolatry, etc.) made a person uneligible for leadership in the Church. This canon says that churches have to check for these things, and that anyone who was not examined or who was wrongly ordained must be removed from office.

The argument used for such rules came from passages like Lev. 21:17-18, where God tells Moses and Aaron that no one with a blemish can approach the altar of God.
