A
Canon XXXIV.
The Quinisext Council in Trullo (692) · The Seven Holy Ecumenical Councils
But in future, since the priestly canon openly sets this forth, that the crime of conspiracy or secret society is forbidden by external laws, but much more ought it to be prohibited in the Church; we also hasten to observe that if any clerics or monks are found either conspiring or entering secret societies, or devising anything against bishops or clergymen, they shall be altogether deprived of their rank.
Trull 1.35.2
If clerics or monks enter into conspiracies or fraternities, or plots against the bishop or their fellow clerics, they shall be cast out of their grade.
