Canon 8
That no one shall receive payments for the divine sacraments.
Whatever gift, no matter how small, of invisible grace was given, it shall absolutely not be sold for any gain of money or any other remuneration, because the Lord said [Matt 10:8]: "freely you have received, freely give". And therefore from now on whoever is established in the ecclesiastical order and receives a payment for baptizing or anointing the faithful, for the confection of chrism, or for the promotion in grade, or he receives some voluntarily offered remuneration for similar aspiration, if it was committed by the subjects with the knowledge of a bishop of the place, this bishop shall incur two months of excommunication because he covered wrongdoings known to him or did not express a necessary reproof. But if anyone of his subjects thinks that he shall receive anything in the above-mentioned cases without the knowledge of the bishop, if he is a presbyter, he shall be punished with three months of excommunication, if a deacon, with four, if a subdeacon or a cleric complied to such desires, he shall be properly whipped and duly excommunicated.
