The Canons of the Council in Trullo; Often Called The Quinisext Council 99Canon XCIX.

We have further learned that, in the regions of the Armenians, certain persons boil joints of meat within the sanctuary and offer portions to the priests, distributing it after the Jewish fashion. Wherefore, that we may keep the church undefiled, we decree that it is not lawful for any priest to seize the separate portions of flesh meat from those who offer them, but they are to be content with what he that offers pleases to give them; and further we decree that such offering be made outside the church. And if any one does not thus, let him be cut off.
