Canon LV.

Neither members of the priesthood nor of the clergy, nor yet laymen, may club together for drinking entertainments.

Notes.

Ancient Epitome of Canon LV.

Neither a layman nor a cleric shall celebrate a club feast.

These meals, the expenses of which were defrayed by a number clubbing together and sharing the cost, were called “symbola” by Isidore, and by Melinus and Crabbe “comissalia,” although the more ordinary form is “commensalia” or “comessalia.”  Cf. Ducange Gloss., s.v. Commensalia and Confertum.

This Canon is found in the Corpus Juris Canonici, Gratian’s Decretum, Pars I., Dist. XLIV., c. x. (Isidore’s version), and c. xij., (Martin of Braga’s version).
