Canon XXVIII.
Canons of Local Councils Received Ecumenically (Ancyra, Gangra, Neocaesarea, Antioch, Laodicea) · The Seven Holy Ecumenical Councils
It is not permitted to hold love feasts, as they are called, in the Lord’s Houses, or Churches, nor to eat and to spread couches in the house of God.
LocalE 5.35.2
Eusebius (H. E., Lib. IX., Cap. X.) employs the expression κυριακά in the same sense as does this canon as identical with churches. The prohibition itself, however, here given, as well as the preceding canon, proves that as early as the time of the Synod of Laodicea, many irregularities had crept into the agape. For the rest, this Synod was not in a position permanently to banish the usage from the Church; for which reason the Trullan Synod in its seventy-fourth canon repeated this rule word for word.
