St. John Chrysostom, Instructions to the partaker of the Holy Mysteries

St. John Chrysostom complained bitterly in his conversations that many communicants left the church before the end of the liturgy: they barely received the Holy Eucharist when they hurried home, without having heard the hymns and prayers of thanksgiving for the communion of the Holy Mysteries in church. "Would you like me to tell you," says the Archbishop of Constantinople, "whose work do those who leave before the end, without having performed the hymns of thanksgiving at the end of the meal resemble? It may seem cruel of me to say this, but it must be said because of the carelessness of many. Judas, having partaken of the last supper that last night, went out hastily, while all the others were still reclining. These are the imitators of those who go out before the last thanksgiving."
