The origin of this use is doubtless to be found in the words of St. Paul (1 Corinthians 10:16); to poterion tes eulogias ho eulogoumen. But the more general use is for such objects as bread, wine etc., which it was customary to distribute after the celebration of the Divine Mysteries.
The origin of this usage can be traced back to St. Paul's words in 1 Corinthians 10:16, which refers to "eating eulogies" as a practice. This practice is also used for items like bread and wine, which were traditionally distributed after religious ceremonies.
