Literally, “at the thanksgiving,” or “eucharist.” Massuet, the Benedictine editor, refers this to the Lord’s Supper, and hence concludes that some of the ancient liturgies still extant must even then have been in use. Harvey and others, however, deny that there is any necessity for supposing the Holy Eucharist to be referred to; the ancient Latin version translates in the plural, “in gratiarum actionibus.”
