Ps. xxxiv. 9. In the Apostolic Constitutions the “Sancta Sanctis” and its response are immediately followed by the “Gloria in excelsis,” and the “Hosanna.” Then the Clergy partake, and there follows a direction that this Psalm xxxiv. is to be said while all the rest are partaking. In the Liturgy of Constantinople there is the direction: “The Choir sings the communion antiphon (τὸ κοινωνικόν) of the day or the saint.”
