Salmi 118:63

Partaker. Hebrew, "a friend." I do not fear to approve of their conduct, (Calmet) and condole with them. (St. Hilary) --- The true living members of Christ enjoy the great benefit of partaking in the prayers and good works of the whole Church militant and triumphant, in the communion of saints. (Worthington) --- See St. Augustine, Confessions iv. 4.
