Rite, after an invitation to the people, to which they answer "Præsta æterne omnipotens Deus," the celebrant says a prayer without a special name that corresponds to the Secret and continues at once to the memory of the saints and intercession prayer. In these other Western rites this prayer is said aloud. All the Eastern rites have prayers, now said silently, after the Great Entrance, when the gifts are brought to the altar and offered to God, but they are invariable and none of them can be exactly compared to the Roman Secret.

During the Prayer at the Bowing of Heads there may be a period of silence as all bow while the priest quietly reads the prayer.

At the Divine Liturgy, there are a number of secret prayers said by the priest, both during the litanies and during the anaphora. The primary difference between the Liturgy of Saint John Chrysostom and the Liturgy of Saint Basil the Great is the secret prayers; those of Saint Basil are longer than those of Saint John Chrysostom, and so the choir will often have to extend their chanting to cover the time.
