Hanc Igitur
This prayer, like the preceding, has variations at a very few celebrations. Such occasions were once much more numerous: the Gelasian Sacramentary has as many as 38 special forms to be intercalated for all kinds of special intentions, including requiem and wedding Masses.
The normal text is: "Hanc igitur oblationem servitutis nostrae, sed et cunctae familiae tuae, quaesumus, Domine, ut placatus accipias: diesque nostros in tua pace disponas, atque ab aeterna damnatione nos eripi, et in electorum tuorum iubeas grege numerari. (Per Christum Dominum nostrum. Amen.)" (Therefore, Lord, we pray: graciously accept this oblation of our service, that of your whole family; order our days in your peace, and command that we be delivered from eternal damnation and counted among the flock of those you have chosen. )
In a concelebrated Mass, the prayer is said by the principal celebrant.
In the Tridentine Missal, the priest spreads his hands over the offerings during this prayer. This gesture was a late ceremony, occurring first in the fifteenth century, and was not adopted by the Dominicans and Carmelites. In the 1970 Roman Missal, it is during the next part of the Canon that the priest celebrating Mass, together with any concelebrating priests, performs this gesture, as at the pre-Consecration epiclesis of other Eucharistic Prayers.
