The point during the Liturgy of the Eucharist when the bread and wine are transformed into the Body and Blood of Christ.
At the consecration, servers should be kneeling with heads bowed. After the words of consecration, when the celebrant elevates the Precious Body and Precious Blood, servers should raise their heads to adore the Blessed Sacrament and sign the cross.
At the final genuflection after the elevation of the chalice, the acolyte should rise with the celebrant.
WHO the day before he suffered, took bread into his holy and venerable hands,
and with eyes lifted up to heaven, unto thee, God, his almighty father, giving thanks to thee, he blessed, broke and gave it to his disciples, saying:
TAKE THIS, ALL OF YOU, AND EAT OF IT:
FOR THIS IS MY BODY,
WHICH WILL BE GIVEN UP FOR YOU.
LIKEWISE, after supper,
taking also this goodly chalice into his holy and venerable hands, again giving thanks to thee, he blessed, and gave it to his disciples, saying:
TAKE THIS, ALL OF YOU, AND DRINK FROM IT,
FOR THIS IS THE CHALICE OF MY BLOOD,
THE BLOOD OF THE NEW AND ETERNAL COVENANT,
WHICH WILL BE POURED OUT FOR YOU AND FOR MANY
FOR THE FORGIVENESS OF SINS.
DO THIS IN MEMORY OF ME.
