inistrum humerum ducit, et reducit ad
dexterum, et rursus ante pectus reducit, ibique aliquantulum sistit
quasi peracta ad omnes mundi partes cruce, eam etiam venerandam
omnibus praebet: tunc gyrum perficiens, collocat ostensorium super
altare?"

_Answer_: "Si placet, potest observare supradictum modum.... Sin
minus, servandus est modus dispositus in _Caer. Ep._, l. ii., c.
xxxiii., ubi requiritur tantummodo ut cum eodem SS. Sacramento
celebrans producat signum crucis super populum".

It is now easy to fix the ceremonies to be observed in cases where the
deacon presents the ostensorium to the priest, and receives it from him
after the benediction. First, the celebrant kneels in receiving the
Blessed Sacrament from the deacon, and the deacon, when he receives it
from the celebrant. This is a standing liturgical rule--the rubric of
the Missal for Holy Thursday says:

"Finita Missa ... fit processio.... Celebrans indutus pluviali albo
... in medio genuflexus ... accepto calice cum Sacramento de manu
diaconi stantis.... Cum autem ventum fuerit ad locum paratum
diaconus genuflexus a sacerdote stante accipit calicem cum
Sacramento".

In the _Cer. Ep._ (l. ii., c. xxiii., n. 12 et 13):

"Diaconus assistens ... capit SS. Sacramentum de altari, et illud,
stans, offert episcopo genuflexo. Cum pervenerit ad sacellum ubi
Sacramentum deponi debet ... cum erit episcopus ante supremum
gradum altaris, diaconus accipiet de manu ipsius stantis SS.
Sacramentum genuflexus".

In the rubric for the procession of Corpus Christi (ibid., c. xxxiii.,
nos. 20 et 24):

"Diaconus assistens a dexteris accedet ad altare, et cum debitis
reverentiis accipiet tabernaculum sive ostensorium cum SS.
Sacramento de altari, et illud in manibus Episcopi genuflexi
collocabit.... Postquam Episcopus pervenerit ad supremum altaris
gradum, diaconus a dextris cum debita reverentia et genuflexione
... accipiet de manu ipsius Episcopi stantis SS. Sacramentum".

Some respectable authorities allow the Blessed Sacrament to be received
by the sacred minister standing. We see no reasons in support of this
opinion. The ceremonies to be observed are the following:--The
celebrant, having received the humeral veil, ascends the altar with the
sacred ministers. The celebrant and subdeacon stop at the upper step,
and kneel on the extremity of the prede
