Hmmmm!

That’s a tough one to answer since we are to be obedient to our Bishop, but the Holy See reserves the right to intepret the GIRM…
GIRM 43: “they may sit or kneel while the period of sacred silence after Communion is observed.”
** Communion Posture**
42. The gestures and posture of the priest, the deacon, and the ministers, as well as those of the people, ought to contribute to making the entire celebration resplendent with beauty and noble simplicity, so that the true and full meaning of the different parts of the celebration is evident and that the participation of all is fostered. Therefore, attention should be paid to what is determined by this General Instruction and the traditional practice of the Roman Rite and to what serves the common spiritual good of the People of God, rather than private inclination or arbitrary choice.
A common posture, to be observed by all participants, is a sign of the unity of the members of the Christian community gathered for the Sacred Liturgy: it both expresses and fosters the intention and spiritual attitude of the participants.
Code:
While the desirability of everyone in the congregation making the common gestures and postures throughout the Mass is clear (a sign of unity), recent interpretations of these norms by the Holy See provides some insight into the mind of the Church. It should be noted that the Holy See alone can authentically interpret legislation it has initiated or approved. The following was issued in response to a *dubium* of Cardinal George of Chicago. The reference is to the general posture norm, GIRM 43, and whether communicants can kneel down for their thanksgiving after Communion when everyone else is standing, however, it is clear that the mind (*mens*) of the Holy See on the role of posture is expressed. The general principle enunciated in the response would therefore also apply to GIRM 160, and the issues of kneeling to receive and genuflecting before receiving.
Congregation for Divine Worship and the Discipline of the Sacraments
5 June 2003
Prot. n. 855/03/L
**Dubium**: In many places, the faithful are accustomed to kneeling or sitting in personal prayer upon returning to their places after individually received Holy Communion during Mass. Is it the intention of the *Missale Romanum*, *editio typica tertia*, to forbid this practice?
**Responsum:** *Negative, et ad mentem*. The *mens* is that that the prescription of the *Institutio Generalis Missalis Romani*, no. 43, is intended, on one hand, to ensure within broad limits a certain uniformity of posture within the congregation for the various parts of the celebration of the Holy Mass, and on the other, to not regulate posture rigidly in such a way that those who wish to kneel or sit would no longer be free.
