I guess that when a parish refuses someone Holy Communion because she is kneeling to receive and hasn’t heard that:
The Homily should ordinarily be given by the priest celebrant himself. He may entrust it to a concelebrating priest or occasionally, according to circumstances, to the deacon, but never to a lay person.
The fraction doesn’t happen during the Consecration
If, however, the tabernacle with the Most Blessed Sacrament is present in the sanctuary, the priest, the deacon, and the other ministers genuflect when they approach the altar and when they depart from it, but not during the celebration of Mass itself.
a genuflection is made during the Creed during Christmas Mass
329. In the Dioceses of the United States of America, sacred vessels may also be made from other solid materials that, according to the common estimation in each region, are precious, for example, ebony or other hard woods, provided that such materials are suited to sacred use and do not easily break or deteriorate. This applies to all vessels which hold the hosts, such as the paten, the ciborium, the pyx, the monstrance, and other things of this kind.
the time to stand following the priest’s washing of the hands has been changed
really can’t be expected to have read this:
This Congregation for Divine Worship and the Discipline of the Sacraments has recently received reports of members of the faithful in your Diocese being refused Holy Communion unless while standing to receive, as opposed to kneeling. The reports state that such a policy has been announced to parishioners. There were possible indications that such a phenomenon might be somewhat more widespread in the Diocese, but the Congregation is unable to verify whether such is the case. This Dicastery is confident that Your Excellency will be in a position to make a more reliable determination of the matter, and these complaints in any event provide an occasion for the Congregation to communicate the manner in which it habitually addresses this matter, with a request that you make this position known to any priests who may be in need of being thus informed.
The Congregation in fact is concerned at the number of similar complaints that it has received in recent months from various places, and considers any refusal of Holy Communion to a member of the faithful on the basis of his or her kneeling posture to be a grave violation of one of the most basic rights of the Christian faithful, namely that of being assisted by their Pastors by means of the Sacraments (Codex Iuris Canonici, canon 213). In view of the law that “sacred ministers may not deny the sacraments to those who opportunely ask for them, are properly disposed and are not prohibited by law from receiving them” (canon 843 ¶ 1), there should be no such refusal to any Catholic who presents himself for Holy Communion at Mass, except in cases presenting a danger of grave scandal to other believers arising out of the person’s unrepented public sin or obstinate heresy or schism, publicly professed or declared. Even where the Congregation has approved of legislation denoting standing as the posture for Holy Communion, in accordance with the adaptations permitted to the Conferences of Bishops by the Institutio Generalis Missalis Romani n. 160, paragraph 2, it has done so with the stipulation that communicants who choose to kneel are not to be denied Holy Communion on these grounds.
The Vatican needs to do a much better job about getting the word out about liturgical changes.
