Just FWIW, my wife and I were once denied Holy Communion for kneeling, very publicly and very loudly. After this, we were indeed branded “disobedient” by certain Catholics. So it’s not just what we “think” might be happening–it happens.
This is the stance taken by the CDW which has jurisdiction in this matter:
As the authority by virtue of whose recognitio the norm in question has attained the force of law, this Dicastery is competent to specify the manner in which the norm is to be understood for the sake of a proper application. Having received more than a few letters regarding this matter from different locations in the United States of America, the Congregation wishes to ensure that its position on the matter is clear.
To this end, it is perhaps useful to respond to your inquiry by repeating the content of a letter that the Congregation recently addressed to a Bishop in the United States of America from whose Diocese a number of pertinent letters had been received. The letter states: “… while this Congregation gave the recognitio to the norm desired by the Bishops’ Conference of your country that people stand for Holy Communion, this was done on the condition that communicants who choose to kneel are not to be denied Holy Communion on these grounds. Indeed,
the faithful should not be imposed upon nor accused of disobedience and of acting illicitly when they kneel to receive Holy Communion”.
Congregation de Cultu Divino et Disciplina Sacramentorum,
Prot. n. 47 / 03 / L ]
It seems very clear to me that this is not only the Holy See’s official position, it is also the position that Rome adopts in practice, including the Holy Father’s own example even in countries where standing is the norm. Let’s have it one more time:
“Indeed, the faithful should not be imposed upon nor accused of disobedience and of acting illicitly when they kneel to receive Holy Communion.”
For your edification, here is a wonderful true story, from a good friend of mine:
