Well, I did a bit of research, and here’s some information (in case someone else out there is wondering about these issues):
Yes, it is the standard practice, worldwide, to stand for most of the Eucharistic prayer. That is the general rule, and a country needs a dispensation for additional kneeling. The general, worldwide rule is also for people to kneel during the consecration itself, then resume standing for the rest of Mass, not to stand during the consecration.
The bishops of America sought and obtained permission to require kneeling not just at the consecration but through to the Great Amen, and that is the rule here. Liturgical practices that apply to other parts of the world do not subvert the liturgical law that the Vatican and the American bishops have hammered out for this country.
So that’s one answer. I wish the article would cite the sources! Here’s another, with some better citation:
The law on the posture of the people is as follows:
1. Universal Law. The General Instruction on the Roman Missal #43 establishes as the universal norm of the Roman Rite the practice of kneeling for the Consecration. This is understood to mean from the Epiclesis (the prayer calling for the sending down of the Holy Spirit) to the Mysterium Fidei (The Mystery of Faith).
So, it appears that the CA article above is consistent with this post. In most countries, they kneel until the Mystery of Faith; but here in the US, we kneel all the way through to the Great Amen.
2. American Particular Law. The U.S. Bishops adapted the universal norm with Roman approval, retaining the practice of kneeling from after the Sanctus (Holy, Holy, Holy) to the Doxology (Through Him, with Him, in Him), in other words for the entire Eucharistic Prayer. Thus, while in Italy and many other places they stand until the Consecration, at which time they kneel down for the Consecration, in the US we have knelt for the Canon in the past and continue to do so.
And then it cites:
The U.S. version of the General Instruction n. 43 therefore reads,
43 … ** In the dioceses of the United States of America, they should kneel beginning after the singing or recitation of the Sanctus until after the Amen of the Eucharistic Prayer, **except when prevented on occasion by reasons of health, lack of space, the large number of people present, or some other good reason. Those who do not kneel ought to make a profound bow when the priest genuflects after the consecration.
These sound like the exceptions that otjm may have been referring to. And finally:
Local norms. Since the law governing adapting the norms to a particular church (diocese) or nation are spelled out in the General Instruction, and require obtaining Roman approval before implementation, the existence of an adaptation departing from the norm for the US, such as standing for the Consecration, is easily verified: a Roman document granting approval.
Hm. Maybe my parish has a special document from Rome? I kind of doubt it…
Finally, this guy says something slightly different:
Q. 1. Should I stand or kneel during the Consecration of the bread and wine into the Body and Blood of Christ?
A. 1. Unless specific instruction has been given by the Bishop of your diocese to stand, the proper thing to do is to kneel during the Consecration.
That seems to imply that each diocese can determine the rule, not Rome.
