From a reader:
Our new pastor recently published a letter in the bulletin [I've cut that out in order to "anonymize" this.] in which he uses the GIRM [General Instruction on the Roman Missal] to argue that those who genuflect before or kneel while receiving Holy Communion do so incorrectly or, at least implicitly, in a spirit of disobedience. He seems to emphasize “avoiding private inclinations” while ignoring “the traditional practice of the Roman Rite”, and he also seems to overemphasize the idea of being in Communion with each other to the detriment of being in Communion with Christ. His pushy attitude really does not sit well with me. But this instance does raise the question: Is the GIRM defective to some degree, or is this just a poor interpretation of it? As for me, this just makes me more obstinate in my desire to be that stubborn, ‘disobedient’ guy who kneels for Communion.
His citation (in the letter to which I did not link) of GIRM 160 is to point, but I think the norm is descriptive rather than prescriptive.
The norm is that Holy Communion is received standing, but Holy Communion will not be denied to those who kneel. Father describes his opinion about why we should all receive Holy Communion in exactly the same way (Jawohl!).
Think of it this way. Let’s say that I have a preference for green vestments that are a robust forest green. As a matter of fact, I think all priests should wear vestments of that shade of green rather than the other 50 shades of green. Furthermore, I don’t think they should even want to wear apple, chartreuse, or lime green. They should conform to my will. My hypothetical opinion on forest green is, however, just my opinion. It is not the law. The law requires “green”.
“But Father! But Father!”, some of you may be saying, “Are there norms for receiving Communion?”
For reception of Holy Communion, the law requires that the faithful be in a state of grace, free from any canonical penalty, and not persisting in manifest grave sin (see Canon 915).
Perhaps it would be better for parish priests to be first and foremost vigilant about observing those norms before they start imposing their personal preference about uniformity of posture.
