But we ARE in the Western Rite, and therefore without the cultural context of the East, to stand during Communion is in fact less reverent.
Factually it is not less reverent; culturally you can argue that it is; but cultural issues are subject to change over time. THe Church has the authority to change the posture, as it is a disciplinary matter. You don’t like it, and I have no bone to pick with you about your likes and dislikes. But if the Church says that we stand, then the Church within its authority has the ability to do so and we out of obedience do so, and over time that becomes the culturally accepted posture. However, cultural changes happen over time; 10, 15, 20, 40 or more years may go by before something is accepted as the cultural norm.
Reverence can be had either way; irreverance, or a lack of reverence can also be had either way. Reverence is an attitude, not a feeling.
I recently took our new Catholics from RCIA to our local Byzantine rite Mass (as well as the Maronite Mass). Interestingly this time people seemed to favor the Maronite over the Byzantine rite.
We stood during the Consecration. I felt awkward doing so. However, there certainly did not appear to be any sense of lack of reverence among those who are members of that parish. I could see and participate in the reverence even though the posture was very foreign to me.
Factually, we are required to perform or take the postures which are in the rubrics for our rite. Standing, if that is now the posture for Communion, is in the rubrics; you might not feel comfortable; but confusing your feelings with your attitude puts feelings, or emotion, over attitude - will.
I may have a feeling about someone I don’t like. I can let the feeling adjust my attitude, and the results are never particularly good, or pretty, or usually, Christian. Or I can understand my feelings, but change my attitude. That is an act of the will.
Like my grandmother said, often to my chagrin: “Offer it up”. That puts will over feelings.
