The great Fr. Nicola Bux has excellent comments about the reception of Holy Communion. They are posted (back on 20 July) on the Italian language site Pontifex.Roma.
He makes the observation that reception of Holy Communion standing is not necessarily bad. It can be reverent, especially when received with a proper understanding, signs of reverence, head coverings for women, etc. But often it seems as if people are queuing for buffet.
Furthermore, people often go to Communion rather mechanically, without a sense of what they are about or what Communion is.
Reception of Holy Communion kneeling could be a real help for a return to greater understanding and devotion.
