Our parish priest recommended receiving the body of Christ in the same way as the Pope offers it to communicants at his Masses. So I started receiving the body of Christ on my knees and on my tongue. At our weekday Mass the blood of Christ is also given. I’m not sure whether I should be on my knees or standing when I receive from the cup. Thanks for any advice.
Unless the pastor makes some sort of special arrangements to enable communicants to receive from the chalice while kneeling (e.g., providing a kneeler), I do not recommend kneeling on your own to receive from the chalice. Without adequate support, such as the armrest of a kneeler, kneeling on your own makes you far more susceptible to spilling the precious blood.
