Saint Paul reminds us that we must avoid these sins. He says: ‘Examine yourselves, and only then eat of the bread and drink of the cup’ (1 Cor. 11, 28).
What does it mean that we have first to examine ourselves? What else if not that each of us can come to the Lord’s table only when we’ve first been set to rights and cleansed.
And so that those who are ‘satisfied’ might hear as well, he adds: ‘For all who eat and drink without discerning the body, eat and drink judgement against themselves (1 Cor. 11, 29).
