Especially given St. Paul's admonition:
"Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of profaning the body and blood of the Lord. Let a man examine himself, and so eat of the bread and drink of the cup"
(1 Cor. 11:2728).
This is an absolute requirement which can never be dispensed. To receive the Eucharist without sanctifying grace in your soul profanes the Eucharist in the most grievous manner.
