Catholic communion must be “more equal” than Christian communion.
One is real and one is fake.
1 Corinthians 11:27-29 ESV
Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty concerning the body and blood of the Lord. Let a person examine himself, then, and so eat of the bread and drink of the cup. For anyone who eats and drinks without discerning the body eats and drinks judgment on himself.
With respect to the catholic church's rules, I see nothing in scripture that says anything beyond the need for each of us to examine ourselves before taking communion.
