Yep, and here's what the Word of God says, which is exactly what the Church says:
1 Corinthians 11:27
27 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.
“Unworthy manner” There is not direct definition here to accompany this particular wording. That is interpreted by man as he and she reads and deciphers scripture. Once again it goes back to what you are commenting on.
Again, worthiness is between a man and his God, not between a man and his church.
“Who is he that judges another man’s servant? to his own master he stands or falls. Yes, he shall be held up: for God is able to make him stand” Rom 14:4.
