1 Corinthians 5:9

(9) I wrote unto you in an epistle not to company with fornicators:

(9) Now he speaks more generally: and that which he spoke before of the incestuous person he shows that it pertains to others, who are known to be wicked and those who through their wicked life are a slander to the Church, who ought also by lawful order be cast out of the community of the Church. And making mention of eating meals, either he means that feast of love at which the supper of the Lord was received, or else their common usage and manner of life. And this is to be properly understood, lest any man should think that either matrimony was broken by excommunication, or such duties hindered and cut off by it, as we owe one to another: children to their parents, subjects to their rulers, servants to their masters, and neighbour to neighbour, to win one another to God.
