'So called' in the Bible

But now I am writing to you to stop associating with any so-called brother if he is sexually immoral, greedy, an idolater, a slanderer, a drunk, or a robber. You must even stop eating with someone like that.

For even if there are "gods" in heaven and on earth (as indeed there are many so-called "gods" and "lords"),

He opposes and exalts himself above every so-called god and object of worship. As a result, he seats himself in the sanctuary of God and himself declares that he is God.
