'So called' in the Bible

Even supposing that there are so-called 'gods' either in Heaven or on earth-and there are many such 'gods' and 'lords'-

Do not let any one defraud you of the reality by affecting delight in so-called 'humility' and angel-worship. Such a man busies himself with his visions, and without reason is rendered conceited by his merely human intellect.

Such prohibitions appear reasonable where there is a desire for self-imposed service, and so-called 'humility,' and harsh treatment of the body, but are of no real value against the indulgence of our earthly nature.
