1 Corinthians 3:16 - Ellicott's Commentary On The Whole Bible

The temple of God. — From the thought of grand edifices in general the Apostle goes on to the particular case of a building which is not only splendid but “holy” — the temple of God — thus reminding the reader that the rich and valuable metals and stones spoken of previously are to represent spiritual attainments. He introduces the passage with the words “Do ye not know,” implying that their conduct was such as could only be pursued by those who were either ignorant or forgetful of the truth of which he now reminds them.
