Without controversy, the mystery of godliness is great: God was revealed in the flesh, Justified in the spirit, Seen by angels, Preached among the nations, Believed on in the world, And received up in glory.
In the flesh - In human nature; see this explained in the notes on Romans 1:3. The expression here looks as though the true reading of the much-disputed word was “God.” It could not have been, it would seem evident, ὁ ho, “which,” referring to “mystery;” for how could a mystery “be manifested in the flesh?” Nor could it it be ὅς hos, “who,” unless that should refer to one who was more than a man; for how absurd would it be to say that “a man was manifested, or appeared in the flesh!” How else could a man appear? The phrase here means that God appeared in human form, or with human nature; and this is declared to be the “great” truth so long concealed from human view, but now revealed as constituting the fundamental doctrine of the gospel. The expressions which follow in this verse refer to God “as” thus manifested in the flesh; to the Saviour as he appeared on earth, regarded as a divine and human being. It was the fact that he thus appeared and sustained this character, which made the things which are immediately specified so remarkable, and so worthy of attention.
