Charles Spurgeon Commentary 1 Corinthians 11:3

"But I would have you know, that the head of every man is Christ; and the head of the woman is the man; and the head of Christ is God." — 1 Corinthians 11:3 (ASV)

Wherefore I give you to understand, that no man speaking by the Spirit of God calleth Jesus accursed:

I suppose that in their assemblies, where everyone who liked to speak did so, there were some people who even spoke blasphemy. They professed to be under the guidance of the Spirit of God, and yet they stood up and called Jesus accursed. Where there is no rule or order, there is very likely to be something mischievous before long. Paul makes them understand that this kind of talk could not go unrebuked.

And that no man can say that Jesus is the Lord, but by the Holy Ghost.

If a man really knows Jesus as his Lord, and he declares that truth, then you may fully accept it as being in harmony with the teaching of the Spirit of God.
