'Fact' in the Bible

It is said, in fact, that there is among you a sin of the flesh, such as is not seen even among the Gentiles, that one of you has his father's wife.

If to others I am not an Apostle, at least I am one to you: for the fact that you are Christians is the sign that I am an Apostle.

Right and wrong, I say, not for you, but for the other man; for the fact that I am free is not dependent on another man's sense of right or wrong.

But it is important for you to keep this fact in mind, that the head of every man is Christ; and the head of the woman is the man, and the head of Christ is God.
