Now, brothers, for your benefit I have applied all this only to Apollos and myself, by using us as illustrations to teach you the old lesson, "Never go beyond the letter," and to keep any of you from boasting of one teacher at the expense of another.

but one Christian has to go to law with another, and before unbelievers too?

If one of the heathen invites you to his house, and you wish to go, eat whatever is served, without raising any question, as far as conscience is concerned.

And if it seems worth while for me to go myself, they can go with me.
