Wherefore, lest we fall into the same error, and be laughed to scorn, arguing thus with Greeks whenever we have a controversy with them; let us charge the Apostles with want of learning for the same charge is praise. And when they say that the Apostles were rude, let us follow up the remark and say that they were also untaught, and unlettered, and poor, and vile, and stupid, and obscure. It is not a slander on the Apostles to say so, but it is even a glory that, being such, they should have outshone the whole world.

How do we learn to trust in God rather than our abilities? What kind of opinion should we have of ourselves?
