2 When therefore a man has commenced thus to order his ascent; to speak more plainly, when a Christian has begun to think of spiritual amendment, he begins to suffer the tongues of adversaries. Whoever has not yet suffered from them, has not yet made progress; whoever suffers them not, does not even endeavour to improve. Does he wish to know what we mean? Let him at the same time experience what is reported of us. Let him begin to improve, let him begin to wish to ascend, to wish to despise earthly, fragile, temporal objects, to hold worldly happiness for nothing, to think of God alone, not to rejoice in gain, not to pine at losses, to wish even to sell all his substance, and distribute it among the poor, and to follow Christ; let us see how he suffers the tongues of detractors and of constant opponents, and— a still greater peril— of pretended counsellors, who lead him astray from salvation...He then, who will ascend, first of all prays God against these very tongues: for he says, “When I was in trouble, I called on the Lord; and He heard me”. Why did He hear him? That He might now place him at the steps of ascent.
