Chapter XVIII. How the obstinate and the fickle are to be admonished.
The obstinate are therefore to be admonished, that they acknowledge the haughtiness of their thoughts, and study to vanquish themselves; lest, while they scorn to be overcome by the right advice of others outside themselves, they be held captive within themselves to pride. They are to be admonished to observe wisely how the Son of Man, Whose will is always one with the Father's, that He may afford us an example of subduing our own will, says, I seek not mine own will, but the will of the Father which hath sent me (Joh. v.30). And, still more to commend the grace of this virtue, He declared beforehand that He would retain the same in the last judgment, saying, I can of myself do nothing, but as I hear I judge (Ibid.). With what conscience, then, can a man disdain to acquiesce in the will of another, seeing that the Son of God and of Man, when He comes to shew forth the glory of his power, testifies that of his own self he does not judge?
But, on the other hand, the fickle are to be admonished to strengthen their mind with gravity. For they then dry up the germs of mutability in themselves when they first cut off from their heart the root of levity; since also a strong fabric is built up when a solid place is first provided whereon to lay the foundation. Unless, then, levity of mind be previously guarded against, inconstancy of the thoughts is by no means conquered. From this Paul declared himself to be free, when he said, Did I use levity? or the things that I purpose do I purpose according to the flesh, that with me there should be yea and nay (2 Cor. i.17)? As if to say plainly, For this reason I am moved by no breeze of mutability, that I yield not to the vice of levity.
