What is our free will, which stands in between the lust of the flesh and the spirit.
Between these two desires then the free will of the soul stands in an intermediate position somewhat worthy of blame, and neither delights in the excesses of sin, nor acquiesces in the sorrows of virtue. Seeking to restrain itself from carnal passions in such a way as not nevertheless to be willing to undergo the requisite suffering, and wanting to secure bodily chastity without chastising the flesh, and to acquire purity of heart without the exertion of vigils, and to abound in spiritual virtues together with carnal ease, and to attain the grace of patience without the irritation of contradiction, and to practise the humility of Christ without the loss of worldly honour, to aim at the simplicity of religion in conjunction with worldly ambition, to serve Christ not without the praise and favour of men, to profess the strictness which truth demands without giving the slightest offence to anybody: in a word, it is anxious to pursue future blessings in such a way as not to lose present ones. And this free will would never lead us to attain true perfection, but would plunge us into a most miserable condition of lukewarmness, and make us like those who are rebuked by the Lords remonstrance in the Apocalypse: “I know thy works, that thou art neither hot nor cold. I would that thou wert hot or cold. But now thou art lukewarm, and I will forthwith spue thee out of my mouth;” 1303 were it not that these contentions which rise up on both sides disturb and destroy this condition of lukewarmness. For when we give in to this free will of ours and want to let ourselves go in the direction of this slackness, at once the desires of the flesh start up, and injure us with their sinful passions, and do not suffer us to continue in that state of purity in which we delight, and allure us to that cold and thorny path of pleasure which we have to dread. Again, if inflamed with fervour of spirit, we want to root out the works of the flesh, and without any regard to human weakness try to raise ourselves altogether to excessive efforts after virtue, the frailty of the flesh comes in, and recalls us and restrains us from that over excess of spirit which is bad for us: and so the result is that as these two desires are contradicting each other in a struggle of this kind, the souls free will, which does not like either to give itself up entirely to carnal desires, nor to throw itself into the exertions which virtue calls for, is tempered as it were by a fair balance, while this struggle between the two hinders that more dangerous free will of the soul, and makes a sort of equitable balance in the scales of our body, which marks out the limits of flesh and spirit most accurately, and does not allow the mind inflamed with fervour of spirit to sway to the right hand, nor the flesh to incline through the pricks of sin, to the left. And while this struggle goes on day after day in us to our profit, we are driven most beneficially to come to that fourth stage which we do not like, so as to gain purity of heart not by ease and carelessness, but by constant efforts and p. 335 contrition of spirit; to retain our chastity of the flesh by prolonged fastings, hunger, thirst, and watchfulness; to acquire purpose of heart by reading, vigils, constant prayer and the wretchedness of solitude; to preserve patience by the endurance of tribulation; to serve our Maker in the midst of blasphemies and abounding insults; to follow after truth if need be amid the hatred of the world and its enmity; and while, with such a struggle going on in our body, we are secured from slothful carelessness, and incited to that effort which is against the grain, and to the desire for virtue, our proper balance is admirably secured, and on one side the languid choice of our free will is tempered by fervour of spirit, and on the other the frigid coldness of the flesh is moderated by a gentle warmth, and while the desire of the spirit does not allow the mind to be dragged into unbridled licence, neither does the weakness of the flesh allow the spirit to be drawn on to unreasonable aspirations after holiness, lest in the one case incentives to all kinds of sins might arise, or in the other the earliest of all sins might lift its head and wound us with a yet more fatal dart of pride: but a due equilibrium will result from this struggle, and open to us a safe and secure path of virtue between the two, and teach the soldier of Christ ever to walk on the Kings highway. And thus the result will be that when, in consequence of the lukewarmness arising from this sluggish will of which we have spoken, the mind has been more easily entangled in carnal desires, it is checked by the desire of the spirit, which by no means acquiesces in earthly sins; and again, if through over much feeling our spirit has been carried in unbounded fervour and towards ill-considered and impossible heights, it is recalled by the weakness of the flesh to sounder considerations and rising above the lukewarm condition of our free will with due proportion and even course proceeds along the way of perfection. Something of this sort we hear that the Lord ordained in the case of the building of that tower in the book of Genesis, where a confusion of tongues suddenly sprang up, and put a stop to the blasphemous and wicked attempts of men. For there would have remained there in opposition to God, aye and against the interest of those who had begun to assail His Divine Majesty, an agreement boding no good, unless by Gods providence the difference of languages, raising disturbances among them, had forced them because of the variations of their words to go on to a better condition, and a happy and valuable discord had recalled to salvation those whom a ruinous union had driven to destruction, as when divisions arose they began to experience human weakness of which when puffed up by their wicked plots they had hitherto known nothing.
