Now when we desire to cast off the old man, by our own labour and weariness we perceive that we are casting him off, not by the hearing of faith only, but also by the experience of works, and by the sufferings, and tears, and the love of God, and by pure prayers, and by constant entreaties, and by admiration of the greatness of the glory of God, and by constant admiration of Him, and by the urgent hastening of the inner man may be with God; with these and such like things, while we labour earnestly, we put on the new man, not by the hearing of the ear, but by the perception of our soul, and by the true experience of the knowledge of the Spirit. Therefore in this country a man beginneth to grow in the knowledge which is above the world, where there is room for the stature to grow, and where he may attain unto the limit of the height of growth. For so long as abominable passions envelop a man like an after-birth, and fetter the limbs of the new man, his growth is impeded, and the man is not able to arrive at that measure of stature which is given by Christ, and concerning which Paul said, “We all grow and become one thing in the knowledge of the Son of God, and one perfect man, in the measure of the stature of the fulness of Christ.” Now unless a man hath gone forth from the world he is not able to arrive at this measure, and unless he hath first cast off all the conversation of the body he is not able to arrive at the knowledge by which he will perceive the greatness of these things which are given in a mystery by Christ.

And the forms under which we cast off [the old man], and put on [the new man] are these: — in baptism we cast off the old man, and put on the new man; and [we cast off] bondage, and put on freedom; and [we cast off] corporeality, and put on spirituality; and [we cast off] sin, and put on righteousness; and so forth, but [we do them] all by the hearing of faith. And although they may all be with us in very truth at the birth by baptism, yet are they all strangers to our perception; but when we come to the measure of the stature of the body which is able to distinguish virtues from vices, by the good will and earnestness of our soul we begin to cast off vices and to put on virtues, and [to cast off] iniquity, and to put on righteousness, and [to cast off] oppression, and to become givers, and [to cast off] cruelty, and to become loving, and [to cast off] hardness, and to become gracious, and [to cast off] rapacity, and to become merciful. And all these things, and many others like unto them arise from the will which feareth God; and which fighteth against the world, that little by little the man may grow through these things, until he casteth away the whole world entirely, and maketh himself destitute of everything that is therein, and standeth without impediment in his own person, and appeareth in the other world of the conversation of Christ like the natural child who casteth off the womb, and cometh into being outside thereof. — Second Discourse on Poverty.
