“Now, since on God's own testimony, men are 'flesh', they can savour of nothing but the flesh; therefore 'free-will can avail only to sin. And if, while the Spirit of God is calling and teaching among them, they go from bad to worse, what could they do when left to themselves, without the Spirit of God? Your [Erasmus] observation that Moses is speaking of the men of that age is not to the point at all. The same is true of all men, for all are 'flesh'; as Christ says, 'That which is born of the flesh is flesh' (John 3:6) How grave a defect this is, He Himself there teaches, when he says: 'Except a man be born again, he cannot enter the kingdom of God (v. 5)…I call a man ungodly if he is without the Spirit of God; for Scripture says that the Spirit is given to justify the ungodly. As Christ distinguished the Spirit from the flesh, saying: "that which is born of the flesh is flesh', and adds that which is born of the flesh cannot enter the kingdom of God', it obviously follows that whatever is flesh is ungodly, under God's wrath, and a stranger to His kingdom. And if it is a stranger to God's kingdom and Spirit, it follows of necessity that it is under the kingdom and spirit of Satan. For there is no middle kingdom between the kingdom of God and the Kingdom of Satan, which are ever at war with each other.”

Valence of Prince Berthold, in Act IV.
Colombe's Birthday (1844)
Context: p>He gathers earth's whole good into his arms;
Standing, as man now, stately, strong and wise,
Marching to fortune, not surprised by her.
One great aim, like a guiding-star, above—
Which tasks strength, wisdom, stateliness, to lift
His manhood to the height that takes the prize;
A prize not near — lest overlooking earth
He rashly spring to seize it — nor remote,
So that he rest upon his path content:
But day by day, while shimmering grows shine,
And the faint circlet prophesies the orb,
He sees so much as, just evolving these,
The stateliness, the wisdom and the strength,
To due completion, will suffice this life,
And lead him at his grandest to the grave.
After this star, out of a night he springs;
A beggar's cradle for the throne of thrones
He quits; so, mounting, feels each step he mounts,
Nor, as from each to each exultingly
He passes, overleaps one grade of joy.
This, for his own good: — with the world, each gift
Of God and man, — reality, tradition,
Fancy and fact — so well environ him,
That as a mystic panoply they serve —
Of force, untenanted, to awe mankind,
And work his purpose out with half the world,
While he, their master, dexterously slipt
From such encumbrance, is meantime employed
With his own prowess on the other half.
Thus shall he prosper, every day's success
Adding, to what is he, a solid strength —
An aery might to what encircles him,
Till at the last, so life's routine lends help,
That as the Emperor only breathes and moves,
His shadow shall be watched, his step or stalk
Become a comfort or a portent, how
He trails his ermine take significance, —
Till even his power shall cease to be most power,
And men shall dread his weakness more, nor dare
Peril their earth its bravest, first and best,
Its typified invincibility.Thus shall he go on, greatening, till he ends—
The man of men, the spirit of all flesh,
The fiery centre of an earthly world!</p

I found this nowhere there.

XII. The origin of evil things; and that there is no positive evil.
On the Gods and the Cosmos

Ich spreche von jener Religion, in deren ersten Dogmen eine Verdammnis alles Fleisches enthalten ist, und die dem Geiste nicht bloß eine Obermacht über das Fleisch zugesteht, sondern auch dieses abtöten will, um den Geist zu verherrlichen; ich spreche von jener Religion, durch deren unnatürliche Aufgabe ganz eigentlich die Sünde und die Hypokrisie in die Welt gekommen, indem eben durch die Verdammnis des Fleisches die unschuldigsten Sinnenfreuden eine Sünde geworden und durch die Unmöglichkeit, ganz Geist zu sein, die Hypokrisie sich ausbilden mußte.
