“As every divided kingdom falls, so every mind divided between many studies confounds and saps itself.”

As quoted in Dictionary of Burning Words of Brilliant Writers (1895) edited by Josiah Hotchkiss Gilbert, p. 285
Context: We worship unity in trinity, and trinity in unity; neither confounding the person nor dividing the substance. There is one person of the Father, another of the Son, and another of the Holy Ghost; but the Godhead of the Father, and of the Son, and of the Holy Ghost, is all one; the glory equal, the majesty co-eternal.

First Epistle to the Corinthians
Context: Now there are diversities of gifts, but the same Spirit.
And there are differences of administrations, but the same Lord.
And there are diversities of operations, but it is the same God which worketh all in all.
But the manifestation of the Spirit is given to every man, to profit withal.
For to one is given, by the Spirit, the word of wisdom; to another the word of knowledge, by the same Spirit;
To another, faith by the same Spirit; to another, the gifts of healing, by the same Spirit;
To another, the working of miracles; to another, prophecy; to another, discerning of spirits; to another, divers kinds of tongues; to another, the interpretation of tongues.
But all these worketh that one and the self-same Spirit, dividing to every man severally, as he will.

§ 2
Reflections on the Formation and Distribution of Wealth (1766)
Context: The earth has been cultivated before it has been divided; the cultivation itself having been the only motive for a division, and for that law which secures to every one his property. For the first persons who have employed themselves in cultivation, have probably worked as much land as their strength would permit, and, consequently, more than was necessary for their own nourishment.

I believe this government cannot endure, permanently half slave and half free. I do not expect the Union to be dissolved — I do not expect the house to fall — but I do expect it will cease to be divided. It will become all one thing or all the other.
In this famous statement, Lincoln is quoting the response of Jesus Christ to those who accused him of being able to cast out devils because he was empowered by the Prince of devils, recorded in Matthew 12:25: "And Jesus knew their thoughts, and said unto them, Every kingdom divided against itself is brought to desolation; and every city or house divided against itself shall not stand".

As quoted in Seeking Peace : Notes and Conversations Along the Way (1998) by Johann Christoph Arnold, p. 155
Context: Just because so many things are in conflict does not mean that we ourselves should be divided. Yet time and time again one hears it said that since we have been put into a conflicting world, we have to adapt to it. Oddly, this completely unchristian idea is most often espoused by so-called Christians, of all people. How can we expect a righteousness to prevail when there is hardly anyone who will give himself up undividedly to a righteous cause?
