“All the reasons which made the initiation of physical force evil, make the retaliatory use of physical force a moral imperative.”

“Can the use of physical force ever be reconciled with the family spirit?”
Source: Jesus or Christianity: A Study in Contrasts (1929), p. 21
Context: Can the use of physical force ever be reconciled with the family spirit?... On one occasion he appears to have resorted to force himself... It sheds no light upon the question as to whether the taking of life, capital punishment, or war are ever justifiable. The criterion by which Jesus judges every method is this; Can it be used appropriately in the home?

1770s, Letter to Lindley Murray (1774)
Context: Among the strange things of this world, nothing seems more strange than that men pursuing happiness should knowingly quit the right and take a wrong road, and frequently do what their judgments neither approve nor prefer. Yet so is the fact; and this fact points strongly to the necessity of our being healed, or restored, or regenerated by a power more energetic than any of those which properly belong to the human mind.
We perceive that a great breach has been made in the moral and physical systems by the introduction of moral and physical evil; how or why, we know not; so, however, it is, and it certainly seems proper that this breach should be closed and order restored. For this purpose only one adequate plan has ever appeared in the world, and that is the Christian dispensation. In this plan I have full faith. Man, in his present state, appears to be a degraded creature; his best gold is mixed with dross, and his best motives are very far from being pure and free from earth and impurity.

The Critic as Artist (1891), Part II
Context: England has done one thing; it has invented and established Public Opinion, which is an attempt to organize the ignorance of the community, and to elevate it to the dignity of physical force.

“We must meet hate with love. We must meet physical force with soul force.”
1950s, Give Us the Ballot (1957)
Context: We must meet hate with love. We must meet physical force with soul force. There is still a voice crying out through the vista of time, saying: "Love your enemies, bless them that curse you, pray for them that despitefully use you." Then, and only then, can you matriculate into the university of eternal life. That same voice cries out in terms lifted to cosmic proportions: "He who lives by the sword will perish by the sword." And history is replete with the bleached bones of nations that failed to follow this command. We must follow nonviolence and love.
