It is better to wage war with hope of eternal peace than servitude without hope of liberation.
(De Civ. Dei XXI, 15)
Fly over what is bodily and embrace the being of the soul; transcend the soul and please God.
(In Io. Ev. XX, 11)
Because every man is a neighbor to all men, one should not allow any kind of distance where there is a common nature.
(En. in ps. 118, S 8, 2)
