Selection from Arcana Coelestia ~ Emanuel Swedenborg
When a church is raised up by the Lord, it is in the beginning blameless, and the one then loves the other as his brother, as is known from the case of the primitive church after the Lord's coming. All the church's children then lived together as brethren, and likewise called one another brethren, and loved one another; but in process of time charity grew cold and vanished away and as it vanished, evils succeeded, and together with these falsities insinuated themselves. Hence came schisms and heresies, which would never be the case if charity were regnant and alive, for then they would not even call schism schism, nor heresy heresy, but a doctrinal matter in accordance with each person's opinion; and this they would leave to each person's conscience, provided such doctrinal matter did not deny first principles, that is, the Lord, eternal life, and the Word; and provided it was not contrary to the Divine order, that is, to the precepts of the Decalogue.
(Arcana Coelestia 1834:2)
