When a Church is raised up by the Lord, it is in the beginning
blameless; and one then loves the other as his brother, as we know of
the primitive Church after the Lord's advent. At that time, all the
sons of the Church lived together like brothers, and also called one
another brother, and mutually loved each other. But in the course of
time charity diminished, and vanished; and as it vanished, evils
succeeded; and together with evils falsities insinuated themselves.
Hence came schisms and heresies, which would never come to be, were
charity regnant and alive.
