Early Christianity and Its Decline
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.
