The two great dangers which threaten the existence of religions are schism and indifference. In ages of fervent devotion, men sometimes abandon their religion, but they only shake it off in order to adopt another.

Context

“It seems to me that we must first attentively consider what ought to be the natural state of men with regard to religion at the present time; and when we know what we have to hope and to fear, we may discern the end to which our efforts ought to be directed.
The two great dangers which threaten the existence of religions are schism and indifference. In ages of fervent devotion, men sometimes abandon their religion, but they only shake it off in order to adopt another. Their faith changes the objects to which it is directed, but it suffers no decline. The old religion then excites enthusiastic attachment or bitter enmity in either party; some leave it with anger, others cling to it with increased devotedness, and although persuasions differ, irreligion is unknown.” source
