Whilst we earnestly inculcate the love of God, we believe that great care is necessary to distinguish it from counterfeits. We think that much which is called piety is worthless. Many have fallen into the error, that there can be no excess in feelings which have God for their object; and, distrusting as coldness that self-possession, without which virtue and devotion lose all their dignity, they have abandoned themselves to extravagances, which have brought contempt on piety. Most certainly, if the love of God be that which often bears its name, the less we have of it the better. If religion be the shipwreck of understanding, we cannot keep too far from it. On this subject, we always speak plainly. We cannot sacrifice our reason to the reputation of zeal. We owe it to truth and religion to maintain, that fanaticism, partial insanity, sudden impressions, and ungovernable transports, are anything rather than piety.
