Wesley distinguishes between true religion of the heart and the false religion of 'enthusiasm' — meaning, in 18th-century English, a fanatical claim to direct revelation outside Scripture.
Sermon 37 of 44 · 1750 · Acts 26:24
The Nature of Enthusiasm
A passage from the sermon
Enthusiasm in general may then be described in some such manner as this: a religious madness arising from some falsely imagined influence or inspiration of God. It is the imagining one's self to be so influenced by God, as one is not influenced. It is the mistaking the workings of one's own imagination, for the operations of the Spirit of God.
Guard against enthusiasm — but do not, in the dread of it, deny the real work of the Spirit of God. There is a middle path: to seek the Spirit, and to discern between his work and our own. The Spirit of God speaks in conformity to the written Word, never against it; and the surest sign of his presence is the fruit he produces — love, joy, peace, longsuffering, gentleness, goodness, faith.
