1. AND so say all the world, the men who know not God, of all that are of _Paul_’s religion; of every one who is so a follower of him, as he was of Christ. It is true, there is a sort of religion, nay and it is called Christianity too, which may be practised without any such imputation, which is generally allowed to be consistent with common sense. That is, a religion of form, a round of outward duties, performed in a decent, regular manner. You may add orthodoxy thereto, a system of right opinions, yea, and some quantity of Heathen morality. And yet not many will pronounce, that _much_ religion _hath made you mad_. But if you aim at the religion of the heart, if you talk of righteousness and peace and joy in the Holy Ghost, then it will not be long before _your_ sentence is past, _Thou art beside thyself_. 2. And it is no compliment which the men of the world pay you herein. They, for once, mean what they say. They not only affirm, but cordially believe, that every man is _beside himself_, who says, the love of God is shed abroad in his heart, by the Holy Ghost given unto him, and that God has enabled him to rejoice in Christ, with joy unspeakable and full of glory. If a man is indeed alive to God, and dead to all things here below; if he continually sees him that is invisible, and accordingly walks by faith and not by sight: then they account it a clear case: beyond all dispute, _much_ religion _hath made him mad_. 3. *It is easy to observe, that the determinate thing which the world accounts madness, is that utter contempt of all temporal things, and steady pursuit of things eternal; that divine conviction of things not seen; that rejoicing in the favour of God; that happy, holy love of God; and that testimony of his Spirit with our spirit, that we are the children of God. That is, in truth, the whole spirit and life and power of the religion of Jesus Christ. 4. They will however allow, in other respects, the man acts and talks like one in his senses. In other things, he is a reasonable man: ’tis in these instances only his head is touched. It is therefore acknowledged, that the madness under which he labours, is of a particular kind. And accordingly they are accustomed to distinguish it by a particular name, _Enthusiasm_. 5. A term this, which is exceeding frequently used, which is scarce ever out of some men’s mouths. And yet it is exceeding rarely understood, even by those who use it most. It may be therefore not unacceptable to serious men, to all who desire to understand what they speak or hear, if I endeavour to explain the meaning of this term, to shew what _Enthusiasm_ is. It may be an encouragement to those who are unjustly charged therewith: and may possibly be of use, to some who are justly charged with it, at least to others, who might be so, were they not cautioned against it.
