[1.] First, He endeavours to gain the heart by the ingenuous, sweet, and delightful society of those that are corrupted already. Error hath a peculiar art to woo the good-will before it disclose itself. It first steals the ear and affections to the person, and thence insensibly derives it to the opinion. Truth is masculine, and persuades by teaching, but error doth often teach by persuading. It is very difficult to affect the person, and not to bestow upon the error better thoughts than it deserves. Those therefore that are cunning in the art of seduction, make extraordinary pretences of affectionate kindness, and, as the apostle noted concerning the seducers of his time, Gal. iv. 17, ‘they zealously affect’ those whom they would delude, ‘but not well.’ Their art doth also teach them not to be over-hasty in propounding their opinions, nor so much as to touch upon them, till they perceive they have gained a firm persuasion of their amity, and of the reality of those kindnesses which they have made show of; but when they have once gained this point of advantage, they take opportunity more freely to propound and press their doctrines. Thus are men at last beguiled ‘with enticing words.’

It is also part of the same design that Satan sometimes makes use of women seducers: For, (1.) They are more apt to be deluded themselves: ‘silly women’ are soon ‘led captive.’ (2.) Being deceived, they are most earnestly forward in the heat of zeal to propagate their opinions. (3.) And by the advantage of their nature they are most engaging; their affectionate persuasions usually have a peculiar prevalency. The daughters of Moab, through Balaam’s counsel, were made choice of as the fittest instruments to seduce Israel to idolatry. Solomon, though a wise man, was prevailed with by the importunity of his wives, against his former practice and knowledge, to favour false worship. The woman Jezebel, Rev. ii. 20, was Satan’s under-agent ‘to teach and seduce God’s servants to commit fornication, and to eat things sacrificed to idols.’ (4.) Besides, they have a greater influence upon their children to leaven them with their own opinions.

[2.] Secondly, Satan also observes a gradual motion in fixing any particular error. If he attempt it immediately, without an external agent, he first puts men upon the reading or consideration of some dark passages that seem to look favourably upon his design; then he starts the notion or objection; then begets a scruple or questioning. Having once proceeded thus far, he follows his design with probable reasons, till he have formed it into an opinion. When it is come to this, a little more begets a persuasion, that persuasion he ripens into a resoluteness and obstinacy, and then at last fires it with zeal for the deluding of others. Having thus laid the foundation by one error, he next endeavours to multiply it, and then brings in the inferences that unavoidably follow; for as one wedge makes way for another, so from one falsehood another will easily force itself, and from two or three who knows how many? And though the consequences are usually more absurd than the principles, yet are they with a small labour brought into favour where the principles are first confidently believed; so that those errors, which because of their ugly look Satan durst not at first propound, lest he should scare men off from their reception, he can now with an undaunted boldness recommend. It cannot be imagined that ever men would at first have entertained opinions of contempt of ordinances and libertinism, and therefore we may observe they usually come in the rear of other opinions, which by a long tract of art prepare their way.

Yet may we note, that though Satan usually is forced to wait the leisure of some men’s timorousness and bashfulness, and therefore cannot ripen error to a hasty birth as he desires, hence is it that one man often doth no more for his time, but only brew it, or, it may be, makes only the rude draught of it, and another vents and adorns it; for so it was betwixt Lælius and Faustus Socinus, betwixt David George and his successors. And though he be so confined to the first principles of error which he hath instilled that he cannot at present enlarge them beyond their own just consequences; yet there are some choice principles of his which, if he can but fasten upon the mind, they presently open the gap to all kind of errors imaginable. They are like the firing a train of gunpowder, which in a moment blows up the whole fabric of truth. Such are the delusions of enthusiasm, inspirations, and prophetic raptures. Let these be once fixed, and then there is nothing so inhuman, irreligious, mad, or ridiculous, but Satan can with ease persuade men to it, and also under the highest pretences of religion and certainty. The experience of all ages hath made any further proof of this altogether needless.

This is his way when he acts alone. But if he use instruments, though he is also gradual in his procedure, yet it is in a different method; for there he sometimes proceeds from the abuse of something innocent and lawful, by the help of a long tract of time, to introduce the grossest falsehood. Thus may we conceive he brought idolatry to its height: first men admired the wisdom or famous acts of their progenitors or benefactors; next they erected pillars or images of such persons to perpetuate the names, honour, and memory of them and their actions. Another age, being at a greater distance from the things done, and consequently greater strangers to the true ends and reasons of such practices, which being, as it usually falls out in such cases, abused by false reports or misrepresentations of things—for time covers things of this nature with so thick a mist that it is difficult to discover the true metal of an original constitution—they in a devout ignorance gave the images a greater respect than was at first intended. Then did they slide into a conceit they were not of the ordinary rank of mortals, or at least they were exalted to a condition which ordinary mortals were not capable of. Thus they supposed them deities, and gave them worship of prayers and sacrifices. Hence they went further, and multiplied gods, and that of several sorts, according to the natures of things that were good or hurtful to them; and then at last consulting how mean their offerings were, and how unlikely to please their godships, they concluded human sacrifices most suitable, especially to expiate greater provocations, and in times of great calamity.

The burdensome heap of ceremonious superstitions in popery was the work of several ages; they were not brought in all at once. One in a devotional heat fancied such a ceremony as a fit testimony of zeal, or a proper incitement of his affections; another deviseth a second, and so all along. As the minds of men were best pleased with their own inventions, and had so much credit or authority to recommend them to others, they increased the sum by new additions, till at last they are become a burden not to be borne; and still as they receded from the primitive purity, and became more careless and corrupt in their lives—for from good bishops they declined to but tolerable archbishops, till at last they are become incurable Babylonians—so they departed gradually from the simplicity of the gospel, and abounded in contrivances of ceremonies.[289]

[3.] Thirdly, In corrupting established truths. Satan’s proceedings are not by sudden and observable leaps, but by lingering and slow motions—as flowers and plants grow insensibly, and as men gradually wax old and feeble. Violent and hasty alterations he knows would beget observation, dislike, and opposition; neither will he make such attempts but where he is sure of a strong prevalent party, which by force and power is able to carry all before it. In this case he is willing to enforce error by fire and sword. Thus he propagated Mohammedanism at first, and still continueth to do so by the conquering arms of the Turks; but where he hath not this advantage, he betakes himself to another course, and studieth to do his work so that he may not be observed. The possibility of such a change, with the manner of effecting it, we may observe in many churches that have declined from the doctrine which they at first received, but most of all in the church at Rome, which at first was a pure church, as the apostle testifieth, but now so changed from the truths upon which they were bottomed in their first constitution, as if she had not been the same church. They boast indeed that as they were at first, so they are now; but nothing is more evident than the contrary; and the possibility of their insensible corruption is as demonstrable as the alteration of doctrine in any other church. The manifold ways that Satan takes in this matter, in the abuse of Scripture, by raising perverse interpretations and unnatural inferences, and the advantages of a long succession in authority; of the negligence and ignorance of the common people; of the crafty subtlety of the teachers, especially when religion began to be abused to secular interest, is described by Acontius and others.[290] If we should single out any of their noted errors, and follow up the history of it to its first original, we shall find that whatever strong current it hath now gotten, it was very small and inconsiderable in the fountain. The invocation of saints, though it be now an established article among them, yet its first rise was from the unwary prosopopœias of the ancients, and the liberty of their oratorical declamatory style. These gave occasion to some private opinions, these opinions to some private devotional liberty in practice, and from private opinions and practices, at last it obtained so strong a party that it procured a public injunction. The like method was used for the doctrine of transubstantiation, whose beginning was from the abuse of such sentences as this in ancient writers, that ‘after consecration it was no more bread and wine, but the body and blood of Christ;’ by which expression the authors intended no more than this, that the bread and wine in the sacrament were relatively altered, and were more than ordinary bread and wine, because they were representatives of the body and blood of Christ: however, this gave them courage to interpret literally and strictly these words of Christ, ‘This is my body;’ and thus by degrees from the opinion of a few it became the judgment of many, and from the toleration of a private opinion of some doctors, and unimposed, it obtained at last a canon to make it authentic public doctrine.

[4.] Fourthly, This insensible proceeding is in nothing more evident than in the power of custom and education. Custom doth by degrees take off the startling of conscience; and those opinions or practices which at first look affright it, are by a little familiarity made more smooth and tolerable. The dissents of men by frequent seeing and hearing become tame and gentle; but the force of education is incomparably great, for this makes an error to become as it were natural; they suck it in with their milk, and draw it in with their air. This general advantage the devil hath over all the children of erroneous parents, especially where countries or nations are of the same persuasion; insomuch that Turks have as great belief of their Alcoran as we of the Bible, and think as reverently of Mohammed as Christians do of Christ. The children of idolatrous pagans have as great a confidence of the truth of their way of heathenish worship, as we have of God’s ordinances and institutions.

[5.] Fifthly, We may see something of this stratagem of silent entanglement in Satan’s surprisals; for sometimes he inveigles men at unawares, and engageth them in error while they know not what they are doing. Weak heads cannot see the far end of a smooth-faced doctrine, and they usually embrace it by wholesale, for some particular that strikes upon their fancy, or gratifies their humour. If they read a book that hath some good things in it, or is affectionate, for the sake of these they swallow all the rest, though never so dangerous doctrine, without further examination. The like advantage he hath from actions that are bad or tolerable, according to the various respects which they have to the ends or consequences that lie before them; for he frequently doth interest men in an erroneous consequence, by concerning them in actions that lead that way; and having thus beguiled them into an evil mistake, instead of drawing their foot out of the snare, he pusheth them forward to maintain their ground, and to justify their proceedings. This was the case of some of the Corinthians; when the heathens had offered a sacrifice to an idol, part of the sacrifice was reserved, and either sold at the shambles, or used in a feast, to which the heathens sometimes invited their Christian acquaintance or relations. Those that went, knowing that ‘an idol was nothing,’ ate what was set before them without any regard to the idol, and ‘making no question for conscience sake;’ by their example others that ‘had not that knowledge,’ 1 Cor. viii. 7, were emboldened, not only to eat against their scruples and doubts of conscience,—which is all that many interpreters think to be intended in that place,—but also—as the words make probable—with some positive regard to the idol; so that by the examples of those that sat in the idol’s temple, eating what was set before them as common meat, others misinterpreting their actions, proceeded to eat with a conscience of the idol, as if the idol had been something indeed, and deserving a conscientious regard. Not unlike to this was that art of Julian, mentioned by Sozomen, whereby he endeavoured to twist something of paganism with actions and things that were lawful or necessary.[291] He caused the images of Mars and Mercury to be placed by his own, so that the respects that were payed to the emperor’s picture, seemed to carry a concomitancy of reverence to those idols. He also, in prosecution of the same policy, caused their meats and drinks to be sprinkled or mixed with the lustral water, that so every one that used them might be inured to give some regard to his idols; and that some, at least, might be engaged to a justification of that and such other practices.

All these are but instances of Satan’s silent insinuation, by which he secretly steals the affections, and through these taints the judgment. Next follows,
