_Direct._ XVII. Let not an inordinate respect to man, or common custom, be too strong a bias to pervert your judgments from the rule of worship; nor yet any groundless prejudice make you distaste that which is not to be disliked. The error on these two extremes doth fill the world with corruption and contentions about the worship of God. Among the papists, and Russians, and other ignorant sorts of christians, abundance of corruptions are continued in God's worship by the mere power of custom, tradition, and education; and all seemeth right to which they have been long used: and hence the churches in south, east, and west continue so long overspread with ignorance, and refuse reformation.[34] And on the other side, mere prejudice makes some so much distaste a prescribed form of prayer, or the way of worship which they have not been used to, and which they have heard some good men speak against, whose judgments they highliest esteemed, that they have not room for sober, impartial reason to deliberate, try, and judge. Factions have engaged most christians in the world into several parties, whereby Satan hath got this great advantage, that instead of worshipping God in love and concord, they lay out their zeal in an envious, bitter, censorious, uncharitable reproaching the manner of each other's worship. And because the interest of their parties requireth this, they think the interest of the church and cause of God requireth it; and that they do God service when they make the religion of other men seem odious: whenas among most christians in the world, the errors of their modes of worship are not so great as the adverse parties represent them (except only the two great crimes of the popish worship: 1. That it is not understood, and so is soulless. 2. They worship bread as God himself, which I am not so able as willing to excuse from being idolatry). Judge not in such cases by passion, partiality, and prejudice.[35] _Direct._ XVIII. Yet judge in all such controversies with that reverence and charity which is due to the universal and the primitive church. If you find any thing in God's worship which the primitive or universal church agreed in, you may be sure that it is nothing but what is consistent with acceptable worship; for God never rejected the worship of the primitive or universal church. And it is not so much as to be judged erroneous without great deliberation and very good proof. We must be much more suspicious of our own understandings.
