The sum is, Hold fast the substance of religion, and every clear and certain truth, which you see in its own evidence: and also reverence your teachers; especially the universal church, or the generality of wise and godly men; and be not hasty to take up any private opinion; and especially to contradict the opinion of your governors and teachers, in small and controverted things. But yet, in such matters, receive their opinions but with a human faith, till indeed you have more, and therefore, with a supposition, that time and study is very like to alter your apprehensions; and with a reserve, impartially to study and entertain the truth, and not to sit still just where you were born. [Sidenote: What to do when controversies do divide the church.] _Direct._ XII. If controversies occasion any divisions where you live, be sure to look first to the interest of common truth and good, and to the exercise of charity. And become not passionate contenders for any party in the division, or censurers of the peaceable, or of your teachers, that will not overrun their own understandings, to obtain with you the esteem of being orthodox or zealous men; but suspect your own unripe understandings, and silence your opinions till you are clear and certain; and join rather with the moderate and the peacemakers, than with the contenders and dividers. You may easily be sure that division tendeth to the ruin of the church, and the hinderance of the gospel, and the injury of the common interest of religion.[66] You know it is greatly condemned in the Scriptures. You may know that it is usually the exercise and the increase of pride, uncharitableness, and passion; and that the devil is best pleased with it, as being the greatest gainer by it. But, on the other side, you are not easily certain which party is in the right: and if you were, you are not sure that the matter will be worth the cost of the contention: or if it be, it is to be considered, whether the truth is not like to get more advantage by managing it in a more peaceable way, that hath no contention, nor stirreth up other men so much against it, as the way of controversy doth. And whatever it prove, you may and should know, that young christians, that want both parts, and helps, and time, and experience to be thoroughly seen in controversies, are very unfit to make themselves parties; and that they are yet more unfit to be the hottest leaders of these parties, and to spur on their teachers, that know more than they. If the work be fit for another to do, that knoweth on what ground he goeth, and can foresee the end, yet certainly it is not fit for you. And therefore forbear it till you are more fit.
