_Direct._ XIV. The catholic church, and particular churches, and our communion with each, must be distinguished; and a man must not be cast out of our catholic communion, because by some tolerable difference he is uncapable of communion with some particular church. If a man be impenitent in any heresy or sin, which is contrary to the common nature of christianity or godliness, and so unfit for catholic communion, he is to be cast out of christian communion: but if some particular church do impose any unnecessary doctrine or practice, and he dare not approve it, or join in it (be it right or wrong); yea, or if he withdraw himself from one church, through the badness of the minister, or through any falling out between them, and join to another that hath a minister more suitable to his case; these are not crimes to be punished with ejection from catholic communion. He that is not fit for communion with some one particular church, may be fit for communion with many others, that give him no such occasion of difference or distaste. Without catholic principles persecution will not be avoided. _Direct._ XV. Let church union and communion be laid upon none but catholic terms, which are possible and fit for all to be agreed in.[130] Common reason will tell any impartial man, that there can be no more effectual engine to divide the churches, and raise contentions and persecutions, than to make laws for church communion, requiring such conditions as it is certain the members cannot consent to. If any man knew that my opinion is against the doctrine of transubstantiation, or of the Dominican's predetermination, and he would make a law, that no man shall have communion with that church who subscribeth not to these, he unavoidably excludeth me (unless I be such a beast, as to believe nothing soundly, and therefore to say any thing). If ever the churches agree, and christians be reconciled, it must be by leaving out all dividing impositions, and requiring nothing as necessary to communion, which all may not rationally be expected to consent in. Now these catholic principles of communion must be such as these. 1. Such points of faith only as constitute christianity, and which every upright christian holdeth; and therefore only such as are contained in our baptismal covenant or profession, which maketh us christians; and not those other which only some stronger christians believe or understand; because the weak are not to be cast out of the family of Christ. 2. Such points as the primitive churches did agree in, and not innovations, which they never practised or agreed in; for they are our pattern, and were better than we; and no more can be necessary to our concord and communion, than was to theirs.[131] 3. Such points as all the church hath some time or other at least agreed in; for what reason can we have to think that the churches should now agree in that, which they never hitherto agreed in.
