In necessary things unity. To St. Paul this principle meant a clear limit to toleration. There is a common teaching which lies at the basis of the Church which must not be interfered with, which is strictly necessary. 'Though we, or an angel from heaven, should preach unto you any gospel other than that which we preached unto you, let him be anathema[18].' 'How say some among you that there is no resurrection of the dead? But if there is no resurrection of the dead, neither hath Christ been raised: and if Christ hath not been raised, then is our preaching vain, your faith also is vain[19].' Plainly there is an essential fundamental creed which must not be trifled with. The same is true about the moral law. In respect of that also the Christian body must exercise upon its members the severity of judgement[20], that 'he that hath done' the evil deed 'might be taken away from among them,' or excommunicated. Once more, we cannot conceive St. Paul making the necessity of visible unity a secondary consideration[21], nor {148} the recognition of the authority of the apostolic ministry which is to be the centre of unity, nor the sacraments, which again are not only means of divine grace to the individual but instruments and bonds of unity. Nor again would St. Paul undervalue the spirit of obedience to the rules of the Church. He hates the spirit of heresy or separatism. 'We have no such custom,' he would say to the recalcitrant, 'neither the churches of God[22].' Once again, St. Paul is prepared to let everything turn on even a small and unessential point, if that point has become the symbol of a vital principle for good or evil. Thus, in itself, 'circumcision was nothing,' but when among the Galatians the practice of it came to mean a practical Judaizing--a practical abandonment of the fundamental Christian principle--then 'Behold, I Paul say unto you, that, if ye receive circumcision, Christ will profit you nothing[23].' Here, then, are St. Paul's essentials, as to which he is intolerant--a fundamental tradition of faith and morals: the maintenance of the unity of the body by means of the apostolic stewardship, and through the 'one baptism,' and the 'one loaf': and the spirit of due subordination {149} which is necessary to corporate life. But in a spirit very unlike what has at times become prevalent in the Church, he would clearly minimize the action of authority, and leave large room for the free movement of conscience in Christians. 'Let us therefore, as many as be perfect, be thus minded: and if in anything ye are otherwise minded, even this shall God reveal unto you: only, whereunto we have already attained, by that same _rule_ let us walk[24].'
