Jerusalem, Antioch, Ephesus, Corinth, Rome--what a various scene of activity these centres of Christian life presented! The Churches founded in these great cities must have differed in many features. Even in the communities of his own province the apostle did not, so far as we can judge, impose a uniform administration. St Peter and St Paul carried out their plans independently, only maintaining a general understanding with each other. The apostolic founders, inspired by one and the self-same Spirit, could labour at a distance, upon material and by methods extremely various, with entire confidence in each other and with an assurance of the unity of result which their teaching and administration would exhibit. The many buildings rested on the one foundation of the apostles. “Whether it were I or they,” says our apostle, “so we preach, and so you believed.” Where there is the same Spirit and the same Lord, men do not need to be scrupulous about visible conformity. Elasticity and individual initiative admit of entire harmony of principle. The hand may do its work without irritating and obstructing the eye; and the foot run on its errands without mistrusting the ear. Such was the catholicism of the apostolic age. The true reading of verse 21, as it is restored by the Revisers, is an incidental witness to the date of the epistle. A churchman of the second century, writing under Paul’s name in the interests of catholic unity as it was then understood, would scarcely have penned such a sentence without attaching to the subject the definite article: he must have written “all the building,” as the copyists from whom the received text proceeds very naturally have done. From that time onwards, as the system of the ecclesiastical hierarchy was developed, external unity was more and more strictly imposed. The original “diversity of operations” became a rigid uniformity. The Church swallowed up the Churches. Finally, the spiritual bureaucracy of Rome gathered all ecclesiastical power into one centre, and placed the direction of Western Christendom in the hands of a single priest, whom it declared to be the Vicar of Jesus Christ and endowed with the Divine attribute of infallibility. Had not Jerusalem been overthrown and its Church destroyed, the hierarchical movement would probably have made that city, rather than Rome, its centre. This was in fact the tendency, if not the express purpose of the Judaistic party in the Church. St Paul had vindicated in his earlier epistles the freedom of the Gentile Christian communities, and their right of non-conformity to Jewish usage. In the words “each several building, fitly framed together,” there is an echo of this controversy. The Churches of his mission claim a standing side by side with those founded by other apostles. For himself and his Gentile brethren he seems to say, in the presence of the primitive Church and its leaders: “As they are Christ’s, so also are we.”
