And if there be one conviction which, together with the belief in the Incarnation itself of the Word, is common to all the Fathers, Doctors, Saints, and Martyrs of the Church—which together with that belief and as part of it is the ground of their confidence in trouble, of their perseverance in enduring, of their undoubting faith in times of persecution, of their assurance of final victory, it is the sense which encompassed their whole life, that they were members of one Body, which, in virtue of an organic unity in itself and with its Head, was to last for ever. The notion that this Body, as such, could fail, that it could cease to be the treasure-house of the divine truth and grace, would have struck them with as much horror as the notion that Christ had not become incarnate, and was not their Redeemer. The Body which the Holy Ghost animated on the day of Pentecost never ceased to be conscious of its existence—conscious that the power of its Head, the Eternal Truth, was in it, and would be in it for ever. Confidence in himself as an individual member of the Body, the Christian had not, for he knew that through his personal sinfulness grace might be withdrawn from him, and that he might fall away; confidence he did not place either in his own learning, knowledge, and sanctity, or in these gifts as belonging to any individual Christian; his confidence lay in the King who reigned in an everlasting Kingdom, in the Head who animated an incorruptible Body. To sever these two would have been to decapitate Christ.(83) The thought that the Bride of Christ could herself become an adulteress, and teach her children the very falsehoods of that idol-worship which she was created to overthrow, would have appeared to him the denial of all Christian belief. And such a denial indeed it is to any mind which, receiving the Christian truth as a divine gift, looks for it also to have a logical cohesion with itself, to be consistent and complete, to be a body of truth, not a bundle of opinions. Let us take once more S. Augustine as expressing, not a private feeling, but the universal Christian sense, when he thus reprehended the Donatist pretension, that truth had deserted the Body of the Church to dwell in the province of Africa. “But, they say, that Church which was the Church of all nations exists no longer. She has perished. This they say who are not in her. O shameless word! The Church is not because thou art not in her. See, lest therefore thou be not, for though thou be not, she will be. This word, abominable, detestable, full of presumption and falsehood, supported by no truth, illuminated by no wisdom, seasoned with no sense, vain, rash, precipitate, and pernicious—this it was which the Spirit of God foresaw, and as against these very men, when He foretold unity in that saying, ‘To announce the name of the Lord in Zion, and his worship in Jerusalem, when the peoples and kingdoms join together in one that they may serve the Lord.’ ”(84)
