It is not to be imagined that the unity of the body of Christ is interfered with when a community based upon unsound principles, or countenancing unsound doctrine or practice, is separated from. The Church of Rome charged the Reformers with schism because they separated from her; but we know that the Church of Rome lay, and still lies, under the charge of schism because she imposes false doctrine upon her members. Let it only be ascertained that the truth of God is called in question by any community, and that, to be a member of that community, I must identify myself with unsound doctrine or corrupt practice, and then it cannot be schism to separate from such a community; nay, I am bound to separate.
[XIV.] It is usual to apply the term "unworthily," in this passage, to _persons_ doing the act, whereas it really refers to the _manner_ of doing it. The apostle never thought of calling in question the Christianity of the Corinthians; nay, in the opening address of his epistle, he looks at them as "the Church of God which is at Corinth, sanctified in Christ Jesus, called saints" (or saints by calling). How could he use this language in the first chapter, and in the eleventh call in question the worthiness of these saints to take their seat at the Lord's Supper? Impossible. He looked upon them as saints, and as such he exhorted them to celebrate the Lord's Supper in a worthy manner. The question of any but true Christians being there, is never raised; so that it is utterly impossible that the word "unworthily" could apply to _persons_. Its application is entirely to the _manner_. The persons were worthy, but their manner was not; and they were called, as saints, to judge themselves as to their _ways_, else the Lord might judge them in their _persons_ as was already the case. In a word, it was as true Christians they were called to judge themselves. If they were in doubt as to that, they were utterly unable to judge anything. I never think of setting my child to judge as to whether he is my child or not; but I expect him to judge himself as to his habits, else, if he do not, I may have to do, by chastening, what he ought to do by self-judgment. It is because I look upon him as my child, that I will not allow him to sit at my table with soiled garments and disorderly manners.
