1 Corinthians 11:17-19

Now in this that I am about to declare unto you, I praise you not I cannot commend some, as I have done others, (1 Corinthians 11:2,) for other things; that ye come together Frequently, and even on the most solemn occasions; not for the better So as to gain any spiritual advantage by the increase of your faith and other graces; but for the worse To the prejudice of your souls, by fomenting strifes and animosities, which produce factions. For first of all Before I mention any other instance of your irregular and indecent conduct, I must observe, that when ye come together in the church Εν τη εκκλησια, in the public assembly, though it is evident that nothing but reverence to God, and love to each other, should reign on such occasions; I hear that there be divisions Σχισματα, schisms; among you, and I partly believe it That is, I believe it of some of you. It is plain that by schisms is not meant any separation from the church, but uncharitable divisions in it. For the Corinthians continued to be one church, and notwithstanding all their strife and contention, there was no separation of any one party from the rest, with regard to external communion. And it is in the same sense that the word is used, 1 Corinthians 1:10, and 1 Corinthians 12:25, which are the only places in the New Testament, besides this, where church schisms are mentioned. Therefore, the indulging any temper contrary to this tender care of each other, is the true Scriptural schism. This is, therefore, a quite different thing from that orderly separation from corrupt churches which later ages have stigmatized as schism; and have made a pretence for the vilest cruelties, oppressions, and murders, that have troubled the Christian world. Both heresies and schisms are here mentioned in very near the same sense: unless by schisms be meant rather those inward animosities which occasion heresies; that is, outward divisions or parties: so that while one said, I am of Paul, another, I am of Apollos, this implied both schism and heresy. So wonderfully have later ages distorted the words heresy and schism from their Scriptural meaning. Heresy is not, in all the Bible, taken for “an error in fundamentals,” or in any thing else; nor schism, for any separation made from the outward communion of others. Therefore, both heresy and schism, in the modern sense of the words, are sins that the Scripture knows nothing of; but were invented merely to deprive mankind of the benefit of private judgment, and liberty of conscience. For there must also be heresies among you

Parties formed, as the word αιρεσεις properly signifies. These, in the ordinary course of things, must take place, in consequence of your contentions, and the declension of your love to one another: and God permits these divisions, that they which are approved may be manifest That it may appear who among you are, and who are not, upright of heart.
