A man that is an heretic
An heretic, according to the notation of the word, is either one that makes choice of an opinion upon his own judgment, contrary to the generally received sense of the churches of Christ, and prefers it to theirs, and obstinately persists in it; separates from them, forms a party, and sets himself at the head of them, whom he has drawn into the same way of thinking with himself: or he is one that removes and takes away a fundamental doctrine of Christianity, which affects particularly the doctrine of the Trinity, the deity, and personality of Father, Son, and Spirit, and especially the doctrines relating to the person, office, and grace of Christ; one that brings in, or receives damnable doctrines; speaks or professes perverse things, and draws away disciples after him; or is among such disciples: for though schism and heresy do differ, and every schismatic may not be an heretic, yet every heretic is a schismatic; he makes a rent in the doctrine of Christ, and makes parties and divisions in his church; and such are not always to be contended and disputed with, but to be avoided and rejected:
after the first and second admonition reject;
have nothing to do with him; have no society with him; admit him not to private conversation; and eject him from church communion, after he has been publicly admonished twice by the order of the church; for this is not to be understood of private admonition, by a particular person or persons; as in the case of private offences, ( Matthew 18:15 Matthew 18:16 ) but of public admonition, in the name of the church. An admonition with the Jews did not continue less than seven days F1; some say F2 thirty; that is, there were so many days before it was out, or between one and another.
