1 Corinthians 5:4

4. When you are gathered together and my spirit — that is, when ye are gathered together with me, but in spirit, for they could not meet together as to bodily presence. He declares, however, that it would be all one as though he were personally present. It is to be carefully observed, that Paul, though an Apostle, does not himself, as an individual, excommunicate according to his own pleasure, but consults with the Church, that the matter may be transacted by common authority. He, it is true, takes the lead, and shows the way, but, in taking others as his associates, he intimates with sufficient plainness, that this authority does not belong to any one individual. As, however, a multitude never accomplishes anything with moderation or seriousness, if not governed by counsel, there was appointed in the ancient Church a Presbytery, that is, an assembly of elders, who, by the consent of all, had the power of first judging in the case. From them the matter was brought before the people, but it was as a thing already judged of. Whatever the matter may be, it is quite contrary to the appointment of Christ and his Apostles — to the order of the Church, and even to equity itself, that this right should be put into the hands of any one man, of excommunicating at his pleasure any that he may choose. Let us take notice, then, that in excommunicating this limitation be observed — that this part of discipline be exercised by the common counsel of the elders, and with the consent of the people, and that this is a remedy in opposition to tyranny. For nothing is more at variance with the discipline of Christ than tyranny, for which you open a wide door, if you give one man the entire power.

In the name of our Lord For it is not enough that we assemble, if it be not in the name of Christ; for even the wicked assemble together for impious and nefarious conspiracies. Now in order that an assembly may be held in Christ’s name, two things are requisite: first, that we begin by calling upon his name; and secondly, that nothing is attempted but in conformity with his word. Then only do men make an auspicious commencement of anything that they take in hand to do, when they with their heart call upon the Lord that they may be governed by his Spirit, and that their plans may, by his grace, be directed to a happy issue; and farther, when they ask at his mouth, as the Prophet speaks, (Isaiah 30:2,) that is to say, when, after consulting his oracles, they surrender themselves and all their designs to his will in unreserved obedience. If this is becoming even in the least of our actions, how much less ought it to be omitted in important and serious matters, and least of all, when we have to do with God’s business rather than our own? For example, excommunication is an ordinance of God, and not of men; on any occasion, therefore, on which we are to make use of it, where shall we begin if not with God. In short, when Paul exhorts the Corinthians to assemble in the name of Christ, he does not simply require them to make use of Christ’s name, or to confess him with the mouth, (for the wicked themselves can do that,) but to seek him truly and with the heart, and farther, he intimates by this the seriousness and importance of the action.
