"You ask again, am I exercising the ministry on my own nomination? I trust not, for if I am, the work will come to nought; I trust I exercise it on the nomination of my Lord by His Spirit; if you can point to any other nomination as necessary, or that there are any persons excluded until they are appointed by man, I hope I am willing to weigh the evidence you bring.
"I wish you, however, distinctly to understand, I do not object to ordination by men, if it be exercised on principles consistent with Scripture, but if they think they confer anything more than their permission to preaching in their little part of the fold of Christ, I should decline it until they shew how they came by that authority from the word of God, and what are the scriptural rules and limitations of this authority."
---from a letter by Anthony Norris Groves to a friend, in 1828
1) Disorderly ministering is not of the Spirit and is liable to correction by the elders.
2) False teaching is not of the Spirit and is subject to the discernment of the saints and to correction by any or all, subject in turn to elder oversight.
"Planned meetings" preempt the sovereign Spirit from leading the meetings through the various members of the body. In planned meetings, men decide who ministers, and when. But this "order" is not of God. There is indeed no difference between a "low church" planned meeting and a liturgy, as it is called. Both preempt the Spirit's leading.
We are taught that believers can, each of us, grieve the Spirit; it follows that the Spirit may be grieved by our corporate actions as well, and not only the actions we sponsor but also those we condone.
