“At thy right hand there are pleasures for evermore” (Ps. 16: 11)
The Basket Case Chronicles #170
“If therefore the whole church be come together into one place, and all speak with tongues, and there come in those that are unlearned, or unbelievers, will they not say that ye are mad? But if all prophesy, and there come in one that believeth not, or one unlearned, he is convinced of all, he is judged of all: And thus are the secrets of his heart made manifest; and so falling down on his face he will worship God, and report that God is in you of a truth” (1 Cor. 14:23–25).
Paul has just finished telling us that to have a bunch of people chattering in a language that you don’t understand is represented by Isaiah as a sign of judgment. He then moves on into application. If an unbeliever or an untutored person comes into your assembly, you should want the service to be edifying to them. But if everybody is speaking in tongues, the ungifted or unbelieving will simply dismiss you as being crazy. But this dismissal would indicate that they are under judgment—as we see with the people who dismissed the Christians on Pentecost as being drunk. But Paul does say that for the believers to pray in tongues in church together is a provocation—and that is not our calling.
On the other hand, if the words spoken in the service of words of intelligible prophecy, then unbeliever comes under the judgment of his own conscience, which is the way we avoid coming under the judgment of God. The secrets of his heart are laid bare by intelligible speech, and causes him to confess that God is indeed present.
This is why an assembly of Christians all speaking together in an unintelligible way is simply a way of telling non-Christians to go to Hell. And while a worship service is not structured in order to cater to non-believers, it should anticipate their presence, and not place needless obstacles in front of them.
