Matthew Poole and continuators on 1 Corinthians 14:40

40 Let all things be done decently, and in order .

He forbad them not to speak with Tongues, provided they did it decently and orderly, as all other things ought to be done in so grave an Assembly, as that of the Church, and in so grave an Action, as the Worship of God. For Women to prophesie in the publick Assemblies, was an undecent thing, v. 35. he had said, that it was a shame. For many of them to speak together, confusedly, making a noise, that was disorderly; nor did this decency or indecency, order or disorder, arise from obeying or disobeying the Apostolical Constitution, but from the Law of God, the Light of Nature, the common usage of all the Churches of Christians, as v. 33. All things ought so be done, (especially in Religious Assemblies and Actions) as they may not be judged by the Law of God, or the Light of Nature, or the common custom of other Churches, to be done indecently or confusedly, without order. It is very observable, That though the Apostle, in these things, hath given Rules, yet he hath determined nothing shameful or uncomely, but what he hath made to appear so, either from the Divine Law, (as in the case of the womens prophesying, v. 34.) or from Nature and Reason, (as in the case of many speaking at the same time) it being useless to the end, which was teaching and instructing those to whom they spake, and what Unbelievers would count the effect of madness, v. 23.
