14:34-40 When the apostle exhorts Christian women to seek information on religious subjects from their husbands at home, it shows that believing families ought to assemble for promoting spiritual knowledge. The Spirit of Christ can never contradict itself; and if their revelations are against those of the apostle, they do not come from the same Spirit. The way to keep peace, truth, and order in the church, is to seek that which is good for it, to bear with that which is not hurtful to its welfare, and to keep up good behaviour, order, and decency.
37. prophet—the species.
spiritual—the genus: spiritually endowed. The followers of Apollos prided themselves as "spiritual" (1Co 3:1-3; compare Ga 6:1). Here one capable of discerning spirits is specially meant.
things that I write … commandments of the Lord—a direct assertion of inspiration. Paul's words as an apostle are Christ's words. Paul appeals not merely to one or two, but to a body of men, for the reality of three facts about which no body of men could possibly be mistaken: (1) that his having converted them was not due to mere eloquence, but to the "demonstration of the Spirit and of power"; (2) that part of this demonstration consisted in the communication of miraculous power, which they were then exercising so generally as to require to be corrected in the irregular employment of it; (3) that among these miraculous gifts was one which enabled the "prophet" or "spiritual person" to decide whether Paul's Epistle was Scripture or not. He could not have written so, unless the facts were notoriously true: for he takes them for granted, as consciously known by the whole body of men whom he addresses [Hinds, On Inspiration].
