We must read the Pauline epistles through the prism of the Gospels, NOT the other way around.
1 Corinthians 2:
9But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.
10 But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.
11For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God.
12 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.
13 Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
And then there is this, where Paul very carefully says where he is giving his own opinion, and not God's commands. My thought is that, as an apostle, if Paul were speaking about God, and did not say it was just an opinion, then it is from God. Otherwise, he would be leading us astray, which isn't what you expect of an apostle.
He wasn't about developing his own philosophy of life, after all, but revealing God's plan. 1 Corinthians 7 1Now concerning the things whereof ye wrote unto me: It is good for a man not to touch a woman.
2Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband.
3Let the husband render unto the wife due benevolence: and likewise also the wife unto the husband.
4The wife hath not power of her own body, but the husband: and likewise also the husband hath not power of his own body, but the wife.
5Defraud ye not one the other, except it be with consent for a time, that ye may give yourselves to fasting and prayer; and come together again, that Satan tempt you not for your incontinency.
6But I speak this by permission, and not of commandment.
7For I would that all men were even as I myself. But every man hath his proper gift of God, one after this manner, and another after that.
8I say therefore to the unmarried and widows, it is good for them if they abide even as I.
No, the letters of Paul are, IMO, just as much God's word as the Gospels.
