Why do Christians accept the writings of St Paul as equal to the sayings of Jesus?

In my observations, Protestants tend to focus on Paul rather than Jesus. Paul simply expounded on and taught what Jesus taught. In the Catholic Church, they tend to use Paul as the Second Reading because he was the most prolific writer, but they use it to teach about what Jesus said.

Even though Paul quoted no direct teaching by the Lord Jesus on certain points; he certainly did have God’s spirit, for as noted by the apostle Peter, what Paul wrote was “according to the wisdom given him.” (2 Peter 3:15, 16) Thus, guided by God’s spirit, he was giving his opinion.

When Bible writers expressed such personal convictions, they did so against a background of study and application of the scriptures that were available to them. We can be sure that their writings harmonized with God’s thinking. What they recorded became part of God’s Word.

Paul expounded on Jesus, both his ministry and his words. Paul spoke truth to Christ-followers.

Because "all scripture is inspired of God", 2 Tim. 3:16, and Galatians 1:12 tells us that Paul received the gospel "through the revelation of Jesus Christ."

St. Paul wasnt a prophet, not even one of Jesus's deciples... He was a politician (sounds like Trump).. that wanted voters.. so he "trumped" up a scheme to get followers by changing christianity to suit the wants, needs, and likes of his followers..

Because Paul was taught what he knew by the Holy Spirit and Jesus spoke to him. He also had all the gifts of the Holy Spirit he could speak in tongues heal the sick cast out demons raise the dead all signs that he was indeed an Apostle of Jesus. Thanks for the question.

I don't think of paul's sayings as "equal" to those of Jesus, but, in the same way that I would not reject any sayings/writings of Jesus, I also would not reject any of Paul's writings/sayings.

They are divinely inspired. Holy Spirit is just as much God as Jesus, and Paul was in agreement with God.

Why not?

One fable is as good as another.

probably because he was crucified in a similar fashion ..
