Well, about 7 of the epistles are considered to be genuinely his, the rest more or less pseudographical. Also you cant really know who Paul even was, since little historical evidence exists for him outside of his own genuine letters, and the somewhat embellished narratives done by the writer of Acts.
I dont discount the teachings of Paul that have universal and logical truths in them, figuratively speaking, but 'God' is certainly NOT limited to just some writings ascribed to Paul, let alone any other religious person or figure. I think one can learn from all, and not just from one religious cult or tradition. Humanity comprises so much more, as one ocean has many rivers.
You are tossed back and forth by the waves.
Ephesians 4:14 Then we will no longer be infants, tossed back and forth by the waves, and blown here and there by every wind of teaching and by the cunning and craftiness of people in their deceitful scheming.
Read what Luke says.
He says he himself have carefully investigated everything from the beginning and wrote an orderly account of everything. He was with Jesus from the beginning.
Luke 1:1-4 Many have undertaken to draw up an account of the things that have been fulfilled among us, just as they were handed down to us by those who from the first were eyewitnesses and servants of the word. Therefore, since I myself have carefully investigated everything from the beginning, it seemed good also to me to write an orderly account for you, most excellent Theophilus, so that you may know the certainty of the things you have been taught.
Read what John says.
He says there are things not recorded in the book he wrote, but what is written is so that one may believe.
John 20:30 Jesus performed many other signs in the presence of his disciples, which are not recorded in this book. 31 But these are written that you may believe that Jesus is the Messiah, the Son of God, and that by believing you may have life in his name.
Read what Peter says.
He says that Old Testament writings were revealed to as what they meant.
As 2 Peter 1:20-21 says. Above all, you must understand that no prophecy of Scripture came about by the prophet’s own interpretation. For prophecy never had its origin in the will of man, but men spoke from God as they were carried along by the Holy Spirit.
Paul explains the same thing.
Romans 16:25-27 Now to him who is able to establish you by my gospel and the proclamation of Jesus Christ, according to the revelation of the mystery hidden for long ages past, but now revealed and made known through the prophetic writings by the command of the eternal God, so that all nations might believe and obey him–to the only wise God be glory forever through Jesus Christ! Amen.
2 Timothy 3:14 But as for you, continue in what you have learned and have become convinced of, because you know those from whom you learned, and how from infancy you have known the holy Scriptures, which are able to make you wise for salvation through faith in Christ Jesus. All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the man of God may be thoroughly equipped for every good work.
Scripture is the ultimate authority. Psalms 138:2 …for you have exalted above all things your name and your word.
We are warned not to do what you do.
You go to other sources about God.
You pick and choose what you want to believe and throw out the rest.
You have a different God and Jesus.
You are as the thief who didn't go through the gate.
Isaiah 8:20 To the law and to the testimony! If they do not speak according to the word, they have no light of dawn.
You just do not speak according to the word all the time.
The apostles from the New Testament received all the truth we need to guide us to eternal life. All we need to guide us to eternal life is written down in the Scriptures: John 16:13; 2 Peter 1:3; Acts 20:20, 27; Matthew 28:20; I Corinthians 14:37; 2 Timothy 3:16, 17.
God the Almighty knew exactly what would be in the Holy Bible. He is the Almighty and knows how to preserve His Word.
