The problem with "only" following Paul's teaching is many twist his writings to make them in conflict with Jesus and we are warned in doing this, can be a salvation issue.
2 Peter 3:15 and consider
that the longsuffering of our Lord
is salvation—as also our beloved brother Paul, according to the wisdom given to him, has written to you, 16 as also in all his epistles, speaking in them of these things, i
n which are some things hard to understand,
which untaught and unstable people twist to their own destruction,
as they do also the rest of the Scriptures.
The other reason is Paul followed Christ
1 Cor 11:1 Imitate me, just as
I also imitate Christ.
So a lot of people who use Paul's writings against what Jesus taught and lived, also use Paul's writings against Paul as many never reconcile his writings to his other writings or more importantly to Jesus.
Paul was commissioned to teach the gospel but he is not a replacement for what Jesus taught and lived. The covenant ratified at His Cross, nothing can be added or changed to His covenant. No one is going to be saved by Paul, we are only saved by the blood of Jesus through faith in Him and of Him- which is how did Jesus live and what He taught, as He is our example to follow 1 Peter 2:21-22 Heb 4:15 1 John 2:6
Jesus is the way, Paul, just like other good apostles and prophets point to Jesus. Anytime, we take away Jesus in any capacity, its not the path that leads us to eternal life.
John 14:6
Jesus said to him, “
I am the way, the truth, and the life.
No one comes to the Father
except through Me.
Rev 14:12 Here is the [
a]patience of the saints; here[
b]
are those who
keep the commandments of God and the faith
of Jesus.
