Actually, many of Paul's epistles were only applicable to a specific church being addressed to....
No, they contain some advice for specific churches according to their situation, and in some - e.g Corinthians - Paul answers specific questions that they asked, that may not have been relevant to the church in Philippi, for example.
But his words about dying with Christ through baptism, life in the Spirirt and nothing separating us from the love of God, were not just for the church at Rome. His teaching about Christ being raised from the dead, and our resurrection bodies was not just for the church at Corinth. His words about being saved by Grace were not just for the church at Ephesus - and so on.
What this means is NOT all of Paul's teachings apply to us. We're not supposed to be teaching them all in churches! They were very specific for a time period and for a specific culture. Certainly not ours!
"While we were still sinners, Christ died for us" Romans 5:8
"Nothing can separate us from the love of God" Romans 8:39
"The Lord Jesus, on the night he was betrayed, took bread, and when he had given thanks, he broke it and said 'this is my body' ...." 1 Corinthians 11:23-25
"Love is patient, love is kind ......" 1 Corinthians 13:4-8
"God made him who had no sin, to be sin for us, so that in him we might become the righteousness of God" 2 Corinthians 5:21
"it is by grace you have been saved" Ephesians 2:5
""our attitude should be the same as Christ Jesus, who, being in very nature God, did not consider equality with God something to be grasped but made himself nothing ............... Philippians 2:5-11
These are only for a certain time and culture??
As Apostle Peter have said, many have misunderstood Paul's letters in their time......
No he didn't. He said that Paul's letters "contain SOME things which are hard to understand, which
ignorant and unstable people distort" 2 Peter 3:16
And we are still doing it TODAY!
That's because some people don't study Paul's letters to find out what he was saying, who he was addressing, what his words mean in context etc, they just take a verse, out of context, and claim that it applies to everyone today, equally, no question.
If people don't study the Scriptures to find out what the authors meant by what they wrote, and what the people receiving/hearing their words would have understood; if they don't ask themselves what kind of literature it is, look at the context and so on, then they can make the Scriptures say anything they want them to say - so they are distorting them.
Many Christian denominations that don't agree with each other,
I think you'll find that all Christian denominations agree on the Gospel, the Trinity, the virgin birth, in fact those things contained in the Nicene creed. Those that don't; JWs, Mormons etc - are not denominations but cults.
The things we disagree on are, imo, largely to do with church practice - eg type of baptism, wearing robes, ordaining women - and have nothing to do with salvation.
