Again, lemme see if I understand you:
So you're saying whether God reaches out and grabs you first (Calvin), or whether you reach out and grab Him first (Arminius), or both, or neither, or something else, is of absolutely no import?
I disagree, because if I were told God loved me and wanted me to be with Him forever, my first question would be: "Ok. How do I do it?" Calvinism, Arminianism, and other doctrines of salvation give us the groundwork for understanding how we are saved.
If we are to be saved by God, one would at least like to know how it's going to work - whether any effort is required of me or not during any point of the process. And if so, what efforts? What will God require of me, and what will He be lenient towards? And such things.
That is why doctrine is so important. It lets you know you are doing God's will, or if you aren't, how to get back on the right track. The most important doctrine, of course, being to do all things in Love. The Greatest Commandments are to Love God and Love our neighbors. Without love, you are a noisy gong and nothing.
The rest of doctrine is just a definition of what Love is and how it is carried out. It's essential because it answers the question "What is love?".
So, then, what is salvation? How does it work? Well, we could argue all day til we are blue in the face. And if I don't stop you at the pass we probably will. We could argue every doctrine, discipline, and thought of humanity until we were long, long dead. But every single doctrine basically comes down to one question:
Why on Earth should I listen to you, or you listen to me, or anyone listen to anyone regarding doctrine, or what they define doctrine as? Prove your authority to teach me and I will follow what you say the Holy Spirit teaches you to the ends of the Earth.
And that brings us back to what I think is the sole problem with Protestantism: authority to teach. Solve that, and then we can get down to answering any other questions you have.
What I am saying is that what they were arguing about didn't matter so much (I suppose some will disagree with me). One does not need to know TULIP to be saved.
That is your opinion, disagreed with by many staunch Calvinists. Prove you have the authority to say they are wrong, and I will believe it.
Again, you have swapped doctrine and Gospel.
Again, who are you to say doctrine is not part of the Gospel?
Prove your authority, if you have any.
I do not claim brothership with those mentioned. I vehemently reject their gospel as another gospel (Galations 1).
Who are you to say they are wrong? On what authority do you say they are wrong?
Anyone can say they speak for Jesus, or they speak for the Holy Spirit.
But proof. Do you have proof you speak for Him?
Let's start with history. I challenge you to show me, historically, what Christianity looked like from the time of the Apostles, through the Dark Ages and the Middle Ages, the Renaissance, to the Enlightenment and the present day. Show me what the Apostles were taught and what they taught, and show me what persisted after they died.
Show me that, Patriot. Show me history.
