I never found Eid in the Qur'an. However, as a community get together, festival, its ok. But I wouldnt call it "ISLAM". Eid often comes with wastage of people's monitory resources, while there are people in the world who can benefit from our money that we waste on Eid. I am not saying that this means that celebrating Eid is HARAM. However, the spirit of RAMADAN gets lost in EID. Where people go back to their usual lifestyle of "PARTYING" and showing off who could spend more and buy more in their Eid shopping.
I dont think I am a Qur'anist. I seek God. God gave a book(Qur'an), I read, I obey.
You are seaking IDEA about following what is in the Qur'an. The best and the only safe option is through reading the Qur'an. None of us here or elsewhere can help you in that case. It is your life, your test. If you can read, why not read ? Read the Qur'an and let the Lord be your shepherd. If you wish to know our views on certain topics, use the search engine in this forum. Do share your views with us too. I would love to learn from you. But , at the end of the day, they are only "our views". The absolute interpretation of the Qur'an belongs to God.
I pray that God guides you to His straight path.
