A Sincere Reflection on the Oneness of God Across Abrahamic Faiths

Assalamu alaykum, everyone. I just wanted to share some thoughts that have been on my mind lately, not to start any arguments, but because I’m truly curious and hope some of you will keep an open mind too. Lately, I’ve been learning a bit about Judaism, Christianity, and Islam, and I can’t ignore how much they have in common. All three believe in one God, honor Prophet Ibrahim (peace be upon him), share many prophets, and emphasize prayer, humility, charity, justice, and repentance. So it got me thinking: could these traditions be different ways that people have understood their relationship with the same God? I know major differences exist, especially when it comes to Prophet Isa (Jesus, peace be upon him), and that’s where my mind keeps circling. For example, the Trinity in Christianity-I’ve been trying to wrap my head around it. I understand Christians don’t believe in three gods, but one God shown through the Father, Son, and Holy Spirit. So what if the Trinity isn’t about separate beings, but rather one God revealing Himself in different ways? Like the Father is the source, the Son is how God’s message came to humanity through Isa (peace be upon him), and the Holy Spirit is God’s presence at work in the world. Now, I know in Islam we strictly believe God is One, and Isa (peace be upon him) is a blessed messenger and the Messiah, not God incarnate. But then we come to the crucifixion-a big point of difference. Christians believe Isa (peace be upon him) died on the cross and was resurrected. The Qur’an says, “They did not kill him, nor did they crucify him…” (4:157) and that Allah raised him up. Could these views somehow not be total contradictions? Maybe the Qur’an is stressing that God Himself cannot be defeated or killed, while Christianity focuses on the human experience of suffering and rising. Perhaps the human aspect of Isa (peace be upon him) underwent death, but the divine reality of Allah was untouched? I know that’s not a mainstream Islamic or Christian take, but I wonder if some scholars have explored such ideas. Another thing that’s been on my mind is salvation. If Allah is perfectly just and knows every person’s heart, their struggles, and what chances they had, could salvation be about more than just a label? Like, what if someone genuinely seeks God, does good, and lives with love and humility-could they be judged with mercy even if they didn’t know the full truth? As a Muslim, I trust Allah’s justice and mercy, but I’m curious how others see this. I’d love to hear from my Muslim brothers and sisters, as well as any Christians or Jews who might come across this. Some questions I have: 1. Has anything like this been discussed in Islamic, Christian, or Jewish scholarship? 2. What are the strongest reasons to reject this idea from an Islamic perspective? 3. Where does this kind of interpretation clearly conflict with the Qur’an, Bible, or Torah (I mean within each scripture itself, not just between the faiths)? 4. Are there ways to see these religions as connected rather than completely separate paths? Again, I’m not trying to prove anything or have a debate. I really just want to learn from your insights and perspectives. Jazakum Allahu khayran for reading, and may Allah guide us all to the truth.
