[Ali Imran]

Yes..besides the differences in scholars opinions...sunni and Shias also have different interpretations of certain Quranic verses and passages...

Only minute, like 0.001% of Shias have a different theology. Other than that, we have almost a 100% agreement on theology. We all say God is One, with no partners. We all say the Quran is the verbatim word of Allah, and preserved. We all say Muhammad صلي الله عليه وسلم is the messenger of Allah. We all believe in the 5 pillars of Islam and the 6 articles of faith. We all do solah the same way, fast on Ramadan, and perform Hajj together.

Now, tell me again if the differences in the scholarly interpretations cause a division in theology.
