This assertion is meaningless. There is more divergency then there will ever be commonality. Moroever, Islam was based on Christian and Jewish notions and yet fundamentally is different. The Jihad is central to Islam for example.It was for 13 centuries or so and still is in many Islamic groups as can plainly be seen. The Jihad has nothing in common with Christian principles nor with principles developed in Judaism down through the centuries.
Moreover, the assertion "Muslims love Jesus as much as Christians" is wholly a patronizing notion. In point of fact, Islam nearly wiped out Eastern Christianity. If Islam loved Christ so much it wouldn't have destroyed whole Christian communities. It wouldn't have dhimmiized and oppressed Christians for centuries. It wouldn't have kidnapped Christian children, and made them Islamic killers as were the Janissaries. It wouldn't have enslaved Christians in Asia Minor, Spain, the Balkans, etc. Islam has never been good for Christianity and it's insulting to suggest any kind of convergence or agreement except in the most oblique ways.
