Santorum has adopted the Muslim view on separation of church and state?

Separation Of Church And State

Dr. Jaafar Sheikh Idris

Separation of church and state is widely accepted in the West and thus has become a globally political thought. Historically, the idea emerged as a practical strategy for dealing with issues related to the Christians and other people in the Western culture.

Gradually, however, separation of church and state has become a popular premise for all modern states. It is now seen that citizenship rather than religion should be the basis for belonging to a state, since different citizens may have different religions. If the state commits to one religion, members of other faiths would feel alienated since a foreign religion would be imposed upon them. They may be prohibited from practicing the rituals of their religion and they may be deprived of their right to hold certain positions in the state, such as president, or other key positions. This would create disturbances and conflicts that would present obstacles for the progress of the state.

...

So how are Muslims to approach the modern trend of separation of religion and state in their countries? The basic belief in Islam is that the Qur'an is one hundred percent the word of God, and the Sunna was also as a result of the guidance of God to the Prophet peace be upon him. Islam cannot be separated from the state because it guides Muslims through every detail of running the state and their lives. Muslims have no choice but to reject secularism for it excludes the laws of God.
