The Qur'an teaches Muslims to reject all christians?

The Quran does not teach Muslims to reject all Christians, in fact the Quran in chapter 5 mentioned that the closest to the Muslims in faith are the Christians, because amongst the Christians one will find people who are devoted to learning, who have rejected the world and they are not arrogant.

Unfortunately they are some people who like to pit Muslims against Christians to serve their own agenda...the Quran addresses the Christians with great respect by calling them 'People of the Book'
