I dont think so. God tells me in in Chapter 2 vere 62
[2:62] Those who believe (in the Qur'an), and those who follow the Jewish (scriptures), and the Christians and the Sabians,- any who believe in Allah and the Last Day, and work righteousness, shall have their reward with their Lord; on them shall be no fear, nor shall they grieveSo anyone who performs the righteous deeds, believes in one God, believes that he/she will be responsible for his/her acts on the day of judgement - be that person Christian, Jew, Hindu or anyone else - can enter paradise.
I like what this verse says. So I think so.
