That my friend is hard to believe.
If that was so, how come, Popes, after Popes have visited Muslin nations and communities and wished them well with no malice in their hearts?
Christianity, unlike Islam, is all about love, forgiving, charity and mercy.
The Lord Jesus Christ had opened his sacred heart to all the people he saw, to Romans who were the merciless oppressors, and the Pharisees who were outcasts.
The Pope Gregory the Great had gone out to embrace Muslims of his times with love and was able to spread the flame of Christianity in their hearts, converting a many Muslim to the Christian faith.
Christianity teaches all human to be the children of one Father in His heavenly abode, Who is the King of the Universe and Who feeds and sustains all his children, the entire mankind.
Conversely Muslims were and still are being taught by their clergy and their first preacher Muhammad, and his scriptures the Koran, not to befriend Christians and that all Christians, after the advent of Muhammad, and his revelation of heavenly dialogues, the Koran, who have not shunned their Christan faith and embraced Islam, shall burn eternally in hell!
