Islam & Christianity: Both were born in Blood....
Islam was born in the blood of many at it's inception-for Muhammad wielded the sword on the battlefield of worldly conquest.
Christianity was born in the blood of one man FOR the many-as Christ never wielded the sword from the inception of the Christian faith.
You want to know how a religion is supposed to be followed-don't look at the followers-look at the founders of the religion.
Then said Jesus unto him,
Put up again thy sword into his place:
for all they that take the sword shall perish with the sword.
Matthew 26:52
