Baha'i is an offshoot of Islam like Christianity is an offshoot of the Jewish religion. The difference between Baha'i and Christianity is that they are accepting of all people, faith or no faith, most churches will only tolerate you if you convert. If it becomes apparent that you have no intention to convert, you become just another black sheep. Some will shun you. They are only friendly if they think they can make you theirs. The Baha'i do not evangelize, try to convert or judge. They know the truth is universal and not contained in just one religion. That is what makes them so friendly. They place no conditions on friendship. Christians, for the most part, do.
Christians accept people my friend. It's when people hear the message that they're sinners and need God's forgiveness that they get all uppity and self-righteous because they would rather trust in their own "goodness" (which they don't have) rather than their creator. "Don't judge me". When people accuse Christians of not tolerating the sinner, what they're actually saying is "why won't you tolerate my sin?".
Sinner(person) vs sin(acts). There's a difference.
In the original texts, Jesus supposedly said he was a child of god and that we are all children of god.
Prove it.
