Someone once told me that in the rabbincal schools opposing views were accepted as long as they had scriptural basis. I think this toleration would be a good idea for Christians as well. We can reach different conclusions on doctrines depending on how we interpret scripture. The Bible was not written as a definitive text book. Rather, it was written as a guide to live morally and upright. And, interestingly, when the Bible speaks of the final judgment each individual is judged on "deeds" not doctrine.
Christians can disagree on doctrines. But we still should always show respect and kindness toward one another.
