Has Christianity Caused Wars?

A Christadelphian Video: Description: The Bible teaches that Christians treat people with respect, mercy and justice. The teaching of Jesus in the scriptures has been changed to suit the needs of politicians and emperors. Over the centuries, personal convictions have become more important than Bible teaching. Differences & division over practices rather than doctrine were set aside as the introduction of doctrines by the emperors have remained unchanged by retaining the ideas of Greek & Egyptian Mythology. True Christians do not fight.
