When a person becomes a Bahá’í, he gives up the past only in the sense that he is a part of this new and living Faith of God, and must seek to pattern himself, in act and thought, along the lines laid down by Bahá’u’lláh. The fact that he is by origin a Jew or a Christian, a black man or a white man, is not important anymore, but, as you say, lends color and charm to the Bahá’í community in that it demonstrates unity in diversity.
