 The Bahá 'í Faith ( Persian : بهائیت Bahá 'iyyat , Arabic : بهائية Bahá 'iyya / bəˈhaɪ / ) is a monotheistic religion which emphasizes the spiritual unity of all humankind . Three core principles establish a basis for Bahá 'í teachings and doctrine : the unity of God , that there is only one God who is the source of all creation ; the unity of religion , that all major religions have the same spiritual source and come from the same God ; and the unity of humanity , that all humans have been created equal , coupled with the unity in diversity , that diversity of race and culture are seen as worthy of appreciation and acceptance . According to the Bahá 'í Faith 's teachings , the human purpose is to learn to know and to love God through such methods as prayer , reflection and being of service to humanity .
