A student of the modern methods of the higher criticism asked ‘Abdu’l-Bahá if he would do well to continue in the church with which he had been associated all his life, and whose language was full of meaning to him. ‘Abdu’l-Bahá answered: “You must not dissociate yourself from it. Know this; 98 the Kingdom of God is not in any Society; some seekers go through many Societies as a traveller goes through many cities till he reach his destination. If you belong to a Society already do not forsake your brothers.
You can be a Bahá’í-Christian, a Bahá’í-Freemason, a Bahá’í-Jew, a Bahá’í-Muḥammadán. The number nine contains eight, and seven, and all the other numbers, and does not deny any of them. Do not distress or deny anyone by saying ‘He is not a Bahá’í!’ He will be known by his deeds. There are no secrets among Bahá’ís; a Bahá’í does not hide anything.”
