Abstract: The Christianity worshipped by Taiping Tianguo (Heavenly Kingdom of Peace) Movement had been considered heresy by Western missionaries. In the recent years，Chinese scholars have also dismissed this brand of Christianity as cult. In fact，the religious ideal-minor heaven，preached by Taiping Tianguo’s“heaven on earth”was no different from that of the“white sun world”，worshipped by the secret societies in Ming and Qing dynasties. Therefore，the Taiping Tianguo’s brand of Christianity should be considered as“secret Western religion”. The practice of such a religious ideal shows，the religious leader and his senior followers have indeed realized the extravagant lives comparable to that of the“heaven on earth”. However，the rank and file of the rebellion still endure the cruelty and suppression of the senior leaders.
