The Apostolic Faith Mission (Los Angeles) is always considered as the symbolic origin of the Pentecostal Movement which started at the beginning of the Twentieth Century. The Apostolic Faith Mission's worship style deeply influenced other Pentecostal communities at that time and later in the movement. But the researches about the particular worship style of the Apostolic Faith Mission are not enough. In this paper, I will analyze the worship from two periods: the first one is in the revival period (1906-1913), and the other one is after the revival (after 1913). Hope we can understand the Pentecostal Movement better through this research.
