Final answer:
The explanation of the growth of the Pentecostal Movement in the twentieth century includes a period of religious revivalism, the rise of televangelism, and the influence of earlier evangelical denominations' focus on personal religious experiences and societal reform.
Step-by-step explanation:
The growth of the Pentecostal Movement in the twentieth century is generally regarded as a result of a variety of factors. Its rise was influenced by a period of religious revivalism during the late 1970s and early 1980s in the United States, reminiscent of the Great Awakening, where evangelical sects emphasized personal religious experiences, spiritual rebirth, and the importance of proselytizing. Relationships between the populist ethos of early Pentecostalism and the emphasis on individual spiritual empowerment echoed the earlier revival's democratic spirit.
Additionally, the advent of televangelism allowed charismatic leaders to expand their reach far beyond traditional church walls, bringing Pentecostal theology to millions through television and radio programs like the 700 Club. Televangelists such as Billy Graham and Pat Robertson became national figures, drawing people to the Pentecostal message. Furthermore, the teachings of these movements, which stressed that salvation was available to everyone, appealed to everyday people and marginalized groups, further fueling the growth of the movement.
Another factor in the movement's expansion was the role of evangelical denominations in societal reform during the Second Great Awakening, emphasizing personal vice reforms and a strong community focus that would later influence Pentecostalism. By focusing on spiritual equality, the previously marginalized felt empowered to actively participate in religious communities. Over time, these denominations, including the newer Pentecostal groups, experienced considerable growth due to their direct engagement with the concerns of ordinary people.
