Fourth Great Awakening
The Fourth Great Awakening was a Christian religious awakening that some scholars — most notably, economic historian Robert Fogel — say took place in the United States in the late 1960s and early 1970s, while others look at the era following World War II. The terminology is controversial, with many historians believing the religious changes that took place in the US during these years were not equivalent to those of the first three great awakenings. Thus, the idea of a Fourth Great Awakening itself has not been generally accepted.
Whether or not they constitute an awakening, many changes did take place. The "mainline" Protestant churches weakened sharply in both membership and influence while the most conservative religious denominations (such as the Southern Baptists and Missouri Synod Lutherans) grew rapidly in numbers, spread across the United States, had grave internal theological battles and schisms, and became politically powerful. Other evangelical and fundamentalist denominations also expanded rapidly. At the same time, secularism grew dramatically, and the more conservative churches saw themselves battling secularism in terms of issues such as gay rights, abortion, and creationism.
New religious movements 
Concomitant to the power shift was a change in evangelicalism itself, with new groups arising and extant ones switching their focus. There was a new emphasis on a personal relationship with Jesus from newly styled 'non-denominational' churches and 'community faith centers'. This period also saw the rise of non-traditional churches and megachurches with conservative theologies and a growth in parachurch organizations while mainline Protestantism lost many members. The Jesus Movement is considered by some to be part of the Fourth Great Awakening.
Synan (1997) argues that a charismatic awakening occurred between 1961 and 1982. This stemmed from a Pentecostal movement that placed emphasis on experiencing what they saw as the gifts of the spirit, including speaking in tongues, healing, and prophecy. It also focused on strengthening spiritual convictions through these gifts and through signs taken to be from the Holy Spirit. Originally a Protestant movement, its influence spread to some in the Roman Catholic Church at a time when Catholic leaders were opening up to more ecumenical beliefs, to a reduced emphasis on institutional structures and an increased emphasis on lay spirituality.
Organized religion has changed in the face of secularizing pressures after World War II. Notable examples include the proliferation of mega-churches, the growth of denominations such as the Assemblies of God, the Latter-day Saints, and the Southern Baptists, and the post-World War II influence of three world-historical religious leaders: Martin Luther King Jr., Billy Graham, and Pope John Paul II. Mega-churches won attention for the simple reason that 10 churches with 2,000 members were more visible than 100 churches with 200 members. The populist denominations' growth coincided with the simultaneous decline of the mainline bodies. While the former trend did not come at the expense of the latter (it represented different fertility and retention rates, not switching), to the media and many ordinary observers those developments signaled the aggressive swelling of religious strength. Finally, it would be hard to find any other period of U.S. history that witnessed three leaders who captured the hearts and minds of millions of Americans as King, Graham, and John Paul did.
The "mainstream" Protestant churches contracted sharply in terms of membership and influence.
After World War Two, some conservative Christian denominations (including the Southern Baptists, Missouri Synod Lutherans, the Church of God, Pentecostals, Holiness groups and Nazarenes) grew rapidly in numbers and also spread nationwide. Some of these denominations, such as the Southern Baptists and Missouri Synod Lutherans), would go on to face theological battles and schisms from the 1960s onward. Many of the more conservative churches would go on to become politically powerful as part of the "religious right." At the same time, the influence of secularism (the belief that government and law should not be based on religion) grew dramatically, and the more conservative churches saw themselves battling secularism in terms of issues such as gay rights, abortion, and creationism.
Byrnes and Segers note regarding the abortion issue, "While more theologically conservative Protestant denominations, such as the Missouri-Synod Lutherans and the Southern Baptist Convention, expressed disapproval of Roe, they became politically active only in the mid and late 1970s." However, the political involvement of churches ranged from actively participating in organizations such as the Moral Majority and the Christian Coalition to adopting the much more indirect and unorganized approach of Missouri Synod Lutherans).
