While Christianity is Americanâ??s most popular religion (70% of people in the U.S. identify as such), pastors and scholars all let out a collective gasp at the latest findings from the Pew Forum Religious Landscape Study. According to Pew, 2015 might be the year of the religious â??nones,â? as those who do not identify or affiliate with any faith tradition are on the rise, while the number those who call themselves â??Christianâ? is declining. With an eight percentage point drop in just eight years, we are all wondering what American Christianity will look like in two or three generations.
