Charisma magazine has reported the findings of the Barna Research Group (BRG) on the witnessing habits of Christians in various denominations. George Barna discovered that only one out of three adults in Protestant churches witnessed to a nonbeliever last year. He discovered that Pentecostal, Assemblies of God, and Mormons were the most active in religious endeavors. When it came to Bible reading, Pentecostals at 75% were the most active. The least active Bible readers were Catholics, Episcopalians, and Lutherans. Mormons were more likely to read the Bible weekly than Protestants overall.
