A study by Ellison Research says more Americans consider adultery (81 percent) and racism (74 percent) sin, than homosexual activity (52 percent--the same as cheating on your taxes) or getting drunk (41 percent.)
According to the survey:
Protestants are more likely than Roman Catholics to include most of the thirty different behaviors as sin – sometimes dramatically so. The biggest differences include gambling (50% of Protestant churchgoers define this as sinful, compared to just 15% of Catholics), failing to tithe 10% or more of one’s income (32% to 9%), getting drunk (63% to 28%), gossip (70% to 45%), and homosexual activity or sex (72% to 49%). Catholics and Protestants are equally likely (or unlikely) to list as sin having an abortion, spanking, and making a lot of money, while Catholics are more likely than Protestants to believe that failing to attend church is a sin (39% to 23%).
Evangelical Christians are far more likely than almost any other group to include numerous behaviors under the definition of sin, and the difference between evangelicals and other Americans is often quite large.
Have a look.
