Most US Christians don't believe Satan, Holy Spirit really exist
- "Nearly six out of ten Christians surveyed either strongly agreed or somewhat agreed with the statement that Satan "is not a living being but is a symbol of evil""
- "In contrast, about 35 per cent of American Christians believe Satan is real."
- "Interestingly, the majority of Christians believe a person can be under the influence of spiritual forces, such as demons or evil spirits, even though many of these same people believe Satan is merely a symbol of evil. Two out of three Christians agreed that such forces are real (39 per cent agreed strongly, 25 per cent agreed somewhat)."
Off topic but I found this interesting:
"More than one-fifth (22 percent) strongly agreed that Jesus Christ sinned when He lived on earth, with an additional 17 percent agreeing somewhat."
