ALL of mainstream Christendom today and for 2,000 years have believed that the Saints are alive in Heaven. A few scattered sects and cults disagree, but many of them also consider Church on Sunday to be pagan, celebrating Easter and Christmas as pagan and some even call venerating the Cross idolatry. They are few but vocal.
ALL of them?
Who knew!!!
Then just WHO are going to come out of their graves at the last trumpet sound?
