Not only did Constantine enforce SUNday observance in the Roman empire, Pope Alexander III decreed at the Council of Tours in A.D. 1163: "Whereas a damnable heresy (Sabbath-keeping) has for some time lifted its head...and spread infection...concealing itself like a serpent in its folds; as soon as its followers shall have been discovered, let no man afford them refuge on his estates; neither let there be any communications with them in buying and selling..." (Rev. 13:17). People were forbidden to engage in commerce with these "heretics" and "Judaizers." As the hate America/Israel movement grows and spreads across the world, fanned by Satan, blaming British-Israel and Judah for the world's problems and considering us the most serious threat to world peace, expect hatred of anything Jewish/Biblical to increase as well, leading to persecution of all those who choose to follow the Bible rather than traditions. Bomb threats won't only be made against synagogues, but against the Church of God as well (as has happened in the past).
