Changing the Sabbath from Saturday to Sunday without any divine authority is a mortal sin. The Catholic Church fathers admit to committing this sin and perpetuate it throughout generations of followers. Institutionalized sin is still sin and "The wages of sin is death." So says the Almighty God who created Heaven and Earth.While Ratsinger is appollogizng let him appologize for leading the Catholic Church and the Protestants astray with this sin which violates the 10 Commndments and will ultimately destroy the Church. Repent Pope Ratzinger and correct this mortal sin.
