OTOH your leaders in the Catholic church have promulgated these: Papal_Bulls_Jews.
Seems to be a discrepancy. Lots of doctrinal claims re: Luther, but zero substance. Catholics: Special badges or dress for Jews. Special taxes for Jews, Forcing Jews to remit debt of Christians, Banning, confiscating or burning Jewish law books and other writings, Encouraging or forcing conversion of Jews, Expelling Jews from Papal territories or forcing Jews to live in ghettos, Inquisition for backsliding converted Jews. No doubt more of that 'were part of the ordinary day-to-day teaching of the Church' that we heard about so recently.
How does the Confessional Lutheran church differ from the Lutheran church ? I assume it follows the Protestant model. The church was founded by a man of the times (Luther, Calvin, Zwingli, etc.) and not by our LORD Jesus Christ. It caught on for a while until its adherents either tired of the man and/or his doctrine. They refined, reformed, split, or latched onto another man. A new religion/sect/denominational name was selected to differentiate them from whatever group they were now protesting against, and so it goes to this day.
Since the Lutheran Church was founded by Martin Luther, it cannot disown him. His life is defined by everything he wrote down for posterity. It reflects the spirit within him.
Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves. Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles? Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit. A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. Wherefore by their fruits ye shall know them. Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
