I’m a Lutheran and I agree with you Brother.
Owl, before you die and go to hell, I would like to point out that the Bible is full of full of stories about Mustard Seeds.
Nothing about Mayonaisse. And that's because mayonaisse is of the devil.
Think about it.
Now, brother, theres nothing inherently evil about mustard per say, but the unholy coupling of mustard and a hamburger is an abomination in Gods eyes.
Jesus, in fact was a huge fan of mustard, especially the spicy brown kind. I site Mark 6-39:
39 And he commanded them to make all sit down and put a sock in it. 40 And they sat down in ranks, by hundreds, and by fifties. 41 And when he had taken the five loaves and the two fishes, he looked up to heaven, and blessed, and brake the loaves into the shape of hot dog buns, and the fish became bun length frankfurters, and they were good. 42 Yea Mark did man the grill and Mathew made haste to fetch mustard and ketchup and relish, the kind thats sweet but not nearly so sweet as India Relish, and onions and kraut and any manner of condiment that grows from the earth, skies and seas. 43 And they took up twelve baskets full of the fragments, and of the frankfurter ends which were thought to be disgusting by the Samaritans, and no one else was really all that hungry anyomre. 44 And He said unto them dress the frank in all My Fathers finery, but do not so bless the burger, for mustard and burgers shall not lie with one another as does it a hot dog, for My Father has said This is gross.
So let us go forth as Christ Commands us, and smite the non-believer and steal his croquet set, and soil his hammock for no good reason, but let us not besmirch the dog with mustard.
