Actually, it is rather a paradox - some branches of Lutheranism maintained Catholic practice (and even, to some extent, liturgical theology) until fairly recently.
Especially, the Church of Sweden. I read the liturgical changes in the Swedish Lutheran Church were externally more conservative than the Novus Ordo back in the 16th cent.
I believe the priests simply told the laypeople it was the Mass they were used to translated in to Swedish.
I saw a picture of my great-grandfather's Church of Sweden parish in Pitea, Sweden and it was more Catholic than the Novus Ordo churches.
