Are there or have there been any Christian traditions that follow Kosher food laws? Kosher food laws are part of Judaism, from which Christianity grew.

But what Christian denominations or traditions follow, or historically have observed Kosher food laws?
The Ethiopian Orthodox Tewahedo Church maintains a practice that resembles Kosher food laws. (There are similarities and differences: the members of this church avoid pork, but they do commonly mix meat and dairy products in their cuisine.)
