Our mark
The cross in black, red and white
Christians have joined these two images for centuries. Martin Luther's seal set a black cross inside a red heart, on a white rose. In a letter to Lazarus Spengler on 8 July 1530, Luther explained that the white rose shows how faith brings joy, comfort and peace.
The capsule cross speaks the same language, in the same black, red and white: a cross in one simple shape.
