“If you want to see the holy Christian Church painted in glowing colors and in a form which is really alive, and if you want this to be done in a miniature, you must get hold of the Psalter, and there you will have in your possession a fine, clear, pure mirror which will show you what Christianity really is; yea, you will find yourself in it and the true ‘know thyself’, and God himself and all his creatures, too” (Martin Luther, Preface to the German Psalter [1528]).
