I just stumbled upon a great webpage with a very eclectic canon of "saints". These range from the pious (e.g. Jesus Christ, Teresa of Avila, Malcom X) to the less so (e.g. John Coltrane, William Shakespeare).
Perhaps the most random saint illustrated is Jesus historian Norman Perrin.
No Barth, no Bultmann, no C.H. Dodd, no Morna Hooker... but Perrin gets the halo.
