|Nativity with the Prophets Ezekiel & Isaiah|
The sign itself was always left as free of explanation as possible. More important still is the fact that the Sign did not in the least explain the thing signified. Rather it brought to light essentially and purposefully its very inexplicability, its character of mystery. [Karl Barth Preaching through the Christian Year, p. 108].
