11 But, as every one praises most what is within his reach, let us pass now to the cottage-inn which sheltered Christ and Mary. With what expressions and what language can we set before you the cave of the Saviour? The stall where he cried as a babe can be best honored by silence; for words are inadequate to speak its praise. Where are the spacious porticoes? Where are the gilded ceilings? Where are the mansions furnished by the miserable toil of doomed wretches? Where are the costly halls raised by untitled opulence for man's vile body to walk in? Where are the roofs that intercept the sky, as if anything could be finer than the expanse of heaven? Behold, in this poor crevice of the earth the Creator of the heavens was born; here He was wrapped in swaddling clothes; here He was seen by the shepherds; here He was pointed out by the star; here He was adored by the wise men. This spot is holier, me-thinks, than that Tarpeian rock which has shown itself displeasing to God by the frequency with which it has been struck by lightning.
