Good Men are Like Vowels

My reading today included Spurgeon's Treasury of David on Psalm 33. It included the following quote from "John Kitchin, M.S. in a Funeral Sermon, 1660":

I have sometimes compared the great men of the world, and the good men of the world to the consonants and vowels in the alphabet. The consonants are the most and the biggest letters; they take up most room, and carry the greatest bulk; but, believe it, the vowels though they are the fewest and least of all the letters, yet they are most useful; they give the greatest sound of all; there is no pronunciation without vowels. O beloved, though the great men of the world take up room, and make a show above others, yet they are but consonants, a company of mute and dumb consonants for the most part; the good men they are the vowels that are of the greatest use and most concernment at every turn; a good man to help with his prayers; a good man to advise with his counsels; a good man to interpose with this authority; this is the loss we lament, we have lost a good man; death has blotted out a vowel; and I fear me there will be much silence where he is lacking; silence in the bed, and silence in the house, and silence in the shop, and silence in the church and silence in the parish, for he was everywhere a vowel, a good man in every respect.
