Luke 12:7

When our Lord said, "not a hair," he was not thinking of length but of the number of hairs, as we see from these words, "The hairs of your head are numbered." I still think that nothing that was a natural part of the body should be lost. Ugly outgrowths, which have the purpose of reminding us of the penal condition of mortal life, will be integrated into the substance as a whole so that no deformity will appear in any one part. After all, a human artist can make a botch of a statue and then reshape it into beauty without a loss of any of his material. It is not a matter of chiseling away some paticular part that was ugly or out of proportion. He can break down and remold the same mass of material so that nothing but the blemish disappears. Of course, the omnipotent Artist can do this even better. There is no deformity of any human body, whether normal, exceptional or even monstrous, which he cannot so eliminate as to leave the total substance intact, while the ugliness disappears. Such outgrowths are not out of place among the other miseries of temporal existence, but they are incompatible with the happiness of the saints in the life to come.

It is His care then diligently to know the life of the saints. Whence it follows, But the hairs of your heads are all numbered; by which He means, that of all things which relate to them He has most accurate knowledge, for the numbering manifests the minuteness of the care exercised. Now mystically, indeed, the head of a man is his understanding, but his hairs the thoughts, which are open to the eye of God.

We must not read, Ye are more, which relates to the comparison of number, but ye are of more value, that is, of greater estimation in the sight of God.

Or, by the head of each of the faithful, you must understand a conversation meet for Christ, but by his hair, the works of bodily mortification which are numbered by God, and are worthy of the Divine regard.

(pluris estis) Now I ask the Arians, if God, as if disdaining to make all other things, made only His Son, but deputed all things to His Son; how is it that He extends His providence even to such trifling things as our hair, and the sparrows? For upon whatever things He exercises His providence, of these is He the Creator by His own word.
