From The Sadness of Christ:
For he meant not that they should in no case once shrink at death, but
that they should not so shrink and flee from temporal death, that by forsaking the faith, they should fall
into endless death for ever. Who though he would have his soldiers to be bold and therewithal discreet,
requireth not yet to have them neither like blocks nor madmen. For as he hath a strong courageous heart
that never shrinketh patiently to suffer pain, so he that feeleth none, is like a very block without any
sense at all. It were a mad part for a man not to fear to have his flesh cut, and yet should no wise man for
any dread of pain be withdrawn from his godly purpose, and so, by the refusal of a small pain, purchase
himself a much greater.
Saint Thomas More in the tower clearly feared the almost certain death that awaited him, but that fear did not alter his purpose.
“And will you come to hell with me for fellowship?”
