From The Sadness of Christ:
Unless peradventure he spake these words: ‘Arise and let us go,’ because he would not have
them shrink away for fear, but rather to make them go forth and boldly meet their enemies, like as he did
himself, who drew not backward another way from them, but incontinent after these words spoken went
willingly himself towards them which maliciously came to murder him.
Saint Thomas was of a scholarly turn of mind, and boldly confronting enemies did not come naturally to him, but he did so nonetheless.
