"solitude of his dungeon he saw more clearly what he had done. He thought of the courage and fidelity of Huss, and in contrast pondered upon his own denial of the truth. He thought of the divine Master whom he had pledged himself to serve, and who for his sake endured the death of the cross. Before his retraction he had found comfort, amid all his sufferings, in the assurance of God's favor; but now remorse and doubts tortured his soul. He knew that still other retractions must be made before he could be at peace with Rome. The path upon which he was entering could end only in complete apostasy. His resolution was taken: To escape a brief period of suffering he would not deny his Lord. GC 111.2"
"And Peter remembered the word of Jesus, which said unto him, Before the cock crow, thou shalt deny me thrice. And he went out, and wept bitterly."
Both passages describe a person regretting their denial of faith under pressure. Jerome's experience mirrors Peter's denial of Christ, making this a valid thematic parallel.
"Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God."
Both passages involve considering Jesus' sacrifice on the cross as motivation to remain faithful. Jerome reflects on Christ's suffering, similar to the encouragement in Hebrews 12:2.
