Envious colleagues denounced Pantaleon to the emperor during the Diocletian persecution. But he yearned to prove his fidelity to the Faith by shedding his blood for it. The emperor wished to save him and sought to persuade him to apostasy, but Pantaleon replied “the God whom I adore is Jesus Christ. He created heaven and earth, He raised the dead to life, made the blind see and healed the sick, all through the power of His word. Your idols are dead, they cannot do anything.” As proof that Christ is the true God, Pantaleon healed a paralytic saying, "In the name of Jesus, the Son of God, I command thee to rise and be well."
