Tyng has an interesting story. In 1854, he took over as pastor of the Church of the Epiphany in Philadelphia when his father retired. But Dudley, unlike his more moderate father, was a committed abolitionist. Just two years later, his preaching against slavery resulted in his being forced to resign. With a few loyal followers, he then organized the Church of the Covenant in that same city. In 1858, he held a rally for fathers and sons, and 5,000 attended. He concluded the event with this: "I would rather this right arm be amputated at the trunk than that I should come short of my duty to you in delivering God's message."

It was only two weeks later that Tyng, visiting a congregant's farm, and watching the thrasher work, got his sleeve caught in that machine. His arm was pulled into the thrasher and torn from its socket. Just a few days later, his arm was amputated at the shoulder. Before he died days a few days later, he told his father to "stand up for Jesus." His final words soon became a popular hymn that is still sung today: "Stand Up, Stand Up For Jesus."
