Initially, the settlers of Worthington were English, but they were soon followed by German and Irish families. At first most of the residents of Worthington traveled to St. Francis Church in Dyersville, while some went to Saint Martin's Church in Cascade, Iowa because services there were conducted in English.
In 1862 Rev. Anton Kortenkamp (1834-1889) arrived in Dyersville, Iowa. He would attend to the needs of Worthington Catholics until 1875. By 1868 the population of Worthington had grown large enough that Kortenkamp had decided the time had come for a new parish to be established in Worthington. Construction of a brick building was soon begun and the new parish was dedicated to Saint Paul. The cornerstone of this first building had the inscription, "Romisch Catholische, St. Paulus Kirche, Gebaut 1 Nov. 1868." The new church took about four years to complete.
