On September 4, 1840, Neumann wrote to Father Prost, the Redemptorists' superior in America, asking for admission to the Congregation of the Most Holy Redeemer. Receiving a favorable reply from Prost on September 16, Neumann immediately wrote to Bishop John Hughes, acquainting him with his desire to enter the Redemptorists and asking him to send one or more priests to take over the churches outside Buffalo. Unbeknownst to Neumann, the bishop was on visitation, so no reply was forthcoming. Still, leaving the negotiations with Hughes in Pax and Prost's hands as they advised, Neumann left the Buffalo area on October 8 or 9, 1840. When Hughes learned of the matter, he was not at all inclined to allow a pastor of Neumann's caliber to depart from his diocese, but Prost later wrote, "I appealed to canon law and pointed out that I could not refuse to accept him, even if I wished to. The Most Reverend Bishop was obliged to yield." His brother, Wenzel, stayed to gather up the few belongings that Neumann possessed in the various mission stations and resolved to follow his brother and become a lay brother of the Congregation of the Most Holy Redeemer.
