Timothy Cardinal Dolan of the Archdiocese of New York formally opened the Cause for Canonization of Servant of God Father Paul of Graymoor on Tuesday, September 22, 2015 in New York City. The Father Paul of Graymoor Guild was established in 2016 as a central information source about the status of the cause for Father Paul of Graymoor's canonization. In March 2017, the diocesan phase of the process was closed, and Wattson's collected writings were forwarded to the Congregation for the Causes of Saints in Rome.
