After death
Three new publications on Bishop John Joseph have been published since the bishop's death. "A Peaceful Struggle" is a compilation of the bishop's writings on matters related to justice and peace. The 197-page book was compiled by the Faisalabad diocesan human rights office, led by Father Khalid Rashid Asi. A translation of the English-language book into Urdu has also been published. The third book, "Sermons in Blood," is a 110-page book written by labor activist Gulzar Wafa Chaudhry. Chaudhry attempts to keep alive the revolutionary spirit that Bishop Joseph tried to initiate in protest at the situation of Christians and other religious minority communities in Pakistan. A film showing Bishop John Joseph's struggles for minority rights was screened at the South Asian film festival in Kathmandu October 4–7, 2001. The 45-minute documentary "A Sun Sets in" was produced by Waseem Anthony and showed the life of the late Bishop, the first Punjabi bishop, and his struggle for Pakistani Catholics. The Bishop John Joseph Memorial Hall in Darulaloom Jamia Rehmania madrassa in Faisalabad, was inaugurated on March 31, 2007. Bishop Joseph Coutts was present during the opening. No other Islamic seminary in the country has a building named after a Catholic priest. On Bishop John Joseph's advice Mr. Aftab Alexander Mughal and Mr. Peter Jacob wrote a book, Section 295 C, Pakistan Penal Code – Study of the History, Effects and Cases under Blasphemy Laws in Pakistan, which was published in 1995.
