Archbishop Charles Chaput of Philadelphia stated that “due to the confusion caused by his statements and activities regarding same-sex related (LGBT) issues, I find it necessary to emphasize that Father Martin does not speak with authority on behalf of the Church, and to caution the faithful about some of his statements.” Archbishop Chaput has also described many of the attacks against Martin as "bitterness" that is "unjust and unwarranted," while still calling for "serious, legitimate criticism" of the book's "perceived ambiguities" and inadequacies. Chaput argued that dealing with the substantive issues frankly "is the only way an honest discussion can be had." In 2019 Chaput again criticized the "bitter personal attacks" that have been made against Martin, calling them "inexcusable and unChristian." While stating that many of Martin's efforts to accompany and support people with same-sex attraction have been laudable, Chaput also criticized Martin for "a pattern of ambiguity in his teachings," and for asking the Church to modify its teaching that same-sex attraction is "objectively disordered." Chaput stated: "The suggestion that the wisdom of the Church, rooted in the Word of God and centuries of human experience, is somehow cruel or misguided does grave harm to her mission." Martin replied that same-sex relations and same-sex marriage "are both impermissible (and immoral) under Church teaching," and that the reason he does not focus on this "is that LGBT Catholics have heard this repeatedly." Bishop Thomas Paprocki and bishop Richard Stika supported Chaput's column. Bishop Paprocki described Martin's attitude as "deeply scandalous in the sense of leading people to believe that wrongful behavior is not sinful."
