 Princeton professor Robert George argued that Catholics should accept that Martin believes in the Church's teaching on homosexuality.In 2017, Archbishop Charles Chaput of Philadelphia described many of the attacks against Father Martin as "bitterness" that is "unjust and unwarranted," but called 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."
