In 2017, the Italian Catholic priest Antonio Spadaro tweeted: "Theology is not #Mathematics. 2 + 2 in #Theology can make 5. Because it has to do with #God and real #life of #people..." In defence of the priest, Traditionalist Catholics stated that Spadaro's remark was referring to alleged contradictions among interpretations of the apostolic exhortation "Amoris laetitia" (2016)—for divorced-remarried Catholics returning to the Church—and the doctrines of Marriage in the Catholic Church. That a person can freely act in contradiction to Catholic doctrine if he or she felt that God allowed that action—despite the moral and theological contradictions inherent to the action. That Spadaro's "two plus two equal five" comments refer to the Church philosophy that human reason is insufficient for the full comprehension of God. That Spadaro was much like the cynical Rex Mottram character in the novel "Brideshead Revisited" (1945), by Evelyn Waugh, wherein Mottram, during his catechesis (becoming Catholic to marry a Catholic) is indifferent to ascertaining any aspect of Catholicism; Mottram attributes moral and theological contradictions to personal sinfulness.
