Although animal advocates implored Ratzinger to reiterate his views on animal welfare after he became Pope, he never did so. Francis, by contrast, appears to have been referring to factory-farmed animals when he spoke, in The Joy of the Gospel, of “weak and defenseless beings who are frequently at the mercy of economic interests or indiscriminate exploitation.”
尽管动物保护主义者在拉辛格成为教皇后恳请他重申其关于动物福利的观点，但他从未这样做。相反，方济各似乎在其《福音书的快乐》（The Joy of the Gospel）中便将工厂化饲养的动物称为“孱弱的、毫无防备的生物，任由经济利益无差别剥削宰割。”
