Credo quia absurdum is a Latin phrase that means "I believe because it is absurd", originally misattributed to Tertullian in his De Carne Christi. It is believed to be a paraphrasing of Tertullian's "prorsus credibile est, quia ineptum est" which means "it is completely credible because it is unsuitable", or "certum est, quia impossibile" which means "it is certain because it is impossible". Early modern, Protestant and Enlightenment rhetoric against Catholicism and religion more broadly resulted in this phrase being changed to "I believe because it is absurd", displaced from its original anti-Marcionite context into a personally religious one.[1] Tertullian's phrase originated in a rebuttal to Marcion's view that a human death for the divine Son of God would be paradoxical and thus ought to be rejected.[2]
