Might want to stick to English.
CREDO QUIA ABSURDUM - I believe because it is absurd (or impossible). A phrase attributed (maybe falsely) to Tertullian (160-220), by which is meant that a Christian believer is not scandalized at the apparent absurdity or impossibility of such revealed mysteries as the Incarnation, that God became man, or the Real Presence, that Christ is truly present under the Eucharist species.
Why is one miracle less likely than another?
