Areithiau (discorsi)
Cymraeg. Mae'r Gorllewin wedi hir cael ei beryglu gan atgasedd hwn i'r cwestiynau sy'n sail ei rhesymoledd, a dim ond yn dioddef niwed mawr a thrwy hynny. Y dewrder i ymgysylltu ehangder cyfan o reswm, ac nid gwrthod ei fawredd - dyma'r rhaglen diwinyddiaeth seilio mewn ffydd Beiblaidd mynd i mewn i'r dadleuon o'n hamser â hwy.
"Peidio â weithredu'n rhesymol, peidio â gweithredu gyda logos, yn groes i natur Duw", meddai Manuel II, yn ôl ei ddealltwriaeth Gristnogol o Dduw, mewn ymateb i'w interlocutor Persian. Y mae i hyn logos mawr, i ehangder hwn o reswm, ein bod yn gwahodd ein partneriaid yn y ddeialog o ddiwylliannau. I ailddarganfod barhaus fydd tasg mawr y brifysgol.

English. The West has long been endangered by this aversion to the questions which underlie its rationality, and can only suffer great harm thereby. The courage to engage the whole breadth of reason, and not the denial of its grandeur - this is the programme with which a theology grounded in Biblical faith enters into the debates of our time. "Not to act reasonably, not to act with logos, is contrary to the nature of God", said Manuel II, according to his Christian understanding of God, in response to his Persian interlocutor. It is to this great logos, to this breadth of reason, that we invite our partners in the dialogue of cultures. To rediscover it constantly is the great task of the university.
