It is urgent therefore "that we rediscover, in a new way, human rationality, open to the light of the divine Logos and its perfect revelation that is Jesus Christ, the Son of God made flesh". In other words, according to the Holy Father, "when it is genuine, the Christian faith does not demean man’s freedom and reason; so why should faith and reason be scared of each other if by meeting and talking with each other they can make the most of themselves? Faith presumes and perfects reason, and reason, enlightened by faith, finds the strength to rise to the knowledge of God and to spiritual reality". So human reason "loses nothing in opening up to the contents of the faith; actually such contents demand that it adheres to it freely and consciously". Saint Thomas "managed to establish a fruitful exchange with the Arab and Hebrew philosophy of his time, so as to be regarded as an ever-relevant master of dialogue with different cultures and religions". He, added the Pope, "skilfully showed that admirable Christian synthesis between faith and reason that for the Western civilisation is a valuable heritage to be drawn on, even today, to effectively talk with the great cultural and religious traditions of the east and south of the world". "Let’s pray he concluded for Christians to be able to express the reasonableness of their faith and testify it in love-inspired dialogue".
