"A Berber, born in 354 at Thagaste (now Souk-Ahras) in Africa... The exceptional brilliance of his works (The City of God, The Confessions), his contradictory nature, his desire to bring together faith and intelligence, classical and Christian civilization, the old wine and the new — these deliberate efforts made him in some ways a rationalist. For him, faith came first: but he nevertheless declared 'Credo ut intelligam' — 'I believe in order to understand.' He also said 'Si fallor, sum' — 'If I am mistaken, I exist' — and 'Si dubitat, vivit' — 'If he doubts, he is alive'... Posterity undoubtedly concentrated its attention on St Augustine as a theologian, and on what he wrote about predestination. But Augustinianism gave Western Christianity some of its colour and its ability to adapt and debate — if only by insisting on the vital need to embrace the faith in full awareness, after deep personnal reflection, and with the will to act accordingly."
