Bellarmine was made a cardinal by Pope Clement VIII on the grounds that “he had not his equal for learning.” While he occupied apartments in the Vatican, Bellarmine relaxed none of his former austerities. He limited his household expenses to what was barely essential, eating only the food available to the poor. He was known to have ransomed a soldier who had deserted from the army and he used the hangings of his rooms to clothe poor people, remarking, “The walls won’t catch cold.” Among many activities, Bellarmine became theologian to Pope Clement VIII, preparing two catechisms which have had great influence in the Church. The last major controversy of Bellarmine’s life came in 1616 when he had to admonish his friend Galileo, whom he admired. He delivered the admonition on behalf of the Holy Office, which had decided that the heliocentric theory of Copernicus was contrary to Scripture. The admonition amounted to a caution against putting forward—other than as a hypothesis—theories not yet fully proven. This shows that saints are not infallible.
