Robert Bellarmine

Robert Bellarmine (Italian: Roberto Francesco Romolo Bellarmino) (1542–1621) was an Italian Jesuit and a Cardinal of the Roman Catholic Church. He was one of the most important cardinals of the Catholic Reformation. He was canonized in 1930 and is a saint and a Doctor of the Church.

In 1616, Cardinal Bellarmine summoned Galileo Galilei and notified him of a forthcoming decree of the Congregation of the Index condemning the Copernican doctrine of the mobility of the Earth and the immobility of the Sun, and ordered Galileo to abandon the theory. Galileo agreed to do so at the time, but returned to the matter in 1632.

When Galileo was being examined in 1633 by Cardinal Sigismondo Gioioso, Galileo reminded the Cardinal that Robert Bellarmine had warned Galileo that the Copernican view was incompatible with Church doctrine over a decade before. Gioioso did not believe Galileo.
