I have a soft spot for
St Robert Bellarmine, in part because of his consideration of the relationship between science and Christian faith outlined below, and in part because of the affinity of his stature in the Catholic Church of his time to that of Cardinal Joseph Ratzinger when he was Prefect of the Congregation for the Doctrine of the Faith. The account below dates from some work I did in 1997. The principle source for the thinking of Robert Bellarmine is a two volume biography by written by William Brodrick and published in 1928.
In April 1615, St. Robert
Bellarmine wrote a letter to the author of a book which had defended the
Copernican view of the universe, clearly addressing the letter to Galileo as
well.
St. Robert Bellarmine fulfilled a
role in the Church of his time similar to that of Cardinal Ratzinger in our own
time (ie in 1997).
He was a man of great intellect
and profound devotion.
He was well
informed about the state of contemporary scientific endeavour and seems to have
had quite cordial communications with Galileo.
His letter is strikingly modern, and very concisely presents an answer
to the debate as it had come to be presented.
“..It seems to
me that your Reverence and Signor Galileo act prudently when you content
yourselves with speaking hypothetically and not absolutely, as I have always
understood Copernicus spoke..”
This is a reference to the fact
that the Copernican view was an interpretation of astronomical
observations.
At least one other
successful interpretation was possible at the time, and it is in this sense that the
Copernican view represented a “hypothetical” rather than an “absolute”
claim.
To accept it as a “hypothesis” in
this sense was quite a different thing than accepting it as being the way
things really were.
“..If there
were a real proof that the Sun is in the centre of the universe ... and that
the Sun does not go round the Earth but the Earth round the Sun, then we should
have to proceed with great circumspection in explaining the passages of
Scripture which appear to teach the contrary, and we should rather have to say
that we did not understand them than declare an opinion to be false which is
proved to be true..”
This is the critical passage in
the letter.
Underlying it is the
conviction that the results of scientific study and the content of Christian
faith are in harmony with each other.
When science can offer convincing proof, then it is necessary to look
again at the way in which Scripture is understood.
“But I do not
think there is any such proof since none has been shown to me..I believe that
the first demonstration (i.e. that the
Copernican view is a workable hypothesis) may exist, but I have grave
doubts about the second (i.e. the
existence of proof that the Copernican view is the way things really are);
and in the case of doubt one may not abandon the Holy Scriptures as expounded
by the holy Fathers..”
This is an important balancing of
the previously expressed willingness to look again at the way in which
Scripture is understood.
In the
seventeenth century there really was not any absolute evidence of the earth’s movement
through space.
In the twentieth century
there is, and, if he were alive today, St. Robert Bellarmine would accept that
proof and be willing to understand Scripture differently as a consequence.
The decree of 1616, in St. Robert
Bellarmine’s account of how it was notified by him to Galileo, was that the
Copernican view “is contrary to Holy Scriptures and therefore cannot be
defended or held”.
In the sense of St.
Robert Bellarmine’s letter, this decree still allowed discussion of Copernicus
view as a working hypothesis, and this seems to have been the way in which both
Bellarmine and Galileo understood it.
Seen in this context, the decree
of 1616 is not unreasonable. However,
history has come to see it as a defining moment in the development of a gulf
between science and Christian faith, with particular ill-feeling being directed
at the Catholic Church. This might be
accounted for by the stricter interpretation given to the decree by some
churchmen and by the controversialist stance taken by Galileo, both of which
combined to lead to Galileo’s trial in 1633. But the inappropriate opposition of science and
Scripture around which the whole affair developed did not find support amongst
the best Catholic thinkers of the time.
