ermm, you mean heliocentrism? Geocentrism was indeed never declared a
heresy, and I don't think anyone ever argued that
was never defined as heresy within the Catholic
> Church, either before Bruno after Bruno.
Well, what I said can in all fairness be read like this. As the point
was about Bruno, I didn't feel the need to be overly technical when
describing what happened afterwards.
For the Bruno trial the case is clear, whether or not one argues that
heliocenrism became a formal heresy later often boils down to an issue
of semantics and extremely technical canon law distinctions.
What is clear of course is that Galileo was convicted of "something".
What is equally clear is that his books, and also other books endorsing
variants of the Copernican system came on the Index. It is equally clear
that they were removed from the Index between 1718 and 1835, step by step.
So the question is how these two can be reconciled - or maybe even more
broadly, the Council of Trent with the 2. Vatican Council. There are
several possible answers
a) Galileo was correctly convicted for the heresy of heliocentrism, and
the Church has now realized that was a bad law and changed it
b) the Galileo trial was a mistake in law. The heliocentrism he espoused
was not a heresy then, and he should therefore not have been convicted.
The law did not need changing, only its application had been faulty
c) Galileo was rightfully convicted under the law as it then was, and
the law did not, and need not changing. That's obviously the more
difficult view to take, and it can take at least 3 different version
c.1: heliocentrism is and was heretical. A position only
held by a couple of fringe theologians these days
c.2: he wasn't really convicted because of heliocentrism
c2 can again be subdivided:
c.1.1 he was convicted of something that looks like holding heretical
heliocentric views, but really wasn't, once you look more closely.
There are again numerous variations of this. One is that he was only
convicted of a specific version of heliocentrism that was heretical, a
specific version of Copernicanism that nobody any longer holds. Or it
was not the content of the theory, but his "ontologising" what should
have been an epistemological issue (this line looks at the compromise he
was offered). Or his mistake was not the substance of the theory, but
that he proposed it with insufficient evidence, which is on procedural
grounds the wrong way to challenge established teaching, so the heresy
is one of general disobedience. And of course now we have the evidence.
So heliocentrism isn't heretical as such, just heliocentrism without
enough evidence. Or he wasn't convicted of a formal heresy, but
something less serious, like a suspected heresy.
c.1.2.: the trial had nothing to do with heliocentrism at all, and he
was convicted of another heresy altogether. A candidate for this is the
idea that he was "really" convicted of atomism, which he may have
endorsed in "The Assayer" - that is a minority view among some academics
The church obviously does not like a),and has used some ingenuity to
argue for various of the alternatives, from individual theologians and
church historians right to the top. John Paul II seems to have veered
towards b), though I suspect in his heart of hearts he knew that as a
matter of history, rather than canon law, a) probably is closest to how
the actors understood it at the time. Benedict seemed to go for one or
several of the c.1.1 versions. John Paul set up the commission of course
to look at the Galileo affair, but after 10 years of (regrettably
secret) debate, what it delivered was meh... If anything it muddled the
water further.
Some of the data that needs to be accommodated, emphasis added by me
The Qualifiers, unanimously, ruled in 1616 that:
------------------------------------------------------
Assessment made at the Holy Office, Rome, Wednesday, 24 February 1616,
in the presence of the Father Theologians signed below.
Proposition to be assessed:
(1) The sun is the center of the world and completely devoid of
local motion.
Assessment: All said that this proposition is foolish and absurd in
philosophy, and FORMALLY HERETICAL since it explicitly contradicts many
places the sense of Holy Scripture, according to the literal meaning of
the words and according to the common interpretation and understanding
of the Holy Fathers and the doctors of theology.
(2) The earth is not the center of the world, nor motionless, but
it moves as a whole and also with diurnal motion.
Assessment: All said that this proposition receives the same
judgement in philosophy and that in regard to theological truth it is at
least ERRONEOUS IN FAITH
------------------------------------------------------------------
So this clearly reads like an official denouncement of heliocentrism.
Why can one argue that it nonetheless is not a smoking gun? Two reasons:
First, a decision of the Qualifiers is not technically binding on the
Church - but as a body directly appointed by the Pope it is highly
persuasive also in canon law as an interpretation of existing rules,
though not creation of a new one. Unlike the Bruno case, it is a
sufficient basis to bring charges.
The second is the difference in the analysis between 1 and 2. 1 is
declared a formal heresy, 2 merely "at least erroneous in faith" -
leaving open if it is a formal heresy.
Since "heliocentrism" normally requires 1 and 2, one can just about
argue that this means "heliocentrism" isn't a formal heresy, just the
belief that the sun is the center of the world and fixed - but that is
for obvious reasons a bit odd
In the next step, there is the the official decree of the Index from 5th
of March 1616) which bans a whole range of books that endorse the
Copernican system
This is more guarded than the assessment It declared that the
Copernican theses were “false and altogether contrary to Holy Scripture”
but made no mention of heresy explicitly, so it is ambiguous what that
means, in canon law. Copernicus’s book was to be “suspended until
corrected”, and again, that leaves ample room for interpretation
depending what you think the corrections were supposed to do.
"At the palace of the usual residence of the said Most Illustrious Lord
Cardinal Bellarmine and in the chambers of His Most Illustrious
Lordship, and fully in the presence of the Reverend Father Michelangelo
Segizzi of Lodi, O. P. and Commissary General of the Holy Office, having
summoned the above-mentioned Galileo before himself, the same Most
Illustrious Lord Cardinal warned Galileo that the above-mentioned
opinion was erroneous and that he should abandon it; and thereafter,
indeed immediately, before me and witnesses, the Most Illustrious Lord
Cardinal himself being also present still, the aforesaid Father
Commissary, in the name of His Holiness the Pope and the whole
Congregation of the Holy Office, ordered and enjoined the said Galileo,
who was himself still present, to abandon completely the above-mentioned
opinion that the sun stands still at the center of the world and the
earth moves, and henceforth not to hold, teach, or defend it in any way
whatever, either orally or in writing; otherwise the Holy Office would
start proceedings against him. The same Galileo acquiesced in this
injunction and promised to obey "
and finally from the verdict:
"We say, pronounce, sentence, and declare that you, the above-mentioned
Galileo, because of the things deduced in the trial and confessed by you
as above, have rendered yourself according to this Holy Office
vehemently suspected of heresy, namely of having held and believed a
doctine which is false and contrary to the divine and Holy Scripture:
that the sun is the center of the world and does not move from east to
west, and the earth moves and is not the center of the world, and that
one may hold and defend as probable an opinion after it has been
declared and defined contrary to Holy Scripture. Consequently you have
incurred all the censures and penalties imposed and promulgated by the
sacred canons and all particular and general laws against such
delinquents. We are willing to absolve you from them provided that
first, with a sincere heart and unfeigned faith, in front of us you
abjure, curse, and detest the above-mentioned errors and heresies, and
every other error and heresy contrary to the Catholic and Apostolic
Church, in the manner and form we will prescribe to you."
Now, it depends a bit if you think of this as a historian, lawyer or
theologian, but apart from the noted outliers above, every answer seems
to have some problems with some of the things we know, andeach of them
has some arguments in its favour. There are lots of inconsistencies in
the events as they unfolded, again all leave room for interpretation -
What shall we make of it e.g. that Bellamy certified, on Galileo's own
request, and after meeting with him in private that he had “only been
notified” of the Pope’s declaration that the Copernican doctrine was
contrary to Scripture and therefore “cannot be defended or held” -
which, as Galileo did not reject that notification, should have been the
end of it - and yet in 1632 we see that he has been served with an
injunction.
My own, tentative view is
a) this is a mess and will remain one. Part of it is that the catholic
church was on the defense here from the word go. The initial
condemnation was triggered by the reformation which ironically made the
catholic church look wishy washy, modernist and liberal, and hence lead
to a conservative backlash, and then in a reversal of roles 19th and
20th century liberal protestants using the affair to argue that the RCC
was hopelessly reactionary, anti-science and outmoded. Being
wrong-footed both times, it chose to fight battles it really should not
and need not have to
b) while from an abstract legal -doctrinal perspective, we tend to look
for neat, consistent solutions, history is much more muddled than that,
and especially the 16th and 17th century papacy was by far not as
organized, coherent, legalistic etc as it is sometimes depicted. Even
modern secular legal systems don;t always make coherent sense, 17th
century canon law in a highly politicized environment def didn't
c) the trial, but not the earlier injunctions, violated procedural rules
or a pretty big scale.
d) Pope Urban sifted his attitude to Galileo's work significantly
between 1616 and 1630 - however, the issue for him is not primarily
heliocentrism, but the question whether God would have been free to set
up the world otherwise, something that contradicts the way Galileo
presents the theory
e) however, for a number of reasons that may be more political than
substantial (including a big Swedish army), the verdict against Galileo
does not make this explicit, and as worded condemns heliocentrism
instead at the very least as "suspected heresy" (note, "suspected heresy
is not a something that may or may not turn out to be a heresy, but a
less serious form of heresy)
