In 1992 after 13 years deliberation and 359 years

Inquisition ruled that Galileo could not prove 'beyond doubt' that the
Earth orbits the Sun, so they could not reinterpret scriptures implying
otherwise.

Galileo proposed that a falling body would fall with a uniform
acceleration, as long as the resistance of the medium through
which it was falling remained negligible, or in the limiting case
of its falling through a vacuum.[125] He also derived the correct
kinematical law for the distance travelled during a uniform
acceleration starting from rest—namely, that it is proportional to
the square of the elapsed time ( d ∝ t 2 ).[126] However, in
neither case were these discoveries entirely original. The timesquared law for uniformly accelerated change was already
known to Nicole Oresme in the 14th century,[127] and Domingo
de Soto, in the 16th, had suggested that bodies falling through
a homogeneous medium would be uniformly accelerated.[128]
Galileo expressed the time-squared law using geometrical
constructions and mathematically precise words, adhering to
the standards of the day. (It remained for others to re-express
the law in algebraic terms).
He also concluded that objects retain their velocity unless a
force—often friction—acts upon them, refuting the generally
accepted Aristotelian hypothesis that objects "naturally" slow
down and stop unless a force acts upon them (philosophical
ideas relating to inertia had been proposed by John Philoponus
centuries earlier, as had Jean Buridan, and according to
Joseph Needham, Mo Tzu had proposed it centuries before
either of them, but this was the first time that it had been
mathematically expressed, verified experimentally, and
introduced the idea of frictional force, the key breakthrough in
validating inertia). Galileo's Principle of Inertia stated: "A body
moving on a level surface will continue in the same direction at
constant speed unless disturbed." This principle was
incorporated into Newton's laws of motion (first law).

In the end, Cardinal Bellarmine, acting on
directives from the Inquisition, delivered
him an order not to "hold or defend" the
idea that the Earth moves and the Sun
stands still at the centre.
By 1616 the attacks on Galileo had
reached a head, and he tried to
persuade the Church not to ban his
conclusions that the Earth rotates
around the Sun
In the end Evidence was the final
arbiter and the separation of Science
from both Philosophy and Religion took
place.
Galileo’s case was the turning point
and a major justification for his
description as
“The Father of Science".
By 1616 the attacks on Galileo had
reached a head, and he went to Rome
to try to persuade the Church
authorities not to ban his ideas.
Although he tried to remain loyal to the

interpretation,
clearly
contributed to the rejection of blind

both
philosophical and religious, in matters
of science.
History
http://en.wikipedia.org/wiki/File:Phases-of-Venus.svg
Diagram of the orbit of Venus in relationship to the Earth.
The first known observations of the full planetary phases of Venus were by
Galileo at the end of 1610 (though not published until 1613). Using a
telescope, Galileo was able to observe Venus going through a full set of
phases, something prohibited by the Ptolemaic system (which would never
allow Venus to be fully lit from the perspective of the Earth or more than
semi-circular). This observation essentially ruled out the Ptolemaic system,
and was compatible only with the Copernican system and the Tychonic
system and other geoheliocentric models such as the Capellan and Riccioli's
extended Capellan model.

GALILEAN EQUATION

It is hard for us to appreciate today how
strange that idea sounded in 1638, barely 50
years after the introduction of algebraic
notation by Vieta. To proclaim algebra the
UNIVERSAL language of science, would
sound today like proclaiming Esperanto the
language of economics. Why would Nature
agree to speak Algebra? of all languages?
But you can't argue with success. The
distance traveled by an object turned out
indeed to be proportional to the square of the
time.

A Just Condemnation Recognized by Many
Galileo at the process of the Inquistition
Prof. Nicola Cabibbo, ex-president of the Italian Institute of Nuclear
Physics summarized the case: “Galileo was not condemned for his
scientific theses, but because he wanted to formulate theology” (19).
Therefore, there is no reason to say that the Inquisition and the Church
erred when they condemned Galileo. There is even less reason to say
that such condemnation demonstrates the Church is not infallible. Also,
the hasty consequence that the door should open to a scientific
interpretation of Scripture is not conclusive.
Science lacks the competence to interpret Sacred Scripture; if it were
otherwise, we would end by denying all the revealed mysteries, which
are far beyond the capacity of physical and experimental sciences to
explain. To introduce scientific criticism in questions of Faith would be to
reduce them to human stature, which is the same as denying them. 17.

A Just Condemnation Recognized by Many
The Holy Inquisition, therefore, acted correctly in condemning Galileo.
That action was consistent with its mission of guarding the integrity of
the Catholic Faith. It was justly defending the Catholic Theology and
Philosophy attacked by Galileo Galilei.
In a speech delivered in Parma, Italy, March 15, 1990, even Cardinal
Joseph Ratzinger endorsed the opinion of philosopher P. Feyerabend
against Galileo. Ratzinger stated: “At the time of Galileo the Church
remained much more faithful to reason than Galileo himself. The
process against Galileo was reasonable and just” (17). Italian author and
journalist Vittorio Messori was also critical of Galileo: “Galileo was not
condemned for the things he said, but for the way he said them. He
made statements with a sectarian intolerance, like a ‘missionary’ of a
new gospel …. Since he did not have objective evidence for what he
said, the things he said in his private letters to those men [of the Roman
College] made him suspect of dogmatism supporting the new religion of
science. One who would not immediately accept the entire Copernican
system was ‘an imbecile with his head in the clouds,’ ‘a stain upon
mankind,’ ‘a child who never grew up,’ and so on. At depth the certainty
of being infallible seemed to belong more to him than to the religious
authority” (18).
Galileo at the process of the Inquistition
The idea that the Church had acted “more rationally” in its dealings with
Galileo was given its most detailed defence by Feyerabend in his talk to the
Crakow Conference of 24-27 May 1984, entitled Galileo and the Tyranny of
Truth (reprinted in Farewell to Reason). A severe treatment of Poupard’s
(non-)resolution can be found in Annibale Fantoli’s work, particularly his
Galileo and the Catholic Church: A Critique of the “Closure” of the Galileo
Commission’s Work (Specola Vaticana, 2002). I myself have discussed why
Feyerabend’s argument fails here (with more detail here), but the basic
point is that the interpretive principle arrived at by Bellarmine in his Letter to
Foscarini rendered any thought of development in the Church’s attitude
towards heliocentrism or geokineticism impossible due to his insistence that
the Bible passages ostensibly contradicting either were to be considered a
matter of faith ex parte dicentis. Feyerabend appears to have been
unaware of this, given that he remarked that Ratzinger’s position was
“similar” to Bellarmine’s when instead only the instrumentalism of the early
parts of Bellarmine’s letter are supported by his caution, not the later
declaration that all Scriptural passages are authored by the Holy Spirit (with
its consequences). Both Feyerabend and Ratzinger were mistaken on
this issue, then, since calling this approach - leading invariably to
stagnation in astronomy and physics, as Galileo and senior Jesuits
like Grienberger foresaw - more rational than Galileo’s is absurd. Like
most others who have come into contact with the Galileo Affair, they have
simplified the events to fit their own preconceptions.
The Pope, the ex-Grand Inquisitor
Lest you think that our new Pope is not the sort to burn people at the stake, in
1997 Ratzinger said that Buddhism is ‘autoerotic spirituality’ that offers
‘transcendence without imposing concrete religious obligations’. 'Hinduism,' he
added, offers ‘false hope’; it guarantees ‘purification’ based on a ‘morally cruel’
concept of reincarnation resembling ‘a continuous circle of hell’. The Cardinal
predicted Buddhism would replace Marxism as the Catholic Church’s main
enemy this century. Barbequed Buddhists anyone?
Pope Ratzinger believes that only the Catholic Chutch is a true church. That
make all other Christian denominations fake churches, in Ratzinger's eyes,
and Ratzinger believes that as Pope, his eyes are the same as the eyes of
God. Posted 4/22/2005 8:26 AM - email it
Psalms
93:1;
96:10;
104:5,
1Chronicles 16:30 and Ecclesiastes
1:4,5 speak of the (in some sense)
"firm" and "established" position of the
earth. Galileo defended heliocentrism,
and claimed it was not contrary to
those Scripture passages.
The writers of the Scripture wrote
from the perspective of the
terrestrial world, and from that
vantage point the sun does rise
and set. In fact, it is the earth's
rotation
which
gives
the
impression of the sun in motion
across the sky.
The decree did not prevent Galileo
from
discussing
heliocentrism
hypothetically. For the next several
years Galileo stayed well away from
the controversy.

Made In: Florence
In this book Galileo compared the Earth-centred Ptolemaic and
Sun-centred Copernican systems. He wrote in Italian, rather than
the Latin of scholars, to reach a wider audience.
Galileo clearly favoured the Copernican system, but he misjudged
the reception the book would receive from the Catholic Church. He
was tried for heresy, forced to recant his ideas, and ended his life
under house imprisonment.
He took Augustine's position on
Scripture: not to take every passage
literally, particularly when the scripture
in question is a book of poetry and
songs, not a book of instructions or
history.
This lead to the separation of Science
from both Philosophy and Religion,
a major justification for his description
as “The Father of Science".

Doctrine of the Faith, the official organization that was known prior to 1908 as
the Sacred Congregation for the Universal Inquisition. That's right folks,
Ratzinger was prior to becoming Pope, the Grand Inquisitor.
The Sacred Congregation of the Universal Inquisition was founded in 1542 by
Pope Paul III, its duties originally included tourturing people and burning
people at the stake. The Pope had thus been the titular head of the
organization that had persecuted Gslileo. Ratzinger was still fighting the good
fight in 1990. Of course the Church was right to persceute Galileo for saying
the earth circled the sun. Galileo was irrational, even though we are now
foced to admit that those Catholic Churchmen who refused to look throuugh
Galileo's telescope and pronunced him a heritic did make a mistake.

simplified the events to fit their own preconceptions.
The Pope, the ex-Grand Inquisitor
Lest you think that our new Pope is not the sort to burn people at the stake, in
1997 Ratzinger said that Buddhism is ‘autoerotic spirituality’ that offers
‘transcendence without imposing concrete religious obligations’. 'Hinduism,' he
added, offers ‘false hope’; it guarantees ‘purification’ based on a ‘morally cruel’
concept of reincarnation resembling ‘a continuous circle of hell’. The Cardinal
predicted Buddhism would replace Marxism as the Catholic Church’s main
enemy this century. Barbequed Buddhists anyone?
Pope Ratzinger believes that only the Catholic Chutch is a true church. That
make all other Christian denominations fake churches, in Ratzinger's eyes,
and Ratzinger believes that as Pope, his eyes are the same as the eyes of
God. Posted 4/22/2005 8:26 AM - email it
Although he tried to remain loyal to the
Catholic Church, Galileo's adherence
to experimental results, and their most
honest
interpretation,
clearly
contributed to the rejection of blind
allegiance
to
authority,
both
philosophical and religious, in matters
of science.
Psalms
93:1;
96:10;
104:5,
1Chronicles 16:30 and Ecclesiastes
1:4,5 speak of the (in some sense)
"firm" and "established" position of the
earth. Galileo defended heliocentrism,
and claimed it was not contrary to
those Scripture passages.
The writers of the Scripture wrote
from the perspective of the
terrestrial world, and from that
vantage point the sun does rise
and set. In fact, it is the earth's
rotation
which
gives
the
impression of the sun in motion
across the sky.
The decree did not prevent Galileo
from
discussing
heliocentrism
hypothetically. For the next several
years Galileo stayed well away from
the controversy.
