You are apparently refering to his book Dialogo. I will qualify my statement: I didn't mean to imply Galileo never published. What I had in mind were incidences like what happened between him and Johannes Kepler, when Kepler asked Galileo for one of his telescopes, but being an @ss he refused to give Kepler one. Galileo would pull stunts like write his discoveries to Kepler only in anagrams so Kepler couldn't understand them. What I should have said was Galileo very rarely shared his discoveries.
Indeed, it was the publication of that book which triggered the Inquisition's actions against Galileo. The pretext for the proceeding was, in effect, publishing without permission, but the documents to prove that charge have never surfaced.
Pope Urban VIII suspected that the character 'Simplicio' (or Simplicius; I forget which) was a caricature of himself. I believe Urban initiated the trial for personal reasons and that most of the ten Inquisitors couldn't care less.
The actual charges, and the plea that they extracted from Galileo (said to be under threat of torture) was all about his "heresy" in teaching about the solar system: Heresy charges against Galileo and Galileo's confession.
I will concede the point that the "official charges" were of heresy. However, a number of high Church officials and Jesuit astronomers agreed with Galileo, and many had refuted the Ptolemaic system even before Galileo had been born. (Being a Lutheran, I am thoroughly embarassed that Martin Luther called Copernicus a "fool" for supporting a sun-centered system.) So the official charges were not unanimously supported.
Galileo himself was a commited Catholic and saw no disagreement between science and faith. You no doubt have heard of many scientists who held the same view, such as Kepler, Newton, Pasteur, Linnaeus, Faraday, Babbage, Dalton, and many others.
You might read this (as I have done): The Galileo Affair, by Maurice A. Finocchiaro, University of California Press, 1989. It's probably a more scholarly treatment of the subject than an article in a creationist journal.
Unless you have read the Creation T.J., you are hardly in a position to make that assertion. However, I will take my own advice and look up Finochiaro's book.
It's probably true that the Pope felt insulted, and probably for good reason. And as you point out elsewhere, Galileo did have his supporters. Nevertheless, he was forced to confess heresy, his book was banned, and he died under house arrest. Those are the facts. There's not a lot of room to sweep this event under the carpet. It's one of the most momentous episodes in the intellectual history of the West.
