***We say, pronounce, sentence, and declare that you, the said Galileo, by reason of the matters adduced in trial, and by you confessed as above, have rendered yourself in the judgment of this Holy Office vehemently suspected of heresy, namely, of having believed and held the doctrine—which is false and contrary to the sacred and divine Scriptures—that the Sun is the center of the world and does not move from east to west and that the Earth moves and is not the center of the world; and that an opinion may be held and defended as probably after it has been declared and defined to be contrary to the Holy Scripture; and that consequently you have incurred all the censures and penalties imposed and promulgated in the sacred canons and other constitutions, general and particular, against such delinquents. From which we are content that you be absolved, provided that, first, with a sincere heart and unfeigned faith, you abjure, curse, and detest before use the aforesaid errors and heresies and every other error and heresy contrary to the Catholic and Apostolic Roman Church in the form to be prescribed by us for you.
And in order that this your grave and pernicious error and transgression may not remain altogether unpunished and that you may be more cautious in the future and an example to others that they may abstain from similar delinquencies, we ordain that the book of the “Dialogues of Galileo Galilei” be prohibited by public edict.
We condemn you to the formal prison of this Holy office during our pleasure, and by way of salutary penance we enjoin that for three years to come you repeat once a week at the seven penitential Psalms. Reserving to ourselves liberty to moderate, commute or take off, in whole or in part, the aforesaid penalties and penance.
And so we say, pronounce, sentence, declare, ordain, and reserve in this and in any other better way and form which we can and may rightfully employ.

Was this ruling an error of faith or simply a difference of opinion or an example of fallibility that was dealt with embarrassingly harsh)?
Does that mean that matters of abortion, same sex marriage, birth control,etc are also, simply differences of opinion that can be dealt with as any organization is entitled, as it sees fit at the time but so long as you remain a Catholic, and your conscience is properly clear, means nothing to our Father in Heaven?
Please note I am asking questions.

Scott Hahn called it “the original passing of the buck” 
I think the Ecumenical Councils guided by the Holy Spirit got it right by condemning both Pope Honorius & Patriarch Sergios as heretics as both taught/wrote that Jesus had one Will and anathemas placed against both of them.
