It boils down to "your opinion threatens my beliefs, and as a result, my existence." which is why they're often more sensitive about things.

Y3S!

In Riccioli's first of the 2 books (not all) there's information not commonly translated re; the case w Galileo.

:)

they said that the sun at the centre of creation was heresy

Right.

but that is not herliocentrism

I don't think anybody was using the word heliocentrism at the time, but everybody thought that the solar system, whatever its center was, was centrally located within creation. Therefore, in their view, whatever was at the center of the solar system was at the center of creation. And according to the Oxford English Dictionary, any frame of reference in which the sun is centrally located is a heliocentric frame of reference.

I never said that they rejected any scientific fact on the grounds that it was heretical.

But that fact in no way should lessen the shame of the church over this episode in history.

Are you trying to say that the church hasn't suffered enough for the mistake it admits to having made?

Whatever they understood to be heliocentrism was not a scientific fact

Regardless of its factuality, they called it heresy.

Then why do you persist in claiming that the cardinals rejected heliocentrism as heretical

Because I can read what they wrote.

"The proposition that the Sun is the centre of the world and does not move from its place is absurd and false philosophically and formally heretical, because it is expressly contrary to Holy Scripture.
The proposition that the Earth is not the centre of the world and immovable but that it moves, and also with a diurnal motion, is equally absurd and false philosophically and theologically considered at least erroneous in faith."

Look at the above two statements from the 1633 Papal Condemnation:

From a scientific point of view, the cardinals rightly reject the sun as the centre of the universe but wrongly insist the earth to be the centre.

However, from a doctrinal point of view, while they assert belief in the sun as centre of the universe to be heretical, they assert disbelief in the earth as centre of the universe to be merely erroneous.

This is because, contrary to what you claim, the earth as physical centre of the universe has never been Church doctrine, and therefore disbelief in it cannot be heretical.
