What religious order was Galileo arguing with?

Answer 1

Galileo had a quarrelsome nature and said he was celeverer than all the cardinals. So his disagreement was with the whole Catholic Church.

He promoted Copernicus's theory, which the church authorities said was OK as a theory, but he was told not to say it was the absolute truth, because that contradicted the scriptures as they stood then.

But later he published a book supporting the heliocentric idea, in which the Pope was portrayed as a simpleton. He was asked for proof of the theory, but could not produce one in court and recanted his views.

But many years later Kepler's theory of the planets' orbits was backed up by Newton's theoretical discoveries. The new theory, which is still in use today, retained Copernicus's idea of having the Sun at the centre, so the heliocentric idea promoted by Copernicus and Galileo was eventually demonstrated to be correct, many years after their lifetimes.

Answer 2

Galileo was a Christian he was baptized into the Catholic Church.

Answer 3

he had no religion cause he was against the church, infact he proved theroies which speak against the church. Like the helicentric theory. According to my Asain friends.
