Galileo supported Copernicus's heliocentric theory
he observed the stars positions moving, and made infrences that lead him to the Heliocentric theory.
Galileo made important discoveries in dynamics but he contributed little to the debate about the geocentric and heliocentric theories. His quarrel with the church caused a polarisation that was seized on by the reformed protestant church which liked to claim that the catholics were opposed to the truth. But the heliocentric theory was not shown to be the right one until about 100 years after Galileo's time.
The phases of Venus are well supported by the heliocentric system, but they are also supported very well by the previous geocentric system. All you need for Venus to have phases is that Venus should pass between Earth and Sun. That happens in both the heliocentric system and the geocentric system.
Galileo's observations with his telescope supported the concept of heliocentricism. He noted that the satellites of Jupiter and Venus, based on their range of phases, did not match geocentricism supported by Ptolemy. He noted that based on these findings, that the Heliocentric theory was correct.
None of it but Galileo's discoveries with the telescope were very important in raising questions about the old Ptolemaic theory, which was geocentric. However Galileo's discovery of Venus's phases was not a proof of the heliocentric principle because Tycho produced a geocentric model that explained Venus's phases.

Isaac Newton supported the heliocentric system as manifested in his derivation of Keplars laws.

geocentric
He supported Heliocentric, which was developed in the 1400's, otherwise, none of his work would make sense.Geocentric was developed in Ancient Greece, thousands of years go.

They opposed it because at that time there was no evidence strong enough to abandon the old geocentric theory. Science did not have the evidence until the later theories of gravity and the laws of motion were discovered, and it was then possible to calculate that the Sun is so much more massive than the rest of the solar system that it must be at the centre. The church leaders knew about the heliocentric theory and asked for the evidence to support it, which was not available at the time, as was proved at Galileo's trial.
he supported the heliocentric theory
Kepler spent his entire adult life trying to figure out what kind of arrangement would be the simplest and most accurate explanation for the motions we actually see in the sky. He tried several of them, and he eventually determined that the best fit was obtained if the planets, including the earth, all moved in elliptical orbits around the sun. That's heliocentric.
