Who in turn were controlled by the church. Ur derr derp, or something.
Galileo's fellow astronomers' skepticism wasn't based on the teachings of the church but rather that of Claudius Ptolemaeus (a heathen) who put forth the astrological model of nearby celestial bodies revolving around the earth. That was the accepted science of the day, which the church happened to agree with. It was the apparent absence of the shifting of the stars in relation to movement of the earth (parallax) which was the sticking point for those astronomers, not the church.
