I'm with Roscoe on that one.

The last decree concerning the issue, though, roscoe, was in favor of geocentrism. It would not seriously matter to the Holy See now for there to be a decree on the issue again, of course. Both the heliocentric and geocentric (Tycho Brahe) models have everything in the same position, except with slightly different orbits of the Earth and Sun in relation to each other. So the Gregorian calendar could still work with the geocentric model. You could very much use anything else as a reference point like the planet Jupiter placed as the center and do calculations according to it. Again, this is not all de fide definita dogma, but theologically the Earth is the center of the universe at least anyway.

It is not accurate to say that the last decree(1633) was in favor of geocentrism. The fact is that the idea that the Earth revolves around the Sun is used in the calculation of the Gregorian calendar: see L. Pastor v's 19 and 25 online(there are about 20 pages in each vol that are relevant). If the decree of 1633 were in favor of geo-centrism, the Gregorian calendar would have to be given up.

It is probably more accurate to say that the decree of 1633 was not oppossed to helio or geo- centrism. It has to be remembered also that thitherto, no scientific proof that Earth rev around Sun had been discovered.

IMO the 1633 condemnation of Galileo in astronomical terms is only symbolic as Galileo's actual heretical crimes lie in the area of his major occupation in life--physics.

In a geocentric system, a shifting of the angle of the orbit of the sun would account for the course of the year I imagine. So, it could work still with the geocentric system. Geocentrism was still regarded considerably in the early 1600s, roscoe. Heliocentrism was not necessarily accepted by all at that time. Later on though, there came the acentrism of today where the universe has no center, although heliocentrism would be applied by scientists today to the solar system and Earth.
