If what you are claiming is, in fact, true, then we should be able to see the angular size of the Sun change twice a day as opposed to twice a year.
Please Jehanne, calm down and stop trying to undermine the geocentric order of the universe by challenging everything a biblical geocentrist has to say. Instead try to understand the physics of it.
The two motions of the sun, daily and annually have different causes. In the G order the universe turns around the earth every day bringing day and night as Genesis says. It is this spin that shows us the sun where it is in the universe every day.
Then there is another movement of the sun WITHIN the universe, its annual journey from tropic to tropic over the equator once a year - to bring the SEASONS on earth as Genesis says.
Thus the sun is on an ongoing angular movement every day. Aphelion and perihelion happens only once a year.
Now if there were instruments accurate enough they would find the size of the sun on its annual journey changes even during one day.
There is no magic or tricks in measuring the changing size of the sun relative to the earth every day every year. If the size changes in 365 days then 1/350th of this change will happen in one day. Both Gs and Hs will see the very same thing.
Note I refer to myself as a biblical geocentrist. I realise that science, physics, the empirical method of man is NOT able to say with certainty what this order is. Thus knowing by REASON is not possible.
But there is a second route to knowing the order of the universe, REVELATION. The Bible reveals a geocentric order as illustrated by all the Fathers, a papal decree and its confirmation by other popes.
That is good enough for me. 'I am the truth' says Jesus, so I will go along with him and KNOW no heliocentrist will prove Him wrong, no matter how hard they try, including yourself Jehanne. Why not think about it and stop fighting the faith of all the Fathers and the whole Church until Galileo's attack on this revelation. Show a little extra faith, join St Robert Bellarmine as a biblical geocentrist and enjoy the omnipotence of God as Creator of such a visible cosmos. See the heliocentric heresy as an attack on His omnipotence, one of the most successful lies even
fooling even the elect.
The truth will set you free from the prison of modern 'science.'
