By church, do you mean the Roman Catholic church? The same church which was in the habit of burning at the stake anyone who dared disagree with them?
The relationship between the church (Roman and Protestant alike) and heliocentrism is a long one, and full of complexity.
Here's a very thorough treatment of the subject you may find useful.
The involvement of the Roman Catholic Church in the development of heliocentrism.

The theory that all matter in the universe emanated from a single source, or "the hypothesis of the primeval atom" was put forth by the Jesuit astronomer
Monsignor Georges Henri Joseph Édouard Lemaître.
This theory of course, is a complete contradiction to the Genesis account of Gods creation. Many argue that when God said "let there be light", this was the beginning of the universe, and site the "Big Bang" as merely our scientific understanding of the event in question.
Side note; the word "universe" cannot be found in the original manuscripts of either the Hebrew or Greek scriptures. Many modern translations render "cosmos" as universe, a subtle but noteworthy insertion of modern cosmological theories into the text.
But I digress.
However, when one views the text we clearly see the Spirit of God hovering upon the face of the waters "before" light had been created.
Genesis 1:1-3 (KJV)
"In the beginning God created the heaven and the earth.
And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
And God said, Let there be light: and there was light."
In fact, we have earth and water already mentioned before the six days of creation began, prior to Gods creation of light, the division of light from darkness, or the division of the waters causing dry land to appear.
None of this either confirms or denies the shape of the earth. But it does draw into question the idea of the Big Bang, which is clearly the source of all modern heliocentric cosmological models.
Could it be that evolutionary cosmology is just as questionable as evolutionary biology? And why would anyone who doubts the veracity of the claims of evolutionary biology, be more inclined to agree with the claims of evolutionary cosmology? Its an inconsistency of argument which has always left me scratching my head.
But of course, everyone is free to draw their own conclusions.
