Wrong. Most of the Greeks accepted a spherical earth by 300 BC, and it quickly spread to Rome and the rest of Europe and the Near-East. By 1000 AD, belief in a sphere Earth was universal among the educated(read: the clergy and the nobility).
If they believed in a flat earth, then explain to me why priests such as Gautier de Metz were never condemned:

Saint Thomas also believed in a spherical earth and assumed the reader did too, remarking on how all the different types of professionals and educated had their own ways of observing the roundness of the earth. In Summa Theologiae he wrote: "The physicist proves the earth to be round by one means, the astronomer by another: for the latter proves this by means of mathematics, e. g. by the shapes of eclipses, or something of the sort; while the former proves it by means of physics, e. g. by the movement of heavy bodies towards the center, and so forth."
Blessed(or St. if you're NO) Hildegaard also believed in a spherical earth, and again did not present it as a novel idea or cutting edge science, but as well-accepted fact:

The ancient Israelites envisaged a universe made up of a
flat disc-shaped earth floating on water,
heaven above,
underworld below.
[6]The
Hebrew Bible depicted a three-part world, with the heavens (
shamayim) above, earth (
eres) in the middle, and the underworld (
sheol) below.
[22] After the 4th century BCE this was gradually replaced by a Greek scientific cosmology of a spherical earth surrounded by multiple concentric heavens.
[6]In the Old Testament the word
shamayim represented both the sky/atmosphere, and the dwelling place of God.
[30] The
raqia or
firmament - the visible sky - was a solid inverted bowl over the earth, coloured blue from the heavenly ocean above it.
[31] Rain, snow, wind and hail were kept in storehouses outside the raqia, which had "windows" to allow them in - the waters for
Noah's flood entered when the "windows of heaven" were opened.

In the
Old Testament period, the earth was most commonly thought of as a flat disc floating on water.
[17] The concept was apparently quite similar to that depicted in a Babylonian world-map from about 600 BCE: a single circular continent bounded by a circular sea,
[50] and beyond the sea a number of equally spaced triangles called
nagu, "distant regions", apparently islands although possibly mountains.
[51]Medieval European
T and O maps such as the
Hereford Mappa Mundi were centred on
Jerusalem with East at the top.
Azimuthal or
Gnomonic map projections are often used in planning air routes due to their ability
to represent great circles as straight lines.Ha ha! One has to wonder about mapping out and planning air routes as straight lines? Certainly not because the earth is a globe.
