Why wasn't the sun-centered model of copernicus immediately adopted after he proposed it?

The sun-centred model of the universe as proposed by Copernicus was not immediately accepted because it challenged the religious dogma that had held sway in the middle ages because this dogma required the earth to be at the center and man the creation of god as a unique event only on the earth so if helio centrism was to take hold it would relegate man and the earth to a lesser important aspect of the universe.
