because they are dumb
The Church ordered Galileo to abandon the Copernican idea because it contradicted the geocentric view that was widely accepted at the time, which placed Earth at the center of the universe. This geocentric model was supported by certain biblical passages, and the Church believed that Galileo's advocacy of heliocentrism could undermine its authority and teachings. Additionally, the scientific evidence Galileo presented was seen as challenging the established worldview, leading to concerns about the potential for social and theological upheaval. Ultimately, the Church sought to maintain its influence and control over cosmological interpretations.
The church - and many people, because of this - at the time firmly believed the Earth was at the centre of the universe. However, if the earth orbits the sun, then obviously the earth isn't at the centre. This makes the church look wrong (not the religion, just the official body, since they were the ones decreeing this) and was thus labelled blasphemy by them. They ordered him to abandon the idea because basically it made them wrong and they didn't like people knowing that.
It happened after Galileo published a book supporting the heliocentric theory that portrayed the Pope as a simpleton. The official view still supported the scriptural teaching that the Earth was at the centre. The church was unwilling to change its ideas until there was good evidence, which science did not have until the 18th century, so Galileo was taken to court, the lack of evidence was exposed and he recanted. The heliocentric theory, with the Sun at the centre, was eventually accepted when the evidence for it was discovered, which happened well after Galileo's lifetime.
Galileo was constrained from teaching his theories as fact as he couldn't prove the facts that he was teaching. On the whole, the Church was very favorable to Galileo, the last Pope who was dealing with him was even a good friend of his. Nevertheless, Galileo kept insisting he was right, even when he could not come forward with any proof, until he angered every Church official he dealt with.

He must abandon the truth and accept less than the fullness of Faith - that is he must abandon the Church that Christ Jesus founded.
In galileo`s time the catholic church was at authority
Galileo raised ecclesiastic hackles because he challenged the church-sanctioned, astronomical doctrine of his day: that the the earth stood at the center of both the solar system and the known universe.
Galileo challenged church teachings by saying that the heliocentric model of the universe was true
NOOOPERDOODLES
Galileo was forced to recant his theories about the Earth's rotation because of the Church. His theories went against the biblical scriptures and therefore he was forced by the Pope and the clergy to retract all his theories from society.
If you are referring to animal sacrifices, the Church has never practiced that.
When Galileo published his ideas challenging the geocentric view of the universe held by the Catholic Church, he faced opposition from church authorities. They viewed his ideas as heretical and contrary to the teachings of the church. Galileo was eventually tried by the Inquisition and forced to recant his views.
