I think the question is what is meant by 'worship'. All sacrifices were replaced by Jesus who sacrificed Himself. But the followers of Jesus are expected to "sacrifice praise" to God. Worshipping means acknowledging God and praising (or thanking) Him for everything. The first sacrifice in the Bible was brought by Noah as thanks, after he was saved from the flood.
The next instance of sacrifice in the Bible was where God asked Abraham to sacrifice his son ("Take your son, your only son, Isaac, whom you love"), and then replaced that sacrifice with a ram ("He went over and took the ram and sacrificed it as a burnt offering instead of his son.") These were the precedents of the ritual of sacrifice, and which were fulfilled (given meaning) by the sacrifice of Jesus.
Exodus 23:25
Worship the LORD your God, and his blessing will be on your food and water. I will take away sickness from among you,
Romans 3:25
God presented him as a sacrifice of atonement,[Or as the one who would turn aside his wrath, taking away sin] through faith in his blood. He did this to demonstrate his justice, because in his forbearance he had left the sins committed beforehand unpunished–
Matthew 9:13
But go and learn what this means: 'I desire mercy, not sacrifice.'[Hosea 6:6] For I have not come to call the righteous, but sinners."
Mark 12:33
To love him with all your heart, with all your understanding and with all your strength, and to love your neighbor as yourself is more important than all burnt offerings and sacrifices."
Romans 12:1
Therefore, I urge you, brothers, in view of God's mercy, to offer your bodies as living sacrifices, holy and pleasing to God–this is your spiritual[Or reasonable] act of worship.
You see the meaning becoming clear? God's law and orders had to be there for the mercy to have meaning. It is still that way.
The church is only a lie if they do not act as a church outside the building they use for worship; it means they don't know what they are doing. One part of finding the truth is exposing the lies. Such as killing people in the name of God.
Does that answer your question ndrs?
