There are many versions of the Bible. Which one do you quote from, and is not everything that God gives us holy?
The passages in question are found in all the common versions of the Bible. And it is precisely the doctrine of original sin that says children are born not holy but sinful, which contradicts the justice of God.
The Bible exists in many translations and versions. The passages that matter here, such as the words of Jesus (as) that he was sent to the lost sheep of the house of Israel, are found in all the common editions. If a modern version has changed something, that is not the fault of the one who quotes it.
The idea that everything from God is holy is beautiful. But it is church teaching itself that says otherwise. According to the understanding that goes back to John and Paul, every descendant of Adam and Eve is born with an inherited sin. Then a newborn child is not holy but already guilty before it has done anything at all.
This leads to a troubling picture of God. He supposedly could not simply forgive people, because that would have violated His justice. So He sacrificed His own son, to be punished in place of everyone. Our conscience rightly asks: where is the justice when innocent people are born guilty and an innocent man is punished for them? A verdict that casts a stain on the image of God cannot be right.
Nor, according to the Bible, was this sacrifice voluntary. In the night before the crucifixion Jesus (as) prayed long and in tears that God would let this bitter cup pass from him. No one who willingly gives up his life prays like that.
The Holy Qur’an teaches that every child comes into the world with a pure nature and that no one bears the burden of another. In this way God is seen as both just and merciful.
