There's some Scriptural support for John Calvin's position. Here's one I like off the top of my head:
Since we know that God does not consider the Reprobate to be "His Children" but rather "Children of Satan" (John 8:44), for God to claim these murdered infants as HIS Children is supportive of Calvin's belief that God has chosen to monergistically Regenerate and Save, including them amongst His Elect, those whom He has permitted to die in Infancy.
There's no Scriptural support at all for the wicked Arminian/Wesleyan doctrine of Infant Damnation; but then again, there's no Scriptural support for any of the Arminians' teachings. This is just one particularly detestable example of their many execrable blasphemies.
How does anyone know that Infants are among the elect?
He uses " You belong to your father, the devil, and you want to carry out your father's desire" as a rebuke, an insult not a judgement call.The Children of Abraham
31To the Jews who had believed him, Jesus said, "If you hold to my teaching, you are really my disciples. 32Then you will know the truth, and the truth will set you free."33They answered him, "We are Abraham's descendants[b] and have never been slaves of anyone. How can you say that we shall be set free?"
34Jesus replied, "I tell you the truth, everyone who sins is a slave to sin. 35Now a slave has no permanent place in the family, but a son belongs to it forever. 36So if the Son sets you free, you will be free indeed. 37I know you are Abraham's descendants. Yet you are ready to kill me, because you have no room for my word. 38I am telling you what I have seen in the Father's presence, and you do what you have heard from your father.[c]"
39"Abraham is our father," they answered.
"If you were Abraham's children," said Jesus, "then you would[d] do the things Abraham did. 40As it is, you are determined to kill me, a man who has told you the truth that I heard from God. Abraham did not do such things. 41You are doing the things your own father does."
"We are not illegitimate children," they protested. "The only Father we have is God himself."The Children of the Devil
42Jesus said to them, "If God were your Father, you would love me, for I came from God and now am here. I have not come on my own; but he sent me. 43Why is my language not clear to you? Because you are unable to hear what I say. 44You belong to your father, the devil, and you want to carry out your father's desire. He was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies. 45Yet because I tell the truth, you do not believe me! 46Can any of you prove me guilty of sin? If I am telling the truth, why don't you believe me? 47He who belongs to God hears what God says. The reason you do not hear is that you do not belong to God."
20 " 'And you took your sons and daughters whom you bore to me and sacrificed them as food to the idols. Was your prostitution not enough? 21 You slaughtered my children and sacrificed them [e] to the idols. 22 In all your detestable practices and your prostitution you did not remember the days of your youth, when you were naked and bare, kicking about in your blood.--> This is God's response to ISRAEL, treating the nation as a wayward wife. And this states that God considers all of Israel as His children and yet this contradicts your interpretation of John 8:44
