Romans 3:23
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.
