Here it is…
From the Canons of Dort
ARTICLE 17

Since we are to judge of the will of God from His Word, which testifies that the children of believers are holy, not by nature, but in virtue of the covenant of grace, in which they together with the parents are comprehended, godly parents ought not to doubt the election and salvation of their children whom it pleases God to call out of this life in their infancy (Gen. 17:7; Acts 2:39; 1 Cor. 7:14).

This does say that the children of the elect are elect, that is, the children who die in infancy.  Does any 5 pointer really believe this?  I’m sure they do, but it is simply a theological extrapolation.  Most people who believe infants go to heaven believe so because of an idea of innocence (the child hasn’t sinned).  Of course, if salvation is received through faith, then a child can’t believe.
Frankly, this is simply theological extrapolation.  My wife and I lost our first baby and I can’t honestly say that I KNOW I’ll see him/her in heaven, but I sure hope to.
The greater problem is that it is OBVIOUS that ALL CHILDREN of the elect must also be elect (hence will be saved); otherwise, why the would argument about the death of children make any sense?  If it is only for those who die in infancy, then God has to volitionally protect the non-elect children from death until they are old enough to die in their own unbelief (huh?).
Yet, to create a categorical declaration that all children of the elect are elect shows the problem with obsessive logical systems.  The framers of Dort left the Word of God on this one. Well…they appeal to 1 Cor 7, but that refers to a believer  (elect) and a non-believer (non-elect).  Technically, then, it must mean that if you had one elect parent you are elect too.
Honestly, this is scripturally silly and embarrassing, and for only one reason–they are stating the unknowable.
If you are a 5 Pointer and agree with this, then please help me understand why this is a legitimate point.
In the meantime, this is an example of why I consider myself a moderate Calvinist (if the definition of Calvinism is Dort).  If the definition of Calvinism is something other than Dort, then it goes to my point that there is NO SUCH THING as a 5 Point Calvinist.
Of course, Calvin died 55 years before the  Synod of Dordrecht.
Thanks,
