I am not familiar with the “PCE” (which I am guessing means Presbyterian Church of England, but that may not be correct),
		
		
	 
PCE in all my writings stands for
 Pre-
Conception 
Existence theology and nothing else. We have gone over all this before...
	
		
	
	
		
		
			The idea that “ a holy GOD going against HIMself by creating sinners by means of HIS boy Adam according to HIS will” is perfectly consistent with the meticulous predetermination of Calvinism!
		
		
	 
And after I so strongly repudiate this theology of complete predeterminism of everything you still want to label me Calvinist?  Why waste your time? Why the inflexibility? 
	
		
	
	
		
		
			How does one make a decision before they exist, much less “before the creation of the physical universe…”?
		
		
	 
No one exists before they exist nor can do anything before they exist. This is why I do not use the misnomer of "pre-existence" to refer to our existence as spirits in the spirit realms before the creation of the physical realm.
Another way to think of pce theology is to refer to this time as our 
pre-earth existence....the time of election, reprobation and our pre-sinful free will sometimes referred to as
 before the foundation of the world. It is not existence before we existed...
Now before you get too all het up, The bible tells us that at the sight of the creation of the physical universe
 Job 38:7 [that]
...the morning stars sang together and all the sons of God shouted for joy? Berean Standard Bible  
IF you keep insisting that the only creation was the physical creation then you are obviously irrationally contending that some people sang HIS praises before their creation against all logic!
I am contending that 
all the sons of GOD refers in fact to 
ALL the sons of GOD, all the people HE ever created.  That means that if you are a created son of GOD then you were there singing your heart out for HIS glory!!! It also means I have stronger support in the bible for our pre-conception existence than you do for being created by your conception in the womb.
	
		
	
	
		
		
			Infants are sinful in nature , but are not culpable for their condition until they knowingly and willingly sin.
		
		
	 
IF infants are sinful by their created nature as humans as you say then the holy GOD does create evil people, and you are the Calvinist!   
And, if they are not culpable for their condition, then why are the consequences of being culpable for that condition visited upon them, that is, death and suffering???  
Proverbs 17:15 Acquitting the guilty and condemning the innocent, the Lord detests them both. 
And IF...
Romans 5:10  For if, when we were God's enemies, we were reconciled to him through the death of his Son, how much more, having been reconciled, shall we be saved through his life!  To highlight: if we were enemies at His death then this implies that
 our enmity with HIM was before our supposed creation so either HE created us as evil by HIS eternal plan as the Calvinists contend 
OR 
we were created as innocents pre-earth and in sheol we made our true free will decisions to reject all or part of HIS purpose for us and self created ourselves as HIS enemies BEFORE our sinful life on earth needing reconciliation by the death of HIS Son.
I notice you do not try to eisegete 
Matt 13:36 Then He left the crowds and went into the house. And His disciples came to Him and said, “EXPLAIN to us the parable of the tares of the field.” 
An explanation of a metaphor that is itself a metaphor only extends the metaphor, it does not explain it or reveal its hidden meaning.  Therefore such an explanation must not have any literary device in it, no hyperbole nor metaphor in it at all.
 It would have to be able to be taken at plain face value.
 37 And He said, “The one who sows the good seed is the Son of Man, 38 and the field is the world; and as for the good seed, these are the sons of the kingdom; and the tares are the sons of the evil one; 39 and the enemy who sowed them is the devil,     
in which Christ clearly says people are SOWN, not created, into mankind and are already sinners when this happens, both the sinful people of the kingdom who are never under condemnation and the demonic reprobate who are condemned already as per 
Jn 3:18...
The Son of Man sows the people of the kingdom into the world. The devils sows the people of the evil one into the world. That means they are separated into these groups 
before they get sown / born into this world...and for those who need the reminder, to sow does not mean to create but to move from a storage bin to a field for growing.
