Some Christians believe that "It is possible to have free-will and at the same time be incapable of sinning, but it is not possible to be created in that state".
For example, in my recently asked question How do Christians that believe in creatio ex nihilo answer the question of why human beings are not created with a perfect character from the outset?, this answer affirms:
There are things that even an omnipotent God cannot do. For instance, God cannot create a four-sided triangle. If something has four sides, it is by definition not a triangle.
One attribute of perfect character is having free-will and always using it to choose not to sin.
(Sin is defined as breaking God's law, choosing to go against God's will. But since one can't use free-will to go against one's own will, God is by definition incapable of sinning.)
If God created a being that is totally incapable of sinning it would by definition not have free-will (with respect to sin). And without free-will, it would not have perfect character. So God cannot create a being with free-will that is incapable of sinning.
Yet it is possible for a created being to have free-will and at the same time be incapable of sinning (i.e. to have this attribute of perfect character).
Perfect character is something that a created being must develop over time, by learning to choose not to sin. Eventually, choosing not to sin becomes part of one's nature, while choosing to sin becomes impossible.
Christians have free-will, but their purpose in life is to develop perfect characters that always freely choose not to sin. They can develop this God-like character, but by definition no one can be created with it.
That is how I understand free will, the garden, and heaven. At this point, however, you may believe I have misunderstood your question. If you are questioning whether God could have instantaneously created heaven full of people who are both genuinely free and yet entirely sinless, then I will have to answer no, given the nature of libertarian freedom. Only libertarian freedom combined with the accumulation of choices over time is compatible with sinlessness, and such a timeline virtually necessitates some people making choices that are corrupting, not sanctifying.
For people to be both free in an undeveloped libertarian sense (which is essentially capable of choosing good or evil arbitrarily) and for all of them to never sin is not logically possible. More importantly for your question, even if they never sinned, the process of training their free will to the point where they would never sin (not could) had to occur across time.
In other words, the assumption is made that:
- uncreated beings (e.g., God) can have free-will and be incapable of sinning at the same time, but
- created beings (e.g., us) cannot have free-will and be incapable of sinning at the same time when they are created, although they may or may not achieve that state over time.
So it seems that the concept of free will is assumed to have a twofold nature: one for beings that are created and another for beings that are uncreated. The former are thought to be subject to metaphysical limitations that prevent them from possessing perfect characters at the outset. Instead, they can only attain perfection through a process of maturation over time. On the other hand, uncreated beings are assumed to inherently possess perfect characters without the need for any maturation process (if you are uncreated, you get access to an eternal perfect character "for free").
What is the rationale behind this dual perspective on (libertarian) free will, which posits that created beings necessitate maturation over time while uncreated beings do not require any such process? Does it derive from sacred scripture or from deeper philosophical reasoning? Is this view widely held within Christianity? Can we trace its origins back to ancient Christian thinkers? Are there any historical Christian sources that explicitly and unambiguously support this view?
I've heard more than once the claim that a created being with libertarian free will and having perfect character from the outset would create a logical contradiction. I kindly request that answerers that agree with this claim state the logical contradiction explicitly by presenting a formal deductive argument, or anything as close as possible to that. In particular, I would like to see how the contradiction emerges for created beings and how it doesn't for uncreated beings. Please state your premises and deductive steps clearly, explicitly and precisely.
