This entire idea is logically self-defeating in itself.
First, it assumes that potentialities can give rise to actualities. As I've read through
the argument, it also assumes that the new birth itself is synergistic. However, Scripture
calls the new birth a new creation.
A. No potentiality can actualize itself. Only actualities can actualize potentialities.
B. Self-causation is impossible, because in order for that to happen a thing would have to
exist and not exist at the same time.
C. Salvation is described as being a "NEW creation."
D. If salvation is synergistic, then you have a potentiality at least assisting in its own
actualization. This is impossible, because it results in an impossible self-caused
being. A potentiality is actualizing itself, thus it is both actual and potential
simultaneously. This is impossible.
E. The only way this can be avoided in this system is for the thing assisting in the new
creation to be bringing forth a different thing other than itself. This is dualism.
Christian soteriology rejects dualism.
F. Corollary: Syngergystic salvation is ultimately heresy, see proof Five.
Second,
A. We have been told that the will is libertine. The state of the will is symmetrical
before and after salvation. It is free to reject the free gift.
B. We have also been told that it is impossible for a person to be committing grevious sin
and be a Christian.
C. We have been told that the sin which causes the person to lose his salvation is
blasphemy against the Holy Spirit.
D. Therefore, if A and B are true, then C. is false, rendering the doctrine false.
a. Blasphemy against the Holy Spirit is a grevious sin.
b. To move from being saved to unsaved involves the committing of this grevious sin.
c. Therefore, Christians must be able to commit at least one grevious sin, namely this
one.
d. Therefore, it can not be that Christians can not be committing grevious sin, or else he could not commit this one.
e. Premise B contradicts Premise A, for if it is impossible for an individual to do B, then the will is not truly libertine, because according to B. the will is
necessarily bound, not libertine, as it legislates against libertine free will by dictating an impossible act.
Third, relative to the first argument:
A. The understanding of the argument is that believing is a state of actuality.
B. The understanding of the argument is not that the state of disbelieving is a poteniality, but it is a corresponding state of actuality.
C. This necessitates that an infinite regress of actualities are giving rise to other actualities. Chains of infinite regress of cause and effect are impossible within the
theistic worldview, as this is an axiom that theism historically rejects.
D. The only way around this is to say that the state of actuality of belief gives rise to
the state of potentiality, unbelief, contradicting the understanding of the state of
unbelief as being a like symmetric actuality.
E. Additionally, if the state of belief is giving rise to a like state of unbelief, at some point it will have to believe and not believe simultaneously. This is impossible because of the first argument against self-causation.
F. The only way around this is to postulate dualism, in which the new actuality negates the other actuality, however, dualism is impossible, because for dualism to be true,
then all of Argument One must also be true, and the argument has been shown to be false, and dualism is rejected.
Fourth, relative to atonement:
A. Jesus is the propitiation for our sins. For the moment, we will say this is an actual
effective propitiation and atonement.
B. Blaspheming against the Holy Spirit is a sin.
C. Blaspheming against the Holy Spirit is a sin that must be paid for, since Jesus paid
for all our sins.
D. Therefore: a. If a person can lose his salvation because of this sin, it is false
that Jesus paid for this sin. This contradicts Scripture. Additionally, it requires
an actual ineffective propitiation and atonement. These notions are oxymorons.
E. If the oxymoron is antinomious, then it still results in double jeopardy for the person
blaspheming the Holy Spirit, because he is persisting in unbelief and unbelief is a
sin, and this sin has been paid for, but it is nevertheless resulting in him having no
atonement for his sins.
Fifth, relative to atonement:
A. Jesus is the propitiation of our sins. We will now assume this is potential atonement.
B. In a potential atonement, all a person's sins are paid for when faith is added to the
atonement and "credited" their account.
C. Thus, it becomes effective.
D. Therefore, if a person quits believing then they have lost the right to take part in
the propitiation.
E. This crediting is something God does not something that man does.
F. We've been told that God has no hand in a person losing his salvation (unless
Tertullian was correct).
G. If God has no hand in this, then D is false, because the person had no hand in the
crediting Himself. God will have to have a hand in this loss of salvation. A person
can not do this in a way that is grounded in himself, because doing so is monergistic.
Monergism is rejected with regards to justification within this soteriological system,
thus it is contradictory to say that security is conditional and mongeristic from the side of the person losing his salvation.
H. If the loss of a person's salvation is grounded in himself, then God is acting in a
contingent manner, if the loss of salvation is syngergistic (or if the initial point
of the sinner's justification was synergystic.
I. All exegesis and all orthodox theology agree: God is pure actuality without any
potentiality whatsoever in His being.
J. If I. is true, then conditional security is false, because, by definition, salvation is
ultimately grounded in something other than God, which contradicts I. If conditional
security is true, then I is false, because God is ultimately acting contingently, and
can not therefore be pure actuality with no potentiality in Him. Thus, if I. is false, this is heresy.
Conditional security is thus self-defeating on multiple levels. It can not be true. If it
is, it is ultimately false.
