Forgiveness comes in degrees as you have outlined here. I believe that is different than conditional or unconditional forgiveness.
- Degree: She is ignorant of her sin. We need to forgive her unconditionally and teach her that what she did was a sin.
- Degree: She is not ignorant of her sin. We need to forgive her unconditionally and confront her that what she did was a sin.
Jesus is our example. He forgave us. All those people who crucified him were not ignorant of the fact that they murdered an innocent man. They knew he was innocent, yet they killed him anyway. Jesus still forgave them without condition. Matthew 12:32 says whoever speaks against the Son of Man will be forgiven.
The Holy Spirit is the Grace we receive from Him. If “she” is endowed with the grace of God via the Holy Spirit, and commits sin (blasphemes) against the Spirit of God, that would be unforgiveable - conditional unforgiveness - the condition being that sin (blasphemy) was committed against the Holy Spirit.
Regarding those for whom Jesus prayed, I think that He must not have been praying for the ones who knew He was the Son of God and blasphemed the Holy Spirit, because (as you said) those blasphemers remained unforgiven. Consider the context of Jesus’ words:
Jesus said, “Father, forgive them, for they do not know what they are doing.” And they divided up his clothes by casting lots.
(Luke 23:34)
I infer from this that He was praying for the ones who “divided up his clothes by casting lots,” who were the Roman soldiers who executed Him. They did not know what they were doing, because they thought Jesus was a common criminal–not the Son of God. As Saint Paul the Apostle wrote:
None of the rulers of this age understood it, for if they had, they would not have crucified the Lord of glory.
(1 Corinthians 2:8)
Hence, they did not understand what they were doing. But of the Jewish religious leaders who handed Jesus over to the Romans, He says:
Jesus said, “If you were blind, you would not be guilty of sin; but now that you claim you can see, your guilt remains."
(John 9:41)
Unlike the Roman soldiers, they were not blind to their sin, so they remained guilty and unforgiven.
I think it will help to consider what the word conditional means:
con·di·tion·al
[kuhn-dish-uh-nl]
–adjective
- imposing, containing, subject to, or depending on a condition or conditions; not absolute; made or allowed on certain terms: conditional acceptance.
- Grammar . (of a sentence, clause, mood, or word) involving or expressing a condition, as the first clause in the sentence If it rains, he won’t go.
- Logic .
a. (of a proposition) asserting that the existence or occurrence of one thing or event depends on the existence or occurrence of another thing or event; hypothetical.
b. (of a syllogism) containing at least one conditional proposition as a premise.
In our case, we are speaking of definition (1). Now consider the examples:
**(a) Forgiving the servant. ** Forgiving the servant is dependent on, or conditioned on, his conduct. The master’s forgiving the servant is dependent on his willingness to forgive another.
(b) Forgiving Jesus’ persecutors. Forgiving those who persecuted Jesus was dependent on, or conditioned on, their knowledge of their sin. God forgive those who crucified Jesus if they did not know what they were doing, but did not forgive those who persecuted Jesus by way of blaspheming the Holy Spirit, because they did know what they were doing.
In the case of (a) forgiveness depends on, or is conditioned on, the action one takes when given the opportunity to forgive others as God forgave them. Therefore, according to the definition of the word conditional, case (a) is an example of conditional forgiveness.
In the case of (b) forgiveness depends on, or is conditioned on, the awareness, or lack of awareness, of the sin for which she does not repent. If one is aware she sinned, and refuses to repent, she is not forgiven. If one is not aware of the sin, and does not know she needs to repent, she is forgiven. Therefore, according to the definition of the word conditional, case (b) is an example of conditional forgiveness.
In both cases, there are conditions the person meets to be forgiven. See what I mean?
