The context is what it appears to be, and what it has always meant in Christianity.
So then "hate your mother and father" in Matt 10 should be isolated from all other Bible texts about loving our neighbor as ourselves as in Matt 22?? in your POV?
The apostles were given the authority to forgive sins just like it says.
No text says 'The apostles' rather it is always "you" and it is in fact "each one of you" in Matt 18 just as in Matt 6 "forgive us our debts as we forgive our debtors". There is never a "just the Apostles" qualifier
That's the reason for Paul's "double forgiveness" of the Corinthian:
2Co 2:10 To whom ye forgive any thing, I forgive also: for if I forgave any thing, to whom I forgave it, for your sakes forgave I it in the person of Christ;
That is a reference to the church discipline he called the church to exercise in 1 Cor 5 -- disfellowshiping someone who was in open sin - to try and convince them to repent and return. It was a corporate action by the entire church to cast that person out.
2 Cor 2:5 But if anyone has caused sorrow, he has caused sorrow not for me, but in some degree—not to say too much—for all of you. 6
Sufficient for such a person is this punishment which was imposed by the majority, 7 so that on the other hand, you should rather
forgive and comfort him, otherwise such a person might be overwhelmed by excessive sorrow. 8 Therefore I urge you to reaffirm
your love for him. 9 For to this end I also wrote, so that I might put you to the test, whether you are obedient in all things. 10 But one whom you forgive anything, I also
forgive; for indeed what I have forgiven, if I have forgiven anything,
I did so for your sakes in the presence of Christ, 11 so that no advantage would be taken of us by Satan, for we are not ignorant of his schemes.
He calls for the entire church to forgive the repentant offender
2 Cor 7:8 For though I caused you sorrow by my letter, I do not regret it; though I did regret it—
for I see that that letter caused you sorrow, though only for a while— 9 I now rejoice, not that you were made sorrowful, but that
you were made sorrowful to the point of repentance; for you were made sorrowful according to the will of God, so that you might not suffer loss in anything through us. 10 For the sorrow that is according to
the will of God produces a repentance without regret,
leading to salvation, but the sorrow of the world produces death. 11 For
behold what earnestness this very thing, this godly sorrow, has produced in you: what vindication of yourselves, what indignation, what fear, what longing, what zeal, what punishment of wrong! In everything you
demonstrated yourselves to be innocent in the matter. 12 So although I wrote to you,
it was not for the sake of the offender nor for the sake of the one offended, but that your earnestness in our behalf might be made known to you in the sight of God. 13 Because of this, we have been comforted.
