If you forgive the sins of ANY, they are forgiven them

[tonychanyt]

Jn 20:

23 If you [D1 disciples] forgive the sins of any, they are forgiven them; if you withhold forgiveness from any, it is withheld.

Strong's Greek: 5100. τὶς (tis) — 526 Occurrences

of any
τινων (tinōn)
Interrogative / Indefinite Pronoun - Genitive Masculine Plural
Strong's 5100: Any one, some one, a certain one or thing. An enclitic indefinite pronoun; some or any person or object.

Does it mean 'if you forgive any person, they are forgiven'?

No, the genitive means 'sins of any'. G5100 modifies 'sins'. The direct object is 'sins' not people.

Do they have to sin against D1 for D1 not to forgive them?

No, G5100 applies to anyone, not necessarily only people who have interacted against D1. It is not limited to sins against the disciples.

I think it is beneficial to hear what Cyril of Alexandria has to say, i would follow his teachings on this passage of scripture.

"Christ, when He gave the Spirit unto them, said: Whosesoever sins ye forgive, they are forgiven; and whosesoever sins ye retain, they are retained; though only the living God is able and powerful to grant unto sinners remission of sins; for whom could it befit to pardon the transgressions that sinners have committed against the Divine Law, save the Lawgiver Himself? You may, if you choose, see the meaning of the saying from the analogy of human affairs. Who has authority to meddle with the decrees of earthly monarchs, and who tries to undo that which has been ordained by the will and judgment of rulers, save only someone who is invested with regal honour and dignity? Therefore, wise was the saying, Insolent is he who saith unto the king, Thou breakest the law. In what way, then, and in what sense did the Saviour invest His disciples with the dignity which befits the Nature of God alone? The Word that is in the Father cannot err; and this He did, and whatsoever He doeth, He doeth well. For He thought it meet that they who have once been endued with the Spirit of Him Who is God and Lord, should have power also to remit or retain the sins of whomsoever they would, the Holy Spirit That dwelt in them remitting or retaining them according to His Will, though the deed were done through human instrumentality.
They who have the Spirit of God remit or retain sins in two ways, as I think. For they invite to Baptism those to whom this sacrament is already due from the purity of their lives, and their tried adherence to the faith; and they hinder and exclude others who are not as yet worthy of the Divine grace. And in another sense, also, they remit and retain sins, by. rebuking erring children of the Church, and granting pardon to those who repent; just as, also, Paul gave up him that had committed fornication at Corinth, for the destruction of the flesh, that the spirit may be saved, and admitted him again into fellowship, that he might not be swallowed up with his overmuch sorrow, as he says in his letter. When, then, the Spirit of Christ dwelling in our hearts doeth things which befit God alone, surely He is the living God, invested with the glorious dignity of the Divine Nature, and having power over sacred laws"
