Confession Question

[BG45]

I was thinking about the Sacrament of Reconciliation the other day and a thought came to my mind. Would a priest have to refuse someone absolution if they confessed blaspheming the Holy Spirit?

I got into a bit of an internal debate about it, because I could've sworn I read somewhere it was the unforgiveable sin, but wasn't sure.

From the Catechism of the Catholic Church

CCC 1864 "Therefore I tell you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven." There are no limits to the mercy of God, but anyone who deliberately refuses to accept his mercy by repenting, rejects the forgiveness of his sins and the salvation offered by the Holy Spirit. Such hardness of heart can lead to final impenitence and eternal loss.

From the Code of Canon Law

Can. 987 In order that the faithful may receive the saving remedy of the sacrament of penance, they must be so disposed that, repudiating the sins they have committed and having the purpose of amending their lives, they turn back to God.

A priest is bound to forgive all sins, provided a person has true contrition. Can. 980 If the confessor is in no doubt about the penitent's disposition and the penitent asks for absolution, it is not to be denied or delayed.
