Look, Ihavequestions1, you are missing the point here.
Jesus died for all our sins, but Catholic teaching, as Salibi noted, is that we are also required to TURN from sin, to REPENT from sin.
If you committed ANY sin, you can be forgiven IF you repent.
If you don’t repent of your sins, then the fact that Jesus died for you and for your sins doesn’t magically take away sins of which you have not repented. Otherwise people would say, “I can sin all I want because Jesus died for my sins so they don’t matter.”
When Jesus talks about “the unforgivable sin”, he means a person’s unrepented rejection of God. In other words, you harden your heart to God/ Jesus/ the Holy Spirit and you do not repent of that.
When you act like this then you have also rejected God’s gift of forgiveness and salvation through Jesus’ death on the cross.
As people have said above, if you are worrying that you committed “the unforgivable sin” then you obviously haven’t rejected God/ Jesus/ the Holy Spirit because you are worried that you sinned against them. If you had rejected them, you wouldn’t care. So you haven’t committed “the unforgivable sin”. You can be forgiven if you sincerely repent.
We are Catholics and our faith is based on Scripture AND Sacred Tradition, so we do not base our beliefs solely on flipping open the Bible and finding something in there, although the Bible is a large part of our beliefs.
I hope this makes it more clear for you.
