I honestly don't think sins can't be forgiven

That is a good speculation, however, we still HAVE the Mass and the Sacraments of Confession, Baptism, etc... The Church has had many many bad times and bad Popes and leaders. Yet for OUR sake God keeps the Church alive and the Sacraments valid throughout time and has for over 2000 years. No, what scared me about the 3 1/2 years was last year when the Mass was shut down completely because of Covid nearly all over the world. BUT it came back. As long as the Mass and the Sacraments are available is is not the 3 1/2 years yet. So everyone get to confession! I do have a feeling it won't be long before the Antichrist manifests and shuts down the Holy Church....

 

Confession is not available everywhere, because of COVID, but a 'perfect Act of Contrition' is not as daunting as it sounds. It doesn't require any intense feeling, or that one must somehow be perfect, just a sincere desire to sin no more, with the implicit intention of confessing when the sacrament again becomes available.

For God to decide that, for a given period, sins would not be forgiveable would be to impose a more severe regimen for those unlucky enough to be alive at a certain time. I have never heard of such a thing and the idea doesn't seem to equate even with the limited human conception of justice, never mind that of Justice Himself. I have always thought that those unlucky enough to have a particularly hard time in this world would, if they had a good heart, have it made up to them in the next. However, if God took this view of unforgiveable sin, it would be a hardship which He could, by definition, not make up for. Doesn't seem right and has echoes of Calvinist Predestinationism. Don't feel bad about it; I'm scrupulous myself, even though I can be more objective when it comes to other people, although I realise part of it is an unreasonable wish for certainty on my own behalf, which I don't extend to others.
