If it's true that I do not really know what my past has been, because all I have is a collection of memories, none of which I can verify for sure . . .
If I do not know the significance of what I did in the past, nor have any way of telling whether I could have done otherwise . . .
If moreover in making a judgement about what I have done I do not know how many relevant factors there may be which I did not know, and still do not know, and may never know . . .
How on earth - or later in heaven - can I be held accountable for my life and what I have made of it? And why does the Church in its liturgy invite me on every possible occasion to own and confess and repent my individual wrongdoing?
Individual responsibility may be no more than a necessary fiction. But if so what kind of necessity is this?
