Not knowing if there are Roman Catholic nuances tied to that statement, on the surface, I agree.

I'm a Catholic, and the nuances are not there, except to the degree that Catholics like myself would tend to put them within a Catholic framework.

A non-Catholic who believes in repentance would have to examine his conscience so that his repentance would be more than just a vague, "I'm a sinner." Certainly at Final Judgment our specific sins will be revealed to all.

For Catholics, even outside of sacramental Confession, it is good to practice an Act of Contrition, which is a way to pray "directly to God" specifically for forgiveness of sins. The first stage of making a good Act of Contrition requires such reflection.

Although an Act of Contrition does not have to be said an exact certain way, it must involve true sorrow for sins committed, and not only because of the threat of Divine punishment, but because they are offensive to the all-good God. Finally, it ought to include a resolution to sin no more, and to avoid the things that lead to sin.

To be sure.

We Reformed folk will say that sin so permeates our existence that we don't even know the depth of it. God id merciful and doesn't expose it to us at once, otherwise we would crumble under the weight of all of out sin. We certainly should examine ourselves, especially before the sacrament of communion

The Act of Contrition prayer:

O MY GOD, I am heartily sorry for having offended Thee, and I detest all my sins because I dread the loss of Heaven and the pains of Hell; but most of all because they offend Thee, my God, Who art all-good and deserving of all my love. I firmly resolve, with the help of Thy grace, to confess my sins, to do penance, and to amend my life.[1] Amen.

[1] “to sin no more, and to avoid the near occasions of sin” — this phrase was in the version I learned as a child.

That's not repentance.

And conviction by the Holy Spirit that leads one to Christ for forgiveness is no light thing.
