To be more clear pertaining to my situation, I have been attending the SSPX for around two years as this point. Before then, I attended the new mass. I have been to the Novus Ordo for confession many times, yet I am now scrupulous that those confessions may have been invalid.
Now this isn’t for any particular reason, as in, I believe the correct form, matter, and words were present during the sacrament, but that I am scrupulous based on the sole fact that my absolution came from a Priest within the Novus Ordo.
Fr. McFarland of the SSPX does ease my conscious on this topic, after ensuring that the ordinations in the New Rite ARE indeed valid according to him in a video (Crisis Series #39) put up by the SSPX YouTube channel. Though I trust Fr. McFarland's opinion on the subject (in reference to the validity of their ordinations), the worry is still there.
The sins I've confessed are many, and frankly extremely embarrassing, and the thought of having to confess them again makes me sick. I feel like it'd be similar to another first confession for me.
If I’m worried, should I just re-confess my sins anyways?
Should I stop being so scrupulous and put my faith in God?
Should I not focus on it so much because, regardless of if those confessions were invalid (which I have no idea about) all of my sins have been forgiven at my last confession with a Traditional Priest anyways?
If I believe my absolutions were valid, yet it turns out they weren't, does any fault really fall on me?
Any answers would be great.
