During Absolution, I remembered a sin and waited for the priest to finish. I told him I had something else but he just told me not to worry about it
The reason he told you not to worry about it is because he had already absolved you of all your sins, so even if you had another sin to confess – which I do not believe you did in this case – you’d already be covered.
By definition, if you can’t think of something, you cannot tell someone else about it. Luckily, the Lord knows us better than we know ourselves. He knows you are sorry for
all your sins, whether you can bring them to mind right now or not. So He makes absolution work even when we forget to fess up to something.
Not only that, but I’m unsure as to wether the sin I witheld was mortal or not ( I planned on Confessing that I didn’t mention to my younger siblings that not doing a Penance on Fridays might be a sin soon enough-which I’m not even sure if it’s a sin…I feared I might put their souls in some kind of danger or something similar like that

)
I don’t think that was even an itty-bitty-teensy-tiny sin, let alone mortal! Unless you said it in order to make your sibling feel bad, in which case it might rise to the level of a minor sin. Otherwise, assuming that Marty were correct, it would only rise to the level of being mistaken.
As to Marty and his website.
ARRRGGGGHHHH!!!
With “friend’s” like him, the faithful have very little need of the evil one.
First, the bishops “URGE” us to follow certain norms. That’s URGE, not ORDER, or DIRECT. “We think it would be really good for your souls if you were to do the following…”
Second, Vatican II did indeed seek to “give the spirit of penance greater vitality.” But Marty does not seem to have any idea what that means.
VITALITY means “The capacity to live, grow, or develop”
What the Church wants is for us to grow in our love of Jesus Christ and, out of our living, growing, developing
love for Him, to adopt a spirit of penitence.
See the sequence?
FIRST: We are to seek to love Him more,
SECOND: A natural consequence of loving Him more is the DESIRE to do penance for those times when we fail to respond to His love as we should.
Marty, on the other hand, looks to me a bit like a Pharisee.
