Whenever I do my first communion I am going to make up random things during it. I'll leave out some things that I don't feel comfortable sharing, and replace them with equally severe if not more severe confessions.
How are you going to explain your made up confessions?
I'll lie and say it's because the priest at my church told me to.
Blaming the priest for your lies doesn't change the fact that you lied in confession and broke your faith. Be honest and take the forgiveness that comes with it.
I'm not going to repent, I'm just going to say I'm sorry so that the priests won't suspect I'm lying.
Why even go to communion if you're just going to lie and add even more sins on to the list? It makes no sense to lie to your faith, because the whole point is to wash away your sins-- why create new ones while doing that? It would be like taking a bath in mud.
