I went to confession this morning with the intention of confessing all venial and mortal sins, including those that I had forgotten to confess and were committed in my childhood. As I said my act of contrition, I just remembered one mortal sin that I forgot to confess. I wanted to confess it, but the priest was already saying the formula of absolution and I did not want to interrupt him because it would be inappropriate of me. Although I did not voluntarily withhold the sin, I am unsure whether I am in a state of grace and permitted to receive Holy Communion.
So basically, am I in a state of grace or should I just abstain from Holy Communion?
