Mea Culpa

What're you saying? He said ";I'm sorry, I committed a sin, I made a mistake. I asked (?????) to forgive me... please forgive me."; He said ";Mea Culpa,"; can you put it better? ";I'm saying I'm sorry, I made a mistake, I made... I committed a sin, I made a mistake. And I'm never gonna do it again, I never did it before and I'm never gonna do it again.";
