The official translation - though I got most of it - which is puzzling as I have only used Latin in my study of Biology, mostly Botany - maybe I have been watching too many episodes of Father Brown. I prefer the translation - with sins of commission and omission - as done by myself - the translation, that is not the sinning.
I confess to almighty God
and to you, my brothers and sisters,
that I have greatly sinned,
in my thoughts and in my words,
in what I have done and in what I have failed to do,
through my fault, through my fault,
through my most grievous fault;
therefore I ask blessed Mary ever-Virgin,
all the Angels and Saints,
and you, my brothers and sisters,
to pray for me to the Lord our God
