From my recollection, God only breathed twice, once to create mankind and the other time to give the apostles the Spirit needed to forgive sins.
In the old days, the Jews would have to do animal sacrifices to remind themselves of the cost of sin, the animal sacrifice was but a shadow of the true sacrifice (Christ’s death on the cross). Animals cost different monies, a dove would be fairly cheap, lambs and goats would be common, oxen and bulls would be really big and expensive. So, can you imagine, all the Jews showing up for the animal sacrifice, all of them holding pigeons! Pigeons are cheap, plentiful, and a sacrifice of two birds wouldn’t be that bad.
But, imagine, not everyone was holding a pigeon for the sacrifice? How did they determine which animal was qualified for the sacrifice? The Jews had to profess their sins, shouting to all within earshot, their sins, the priest would then assign a severity for the confessed sins and then the sinners would be assigned a dove, lamb, bull or otherwise.
Adam and Eve sinned against God by eating of the tree of knowledge. When God came walking in the garden, what was the first thing Adam and Eve did? They hid, from the shame of the knowledge of what they’ve done. They, as humans, are very much like me as a human, when I’ve done something very wrong against someone, that one person is the very last one that I want to say anything to.
For you, as a Mormon, do not have a chance for Confession as it is a Sacrament. A Sacrament is an outward sign, using materials and form and matter, for an inner disposition of graces of God.
You may ask for forgiveness of sins with repentance in your heart, God will forgive all that ask for it. Though, you will only have your own confidence that your sins are forgiven, as a Catholic, in the sacrament of reconciliation, have moral certainty that the confessed sins are absolutely forgiven, completely.
