I’m gonna jump in here. I’m not going to expound on what others have said and it’s all really good. What I’d like to do is examine why we humans would rather confess directly to God instead of to a priest. I’ve asked a few people this question and they all seem to boil their answer down to “its none of their business.” I get that. e.
from Genesis 3:
8 Then the man and his wife heard the sound of the LORD God as he was walking in the garden in the cool of the day, and they hid from the LORD God among the trees of the garden. 9 But the LORD God called to the man, “Where are you?”
10 He answered, “I heard you in the garden, and I was afraid because I was naked; so I hid.”
11 And he said, “Who told you that you were naked? Have you eaten from the tree that I commanded you not to eat from?”
12 The man said, “The woman you put here with me—she gave me some fruit from the tree, and I ate it.”
13 Then the LORD God said to the woman, “What is this you have done?”
The woman said, “The serpent deceived me, and I ate.”
From verse 11, God knew Adam had sinned, so here he asks the question and is actually asking Adam to confess what he had done. And verse 12 is Adam’s response…and his response actually makes the sin worse, he blames another, God…and Eve, for him being disobedient. So instead of owning to his sin, or admitting the sin (confessing) which God was looking for, he blames another. So the result is disastrous.
Same with the Eve…when God asks Eve in v13, God knows Eve has sinned, God is asking Eve to own up to her disobedience. And you can see Eve’s response…she blames the serpent. So, another disastrous response.
From the examples cited above, you can see the when you go directly to God, there is a lot of rationalization, of second guessing, whether we sinned or not.
But in the sacrament, there is no such second guessing. It is direct…we convict ourselves…same as what King David does here:
2Sam 12 (please read the whole chapter, will only cite this verse):
13 Then David said to Nathan, “I have sinned against the LORD.”
Nathan replied, “The LORD has taken away your sin. You are not going to die. 14 But because by doing this you have shown utter contempt for[a] the LORD, the son born to you will die.”
