Then your idea of God is that he’s imperfect, because he needs
something God doesn’t need us. He wants us to a) act out of filial respect for Him, not out of fear or obligation. He respects the free will He gave us. b) cooperate in His plan for salvation for our lives, for our salvation is ongoing. (1 Cor 1:18, 2Cor 2:15, Phil. 2:12, 1 Pet 1:9)
Penance, atonement, and mortification for our sins is necessary because:
- Although our Original Sin was washed away in Baptism, we still have concupiscence. We have to make up for the mortal sins we choose to commit.
- It can also mean mortification or other penances to increase humility, express contrition, and build up the Body of Christ. (This goes further into redemptive suffering for the whole body of Christ. More here, from which this point was taken.) So, our sin affects the body of Christ as much as our redemptive suffering, and collectively our actions reflect the state of His church.
Love thy neighbor, keep the sabbath holy, Love your God, No need to apply.
Perhaps in recounting specific commandments we are looking to adhere to the letter of the law, not its spirit. The Golden Rules trump every commandment: “Love your neighbor as you love yourself” and “Do unto others as you would have them do unto you” are umbrella commandments that contain all others.
What makes God sad? Whatever God allows to make Him sad. What makes God angry? Idolatry. We don’t make God feel anything, though parts of the nature of God is revealed in Scripture: Ps 103:8: mercy, graciousness, patience; Ps 86:15: compassion; Deut 6:15: jealousy. God’s nature is a paradox, defined by what we attribute to Him.
But if we haven’t injured God then we don’t need to pay any sort of satisfaction to him - we don’t need to apologise to Him…[or] offer a sin sacrifice…Yet He clearly required and requires all of those things of us when we sin!
We hurt
ourselves, not God, and we still need to say, “My bad!” because in sin, a person has put a barrier between himself and His grace. A person can separate himself and obstruct the grace that can work in our lives and refine us for the next life. This doesn’t hurt God, but it blocks His will for us, and that’s why we have to atone. When we sin, we are consciously falling short of his standards of behavior towards Him and others. We need to open that channel of grace between Him and us. It may or may not
hurt God, though it impedes His work.
How does saying an act of Contrition to God heal the inury to myself?
We say we’re sorry for our choices to separate ourselves from Him and His free grace. Making amends and apologizing is accepting the consequences of our actions and repairs the conditions of our immortal souls. It puts us back in the position to cooperate in God’s plan of salvation and purification so we may come before Him. Sin does not injure God. It injures our relationship with Him. It damages our chances of the beatific vision, for nothing unclean can enter Heaven.
So you’re saying I need to apologise to my father and require his forgiveness for hurting my sister? No sir - I apologise to my sister alone and require my sister’s forgiveness alone. My father doesn’t enter into it.
Sin not only affects God, but affects the whole body of Christ. First, we are the emissaries of His church, and our behavior must reflect that. Second, regarding your hypothetical situation, Christ said that, “Inasmuch as ye have done it unto one of the least of these My brethren, ye have done it unto Me.” That goes for corporal and spiritual works of mercy as much as a snide remark or a knuckle sammitch. Third, in the weekly Confiteor at Mass, we “confess…to you my brothers and sisters…” You are apologizing to the Church, the Bride of Christ, for hurting another member of the body. Sin affects everyone, for as you are cut off from God’s grace by it, you are also separated from the communion with His church.
